Safety instructions
• Only use the device under an all side-closed exhaust, or a compa rable
protective device.
• Adapt the quantity and the type of distilland to the size of the distilla
-
tion equipment. The cooler must work properly. Monitor the coolant
flow rate at the cooler outlet.
• The glass equipment must always be ventilated when working under
normal pressure (e.g. open outlet at cooler) in order to prevent a pres-
sure build-up.
• Please note that dangerous concentrations of gases, vapours or parti
-
culate matter can escape through the outlet at the cooler. Take appro-
priate action to avoid this risk, for example, downstream cold traps, gas
wash bottles or an effective extraction system.
• Evacuated glass vessels must not be heated on one side; the evapora
-
ting flask must rotate during the heating phase.
• The glassware is designed for operation under a vacuum of up to 1
mbar. The equipment must be evacuated prior to heating (see chap-
ter ”Commissioning”). The equipment must only be aired again after
cooling. When carrying out vacuum distillation, uncondensed vapours
must be condensed out or safely dissipated. If there is a risk that the
distillation residue could disintegrate in the presence of oxygen, only
inert gas must be admitted for stress relief
•
Caution!
Avoid peroxide formation. Organic peroxides can accumula-
te in distillation and exhaust residues and explode while decomposing!
Keep liquids that tend to form organic peroxides away from light, in
particular from UV rays and check them prior to distillation and exhaust
for the presence of peroxides. Any existing peroxides must be elimina-
ted. Many organic compounds are prone to the formation of peroxides
e.g. dekalin, diethyl ether, dioxane, tetrahydrofuran, as well as unsa-
turated hydrocarbons, such as tetralin, diene, cumene and aldehydes,
ketones and solutions of these substances
.
•
Danger of burning!
The heating bath, tempering medium, evapo-
rator piston and glass assembly can become hot during operation and
remain so for a long time afterwards! Let the components cool off
before continuing work with the device.
•
ATTENTION!
Avoid delayed boiling! Never heat the evaporating flask
in the heating bath without switching on the rotary drive!Sudden fo-
aming or exhaust gases indicate that flask content is beginning to de-
compose. Switch off heating immediately. Use the lifting mechanism to
lift the evaporator piston out of the heating bath. Evacuate the danger
zone and warn those in the surrounding area!
•
Caution!
Never operate the device when the evaporator piston is rota-
ting and the lift is raised.
Start at low speed and lower the evaporating
flask into the heating bath, increase to desired speed. Otherwise hot
tempering medium may be sprayed out!
• Set the speed of the drive so no tempering medium is sprayed out as a
result of the evaporator piston rotating in the heating bath. If necessary
reduce the speed.
• Do not touch rotating parts during operation.
•
Imbalance may result in uncontrolled resonance behaviour of the de-
vice or assembly. Glass apparatus may be damaged or destroyed. In the
event of unbalance or unusual noises, switch off the appliance immedi-
ately or reduce the speed.
• A vacuum may form inside the glassware in case of power outage. The
device will vent automatically when it is switched on again.
• The appliance does not start up again automatically following a cut in
the power supply.
• The device is only disconnected from the power supply network if the
device power switch is off or the plug is pulled out.
• The socket for the mains cord must be easily accessible.

- local temperature peaks.
• Ensure that the stand does not start to move due to vibrations respec
-
tively unbelance.
• Beware of hazards due to:
- flammable materials,
- combustible media with a low boiling temperature.
•
Caution!
Only process and heat up media that has a flash point higher than
the adjusted safe temperature limit of the heating bath that has been set.
The safe temperature limit of the heating bath must always be set to at
least 25 °C lower than the fire point of the media used.

