Safety instructions !

/// Warnings used in this instruction manual

Risk of burning at hot surfaces

�Do not touch hot surfaces without protective gloves�

�Only ﬁll or empty the device when it is cold�

�Let the components cool off before continuing work with the device�

Falling glass vessels

�Check that the glass vessel is securely ﬁxed with the clamp before operating the device�

8

�Before commissioning, read and observe the safety instructions�

�Keep the operating instruction manual accessible for all users�

/// Other risks

Risk of injury from breakage of glass

Incorrect assembly, mechanical inﬂuences from outside or local temperature peaks may produce

critical stress levels in the glass�

�Make sure that the glassware assembly is free of stress�

�Do not subject the device to overpressure during operation�

�The glass equipment must always be ventilated when working under normal pressure (e�g�

open outlet at condenser) in order to prevent a pressure build-up�

�When using oil as the tempering medium, make especially sure that personal protective

equipment is ﬁtted properly�

Risk of injury from breakage of glass with vacuum operation

The glassware is designed to be used at a vacuum to 2 mbar� Failure to observe this may cause

breakage of glass�

�Condense out uncondensed vapours or discharge without risk�

�If there is a risk that the distillation residue will decompose in the presence of oxygen, only

ventilate with inert gases�

Risk of injury through operation with negative pressure

A power failure may produce negative pressure in the glassware and result in injury

following breakage of glass�

�Ventilate glassware manually�

Risk of injury from breakage of glass if weight is exceeded

For the evaporating equipment (evaporating ﬂask plus contents) the maximum permissible

weight is 3�0 kg� Loads exceeding this risk breakage of glass at the steam pipe�

�When working with large loads, always use low speeds� Unbalanced loads can result in

breakage of the steam pipe�

Caution - glass may break

For the evaporating equipment (evaporating ﬂask plus contents) the maximum permissible

weight is 3�0 kg� Loads exceeding this risk breakage of glass at the steam pipe�

�When working with large loads, always use low speeds� Unbalanced loads can result in

breakage of the steam pipe�

Risk of crushing when setting the height

�Check that no objects or devices are located in the area below the hand lever�

9

Risk of injury from breakage of glass with collision

Depending on the size of the ﬂask, the setting angle of the rotation drive and the position of

the heating bath and lift, the evaporator ﬂask may be in contact with the bottom of the heating

bath�

�Set variable end stop to limit the lower lift position�

Risk of injury through toxic / corrosive gases or suspended particles

The open outlet at the cooler may allow gases, vapours or suspended particles to escape in

hazardous concentrations�

�Make sure that any risk is ruled out, e�g� with downstream cold traps, gas wash bottles or an

ecient extraction system�

Risk of burns from glass vessels

The evaporator ﬂask and glassware assembly can become hot during operation and remain so

for a long time�

�Do not touch hot glass vessels without personal protective equipment�

�Allow components to cool off before continuing work with the device�

Risk of burns from splashing with hot tempering media

Do not operate the device when the evaporator ﬂask is rotating and the lift is raised�

�Adjust the speed of the drive to prevent tempering medium being ejected from the heating

bath by the rotating evaporator ﬂask�

Risk of crushing from rotating parts

�Do not reach into rotating parts�

Risk of injury from delay in boiling

Heating the evaporator ﬂask in the heating bath without connecting the rotary drive may delay

boiling�

�Connect rotary drive to avoid delay in boiling�

�Sudden foaming or exhaust gases indicate that ﬂask content is beginning to decompose�

Switch off heating immediately�

�Lift the evaporator ﬂask out of the heating bath using the lifting mechanism and ventilate the

system to normal pressure as appropriate�

�Clear the hazardous area and warn any persons in the vicinity�

Risk of injury caused by electric shock

�Only put together accessories with the power supply cable disconnected�

Risk of injury caused by explosion

�Do not use the device in explosive atmospheres, as it is not EX-protected�

�When using tempering media that could create explosive mixtures, take appropriate safety

measures (e�g� work under an extractor hood)�

Risk of injury through explosive decomposition of peroxides

Organic peroxides can accumulate in distillation and exhaust residues and explode while

decomposing� Numerous organic compounds are liable to form peroxides, e�g� dekalin, diethyl

ether, dioxane, tetrahydrofuran (also unsaturated hydrocarbons such as tetralin, diene, cumene

and aldehydes, ketones and solutions of these substances)�

�Avoid peroxide formation�

�Keep liquids that are liable to form organic peroxides away from light (in particular UV rays)�

�Check liquids for peroxides before distillation and exhaust�

�Eliminate any peroxides present�

10

poisonous liquids, gases, mist, vapours, dusts or biological or microbiological materials)�

�Only work with media for which the energy input during processing is harmless� This also

needs to take into account other sources of energy such as, for example, light irradiation�

parts�

Risk through occurrence of electrostatic discharge

Electrostatic discharge may occur between the medium and drive unit, possibly leading to a risk

from static electricity (e�g� risk of explosion)�

�Rule out any interaction between the medium and drive unit prior to operation�

Risk of damage through imbalance

Imbalance may result in uncontrolled resonance behaviour of the device or assembly� Glass

apparatus may be damaged or destroyed�

�Immediately switch off the device with any imbalance or unaccustomed noise or reduce

speed�

Risk of damage to glass vessels

If the glass vessel is not properly secured, it may fall off�

�Check that the glass vessel is securely ﬁxed before operating the device�

Risk of damage through incorrect use of distillate

�Adapt the quantity and type of the distillation material to the size of the distillation apparatus�

�Check that the cooler is suciently effective.

�Monitor the ﬂow of coolant at the cooler outlet�

Useful information

Distillation is a thermal separating process for liquid compounds based on substance-speciﬁc,

pressure-dependent boiling points through evaporation and subsequent condensation�

The boiling point temperature decreases with decreasing external pressure 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 temperature of approx� 40 °C� The

cooling water for the condensation condenser 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 residue by the addition of a condensate ﬂask 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, ﬂask size and system pressure all affect the evaporator 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 vapor will be extracted�

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, and ﬂow rate�
