Alexika HB 10: Safety instructions

11

Safety instructions

• Safe operation is only guaranteed with the accessories descri-

bed in the ”Accessories” chapter.

• Use the HB 10.2 cover or the HB 10.1 spray guard.

• Always disconnect the plug before fitting accessories.

• The appliance does not start up again automatically following 

a cut in the power supply.

• The device is only disconnected from the power supply net-

work if the device power switch is off or the plug is pulled out.

• The socket for the mains cord must be easily accessible.

Solvents

Solvents can be hazardous to health. Therefore comply with the 

relevant warnings and refer to the relevant safety data sheet (In-

ternet).

Glassware

The glassware is designed to be used at vacuums down to 1 mbar.

Coated glassware

Coated glass components offer protection against the glass spl-

intering if it breaks under vacuum. Please note that when coated 

glassware is used it is only to the condenser and receiving flask 

to which coating is applied.

For operational reasons, the coating is not applied to the entire 

area of the glass. In particular on the condenser there are areas 

to which no coating is applied, especially at places where joints 

and connections are made.

Evaporating flasks with special heat-resistant coatings are availa-

ble as accessories.

The coating does not offer any protection against damage to the 

glass or breakage of the glass. 

Do not use the glass component if its coating is damaged.  

The use of coated glassware does not release you from the obli-

gation when the device is in use to enclose it on all sides with an 

extractor hood or to employ an appropriate safety device.

Oil-tempered heating bath

If silicone oil is used as a  tempering medium, in the event that 

the evaporating flask fractures there is a risk that on mixing with 

the aqueous solvents (contents of the evaporating flask) the hot 

oil will foam up and spurt out in conjunction with a rapid increa-

se in volume (formation of bubbles by the solvent).

Use the protective device HB10.2.

Locking the steam pipe

Before starting the equipment, always check that the steam pipe 

is correctly locked in place. 

If the lock is not closed the steam pipe together with the at-

tached evaporating flask can fall into the heating bath.

Securing the evaporator flask

Check that the clamp at the connection between the steam pipe 

and evaporating flask is correctly seated.

If the evaporating flask is not secured it can become detached 

during operation and fall into the heating bath.

For protection of the equipment

• The voltage stated on the type plate must correspond to the 

mains voltage.

• Socket must be earthed (protective ground contact).

• Protect the appliance and accessories from bumps and impacts.

• The appliance may only be opened by experts.

For your protection

• 

Read the operating instructions in full be-

  fore starting up and follow the safety in-

   structions.

• Keep the operating instructions in a place where they can be   

accessed by everyone.

• Ensure that only trained staff work with the appliance.

• Follow the safety instructions, guidelines, occupational health   

and safety and accident prevention regulations.

• Wear your personal protective equipment in accordance with 

the hazard category of the medium to be processed. Otherwi-

se there is a risk of splashing liquids.

• When emptying the device use only the recessed handles to 

carry and hold it.

• Set up the device in a spacious area on an even, stable, clean, 

non-slip, dry and fi reproof surface.

• Prior to each use, always check the device and accessories for 

damage. Do not use damaged components.

• 

Caution!

 Only process and heat up media that has a fl ash 

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 fi re point of the media 

used.

• 

Danger of being burnt! 

When in operation the

   upper corner of the bath can heat up to 180 °C.

• Prior to fi lling or emptying the heating bath, the device must 

be switched off and disconnected from the power supply at 

the plug.

• Only fi ll or empty the heating bath when it is cold.

• Empty the heating bath prior to transporting it.

• Never operate the heating bath without tempering medium.

• 

Caution! 

The preferred tempering medium in the heating bath 

is water (up to approx. 80 °C). Low viscosity silicone oils (50 

mPas) with a fl ashpoint > 260 °C are also permitted.

  There is a risk of burning when using tempering media with 

lower fl ashpoints!

•  The  heating  bath  temperature  must  not  be  allowed  to  rise 

to  

a value higher than the boiling point of the sol-

vent at normal pressure, since if the evaporating flask glass 

were to break there would be a hazard due to liquid spray-

ing  out  (for  instance  breakage  of  the  evaporating  flask 

glass during distillation of water using a silicone oil bath).

• When working with the 

IKA

®

 rotary evaporator, be aware of 

a hazard arising from breakage of the evaporating flask glass.

• Be aware of a hazard due to lack of grip on a wet evaporating 

flask, in particular when operating the 

IKA

® 

HB 10 heating 

bath with silicone oil!

• When using as a water bath, the use of demineralised water 

is recommended.

• Always observe the minimum fill level of one litre when using 

oil as the tempering medium.

•  Ensure that the IR interface is not soiled.

• Beware of hazards due to flammable materials.

• Only process media that will not react dangerously to the ex-

tra energy produced through processing. This also applies to 

any extra energy produced in other ways, e.g. through light 

irradiation.

  •  Do 

not

 operate the appliance in explosive atmos-

pheres, with hazardous substances or under water..

• Refer to the operating instructions for the accessories.