front plate or the main switch on the back right side of the device using
the maximum total weight of 3.1 kg.
The evaporating flask is lifted out of the heating bath.
When using for the first time or after a long period of inactivity, proceed
as follows: use the motor to move the lift several times to the top and
bottom positions by pressing the lift function keys prior to interrupting
the power supply.
Note: Switching off and disconnecting the power supply shows a delay
compared to switching off using the "Power" switch on the front panel.
If the safety lift is not working, please contact the
IKA
®
Service depart-
ment.
For the evaporating equipment (evaporating flask plus contents), the ma-
ximum permissible weight is 3.0 kg! With larger loads there is the risk of
broken glass on the steam pipe!
Ensure that the safety lift has been powered down.
When working with large loads, always use low speeds. Unbalanced
loads can result in a broken steam pipe!
• Removable parts must be refitted to the appliance to prevent the infil
-
tration of foreign objects, liquids etc.
• Protect the appliance and accessories from bumps and impacts.
• Automatic operation: Always check evaporation processes before
starting automatic operation. Automatic operation must not be used
for unfamiliar evaporation processes.
Safety lift
When the device is switched off or the power supply disconnected, the
internal safety lift removes the evaporating flask from the heating bath.
When the safety lift is powered off, it is designed for a maximum total
weight (glassware and solvent) of 3.1 kg.
Sample calculation of total weight with vertical glassware and a 1 litre
flask:
Condenser + receiving flask + evaporating flask + fittings =
1200 g + 400 g + 280 g + 100 g = 1980 g
Maximum solvent load = 3100 g – 1980 g = 1320 g
Due to the design, the safety lift cannot be guaranteed for higher loads!
When using other types of condensers such as dry ice or intensive con-
densers as well as when using return distillation distributors with slip-on
condensers, it may be necessary to reduce the load by the added weight
of the glass apparatus.
Thus, prior to distillation, check whether the lift goes up without power
when laden with the glassware and distillation material.
The safety lift must be checked daily prior to operation. Use the motor
to move the lift to the lowest position and press the "Power" key on the

Useful information
The device is equipped with a piston-operated safety mechanism. The
glass apparatus may contain a vacuum following interruption to the po-
wer supply; vent the system before switching back on. If the power cuts
out, the evaporator piston is automatically lifted out of the heating bath
by an integrated gas spring.
CAUTION!
The safety lift must be checked daily prior to operation. For
more information see the section entitled "Safety Instructions - Safety
Lift"!
In addition to offering a full range of manual and semi-automatic evapo-
ration operating modes, the RV 10 control rotary evaporator can also be
used for fully automatic and quantity-controlled evaporation processes.
Standard fittings for fully-automatic operation include a vacuum cont-
roller, a cooling water differential temperature measurement sensor and
a cooling water flow rate meter. The vacuum can be controlled in both
two-position and speed-controlled pumping operation with the help of
the integrated vacuum controller The device is designed for operation
with a cooling water supply system (e.g. laboratory thermostat), but can
also be run off a water supply line. Please refer to the Technical Data for
information on cooling water pressure, temperature constancy, flow rate
and local regulations.
We recommend using the RV 10.5001 water regulator valve when ope-
rating directly off a water supply line.
This valve allows the cooling water flow rate to be adjusted and automa-
tically cuts off the cooling water supply on completion of the distillation
process.
The RV 10.5002 water filter can be used to prevent particles of dirt pas-
sing from the water supply line into the valve mechanism.
If pressure reduction is required, we recommend fitting the RV 10.5003
pressure regulator valve in the pipe immediately downstream of the pick-
off point.
Automatic volume-dependent distillation:
The apparatus must be
brought up to operating temperature. This is achieved by conducting a
test distillation.
Distillation is a thermal separating process for liquid compounds based
on substance-specific, pressure-dependent boiling points through evapo-
ration and subsequent condensation.
The boiling point temperature decreases with decreasing external pressu-
re which means that work is usually done under reduced pressure. In this
way the heating bath can be maintained at a constant temperature (e.g.
60 °C). Using the vacuum, the boiling point is set with a steam tempe-
rature of approx. 40 °C. The cooling water for the condensation cooler
should not be warmer than 20 °C (60-40-20 rule).
A chemical resistant membrane pump with a vacuum controller should
be used to create the vacuum. The pump is protected from solvent resi-
due by the addition of a Woulff bottle and/or a vacuum separator.
Working with a jet pump to create a vacuum can only be recommended
to a limited extent as the solvents may contaminate the environment
when using these systems.
Speed, temperature, piston size and system pressure all affect the eva-
porator air capacity.
The optimum capacity of the flow-through condenser is approx. 60%.
This corresponds to condensation on approx. 2/3 of the cooling coil.
With larger capacities there is the risk that the uncondensed solvent va-
pour will be extracted.
In order to prevent this, the condenser loading safety monitoring system
can be activated. Before activating the safety monitoring, first carry out
several distillations, noting the value given under menu “Settings”, menu
option “Drive”, item “Maximum heat rejection rate”. Now calculate the
heat rejection rate using the following formula:
Heat rejection rate threshold = maximum heat rejection rate * 1.3
Enter this value under menu “Settings”, menu option “Distillation”, item
“Heat rejection rate threshold”. The device will now stop the measure-
ment and issue an error message if the threshold for the condenser is
exceeded. If the configuration of the condenser equipment or the dis-
tillation process is modified, then it may be necessary to re-evaluate the
maximum condenser loading.
The factory setting for this value is 900 W.

