Safety
Proper use
The instrument is designed for steam distillation.
The instrument can be used in laboratories for the following tasks:
Distillation of steam-volatile substances.
Use other than that intended
The use of the instrument other than described in proper use and specified in technical data is use other than that intended.
The operator is responsible for damages or hazards that are caused by use other than that intended.
Specially the following uses are not permitted:

Use of samples, which can explode or inflame (example: explosives, etc.) due to shock, friction, heat or spark formation.
Use of the instrument with other than original BUCHI glassware.
Staff qualification
Unqualified persons are unable to identify risks and are therefore exposed to greater dangers.
The device may only be operated by suitably qualified laboratory staff.
These operating instructions are aimed at the following target groups:
Users
Users are persons that meet the following criteria:
They have been instructed in the use of the device.
They are familiar with the contents of these operating instructions and the applicable safety regulations and apply them.
They are able on the basis of their training or professional experience to assess the risks associated with the use of the device.
Operator
The operator (generally the laboratory manager) is responsible for the following aspects:
The device must be correctly installed, commissioned, operated and serviced.
Only suitably qualified staff may be assigned the task of performing the operations described in these operating instructions.
The staff must comply with the local applicable requirements and regulations for safe and hazard-conscious working practices.
Safety-related incidents that occur while using the device should be reported to the manufacturer ([email protected]).

2.8.1
Hot surfaces
The surfaces of the device can become very hot. If touched they can cause skin burns.
u Do not touch hot surfaces or else wear suitable protective gloves.
2.8.2
Faults during operation
If a device is damaged, sharp edges, moving parts or exposed electrical wires can cause injuries.
u
Regularly check device for visible damage.
u u
If faults occur, switch off the device immediately, unplug the power cord and inform the operator.
Do not continue to use devices that are damaged.
2.8.3
Glass breakage
Broken glass can cause severe cuts.
Minor damage to the ground joints impairs the sealing effect and may therefore diminish suction capacity.
Handle the glass components carefully and do not drop them.
Always place the glassware in a suitable holder when they are not in use.
Always visually inspect glass components for damage every time they are to be used.
Do not continue to use glass components that are damaged.
Always wear protective gloves when disposing of broken glass.
2.8.4
Not suitable titrators
Not suitable titrators can lead to malfunction and wrong results.
u Use recommended titrators only.
2.8.5
Dosing pump defect
A defect dosing pump can spill hazardous liquids on the installation site.
u
Set the On / Off master switch to Off.
u u u
Disconnect the power supply.
Use personal protective equipment to remove the liquid.
Dispose of the remains of the liquid according to the local legal regulations.
2.9
Modifications
Unauthorized modifications can effect safety and lead to accidents.
u u u
Use only genuine BUCHI accessories, spare parts and consumables.
Carry out technical changes only with prior written approval from BUCHI.
Only allow changes to be made by BUCHI service technicians.
BUCHI accepts no liability for damage, faults and malfunctions resulting from unauthorized modifications.

Product description
Description of function
The instrument is suitable for determining steamvolatile substances (e.g. of alcohol, sulfur dioxide, volatile acids) and nitrogen by using Kjeldahl and
Devarda methods (MultiDist).
Steam is introduced into the sample solution to drive out volatile components.
After condensation in condenser the condensate is collected in a receiver solution.