The RV 10 control rotary evaporator allows you to set the desired vacuum using two-position and speed control with the help of the integrated va-
cuum controller and pressure sensor.
Two-position control
A vacuum is made in the glassware with the help of a vacuum pump. The vacuum pump operates at constant speed which generally cannot be ad-
justed. Once the target value setting is reached, the RV 10.4002 vacuum valve interrupts the suction line (included in scope of supply). If additional
switching on and off of the vacuum pump is desired, please use the RV 10.4003 pump control (accessory).
The device will fall slightly short of the target value setting due to the time difference in the millisecond range with the vacuum value, the target value
comparison and the switching of the vacuum valve. Natural leakage from the apparatus now causes another increase in the pressure value of the
system, which in turn is detected by the integrated pressure sensor.
If the target value is exceeded, the vacuum valve is reopened and the vacuum pump in operation lowers the pressure. The pressure curve shown on
the display fluctuates around the set target value.
The pressure difference between activating/deactivating the valve can be set using the vacuum hysteresis value (see Vacuum Settings). The value is set
to 10 mbar as standard.
The quality of the control depends on the suction power of the pump (rotation speed), the tightness of the system and signal delay time of the elec-
tronics used.
Automatic boiling point recognition is not possible when using two-position control.
Schematic view of a two-position vacuum control
Speed-vacuum control
Imprecision of the two-position control is avoided by using the speed-vacuum control.
However a vacuum pump with a controlled speed is needed for speed-vacuum control; the RV10.4002 vacuum valve is not required and must not
be connected!
To do so, connect the vacuum pump (e.g. KNF N920 speed controlled pump) to the port on the rear of the rotary evaporator.
With this kind of control, the speed of the pump, and therefore its suction power, is reduced the closer the measured pressure reaches the target value.
Once the target value is reached, the pump only operates according to the leakage rate.
It is possible to achieve quieter operation and more exact vacuum control.
The speed-vacuum control on the RV 10 is controlled automatically as soon as an appropriate vacuum pump is attached.
Automatic boiling point recognition is possible with this type of control, i.e. the system reaches and keeps the solvent at its boiling point in automatic
mode.
As it is not necessary to know the boiling point of the solvent when in automatic boiling point recognition mode (unlike in the case of volume-depen-
dent distillation), these two operating modes are mutually exclusive.

- The Rotary evaporator sends only at the computer’s request. Even fault
indications cannot be sent spontaneously from the Rotary evaporator to
the computer (automation system).
- Commands are transmitted in capital letters.
- Commands and parameters including successive parameters are separa-
ted by at least one space (Code: hex 0x20).
- Each individual command (incl. parameters and data) and each response
are terminated with Blank CR LF (Code: hex 0x20 hex 0x0d hex 0x20 hex
0x0A) and have a maximum length of 80 characters.
- The decimal separator in a number is a dot (Code: hex 0X20E).
The above details correspond as far as possible to the recommendations
of the NAMUR working party (NAMUR recommendations for the design of
electrical plug connections for analogue and digital signal transmission on
individual items of laboratory control equipment, rev. 1.1).
The NAMUR commands and the additional specific
IKA
®
co mmands serve
only as low level commands for communication between the rotary eva-
porator and the PC. With a suitable terminal or communications program-
me these commands can be transmitted directly to the rotary evaporator.
The
IKA
®
software package, labworldsoft, provides a convenient tool for
controlling rotary evaporator and collecting data under MS Windows, and
includes graphical entry features, for motor speed ramps for example.
The following table summarises the (NAMUR) commands understood by
the
IKA
®
control equipment.
HB 10
Data is exchanged between the heating bath and the drive unit by means
of an infrared link. These are located on the left display side of the hea-
ting bath or on the right side of the drive unit. Do not place any objects
between the two operating units as otherwise the data transfer may be
interrupted (fig. 22)!
RV10 control
The device can be operated in “Remote” mode via an RS 232 or USB
interface using labworldsoft
®
laboratory software.
The RS 232 interface at the back of the device, see fig. 20, is fitted with
a 9-pole SUB-D jack and can be connected to a PC. The pins have serial
signals. The USB interface is located on the left-hand side of the display
on the drive unit and can be connected to a PC using the USB cable
supplied.
Note: Please note the system requirements as well as the operating ins-
tructions and help section included with the software.
USB Interface
The Universal Serial Bus (USB) is a serial bus system used to connect the
RV 10 control with the PC (Fig. 23). Devices that support USB can be con-
nected to each other whilst they are running (hot pluggable) and provide
automatic recognition of the connected devices and their properties.
Use the USB interface in conjunction with labworldsoft
®
for operation in
“Remote” mode to update the solvent library. Navigate to http://www.
ika.net/ika/lws/download/RV10.cfg to update.
Installation
Connect the RV 10 control to the PC using the USB data cable. The RV 10
control will then transmit information to the Windows operating system
to tell it which device drivers are required. Windows will then either:
- Load the driver,
- Install the driver automatically if not already installed,
- Prompt the user to perform a manual installation.

Distillation method
Select between the automatic distillation methods “Volume” and
“100%”. This selection only has an effect during auto-distillation.
Volume
The measured values of the cooling water flow rate and the cooling
water temperature difference form the basis for a heat balance calcu-
lation used to determine the quantity of distillate at every stage of the
distillation. The distillation process is halted when the specified quantity
of distillate has been reached.
100%
The distillation process is stopped when the measured cooling water
temperature difference falls below a threshold value, i.e. as soon as a
solvent has been completely distilled off.
Drying
The cooling water temperature difference is not monitored if this option
is activated, e.g. use in processes for drying powdered media.
Heat rejection rate threshold
A limit value can be set for the heat rejection rate that is appropria-
te for the condenser used; see "useful information" section. The actual
heat rejection rate is calculated during every distillation process. If the
threshold is exceeded, the distillation will be stopped and an error mes-
sage displayed.
Maximum heat rejection rate
The maximum heat rejection rate achieved during the last distillation is
displayed. This value is for information purposes only.
Quantity meas. unit
Select between millilitre and gram as the unit of quantity.
Boiling point recognition
Boiling point recognition can be either activated or deactivated. Boiling
point recognition is only possible in "100%" mode for the distillation
method.
The boiling point recognition function automatically detects the boiling
point of a solvent.

tion remains unaffected.
Switching valves and pump
To check functionality for servicing purposes, use the Service menu to
activate/deactivate directly the valves included in delivery or optional and
the pump, e.g. RV 10.5001.
The RV 10.5001 valve switches the water circuit on and off. This row also
shows the current cooling water flow rate.
Calibrate
The “Calibrate” option is used for calibration of the temperature sensor.
The temperature difference displayed will be calibrated to zero. This ac-
tion cannot be reversed.
The temperature sensor must be calibrated whenever it is replaced or
changed, or if a new temperature sensor is installed.
Please contact the Service department.
The temperature sensor supplied with the system is calibrated ex-works.
Performing calibration
Activate the “Calibrate” menu option by turning the Rotating/ Pressing
knob.
Remove both sensors. To remove a sensor, push back the outer ring to
release the locking device on the push-in connector, while at the same
time pulling the temperature sensor out of the connector, see fig. 26.
To reconnect a temperature sensor, push it into the push-in connector
until the limit stop is reached; an initial resistance will be felt.
Fill water at room ambient temperature into a glass beaker (approx.
500 ml). Fully submerge both sensors into the water, see fig. 27.
Wait until the temperature display in the “Service” menu, menu opti-
on “Calibrate” has stabilised, e.g. 0.2K
Press the Rotating/ Pressing knob.
The temperature difference displayed will be calibrated to zero.
Calibration is only possible within the temperature range +0.5 K to -0.5
K. If the temperature is outside this range, then either a temperature
sensor is faulty or connected incorrectly. Please contact the Service de-
partment.
If the characteristics of the cooling water supply deviate significantly
from the specifications given in the “Technical specifications”, with the
result that the initial conditions for automatic distillation are not achie-
ved, then it may be necessary to recalibrate the temperature sensors.
This may, however, lead to a reduction in the accuracy with which the
distillate quantity is measured in “Auto-distillation” mode.

Efficiency
Balancing requires a precise thermal efficiency to be entered.
The efficiency is dependent on a combination of factors that affect the
distillation process, so it must initially be estimated. The first time a di-
stillation process is carried out should therefore be used for calibration.
Following completion of the distillation process, determine the quantity
of distillate produced and calculate the actual heat rejection rate accor-
ding to the following formula:

Setting the lower end stop
Caution!
Depending on the size of the piston, the setting angle of the
rotation drive and the position of the heating bath and lift, the eva-
porator piston can be in contact with the bottom of the heating bath.
Caution - glass may break!
Limit the lower lift position with the variable end stop.
The lift can be moved to any desired position in manual mode using the
“ ” and “ ” keys. There is no automatic cut-off if a collision occurs.
Press the “ ” key until the lift reaches the desired position.
Note: The evaporator piston should be 2/3 immersed in the heating
bath.
To adjust the stop element (Q), press the centre button (R) on the front
of the lift (Fig. 18).
Move the stop (Q) to the desired position (Fig. 19)
Press the “ ” key until the lift has reached the upper end stop.
Note: The path is limited from 0 – 6 cm.
Check that the limit stop is functioning properly:
Lower the lift by holding down the “ ” key.
The drive stops automatically when the preset desired lower end po-
sition has been reached.
Move the drive back to the upper position.
To activate the safety lift following a long period of inactivity, use the
motor to move the lift to the top or bottom position several times prior
to starting distillation. (See the section entitled Safety Instructions - Sa-
fety Lift)!
Filling the evaporator piston
Prior to filling the evaporator piston, a vacuum controller is used to regu-
late the glass apparatus to the target pressure.
Now fill the evaporator piston using the backfeed line, see fig. 30.
Due to the vacuum present, the solvent is suctioned into the evapo-
rator piston. This enables you to keep solvent loss due to suctioning
to a minimum.
You can also fill the evaporator piston manually prior to creating the
vacuum. The evaporator piston should not be filled more than half its
volume.
Note:
Caution!
The maximum allowed load (evaporator piston and
contents) is 3 kg.
Setting up the heating bath
Refer also to the operating instructions for the heating bath IKA
®
HB 10!
Move the lift to the bottom position and check the position of the
heating bath in relation to the evaporator piston. When using larger
evaporator pistons (2 or 3 litres) or depending on the angle of the
rotation drive, you can move the heating bath 50 mm to the right.
Fill the heating bath with the tempering medium until the evaporator
piston is surrounded by tempering medium to 2/3 of its volume.
Switch on the rotation drive and slowly increase the speed
Note: Avoid creating waves.
Switch on the heating bath using the main on/off switch.
Note: Avoid stress on the glass due to different evaporator piston and
heating bath temperatures when lowering the evaporator piston into
the heating bath!
Note: If non-original accessories are used that are not supplied by
IKA
®
,
then it is possible that the 50 mm travel range provided by the heating
bath will not be sufficient. This applies in particular when using 3 L eva-
porator flasks with foam brake.
Use the
IKA
®
RV 10.3000 mounting plate to extend the heating bath
travel range by 150 mm.
