2 Safety
2.1 Intended use
The Vacuum Pump V-100 has been designed and built as an item of laboratory
equipment. Its intended use is the evacuation of laboratory apparatus. This is done by
means of a PTFE-membrane pump – with or without regulation by a vacuum con-
troller.
PTFE-membrane pumps are used primarily for the following applications:
Evacuating distillation apparatus, in particular rotary evaporators (Rotavapor®)
Vacuum filtration
Vacuum-drying cabinets
Drying kilns
2.2 Use other than that intended
Use of any kind other than that referred to and any application that does not comply
with the technical specifications constitutes use other than that intended. The opera-
tor alone is liable for any damage brought about by use of the device in a manner
other than that intended.
In particular, the following applications are not permissible:
Use in areas which require explosion-safe apparatus.
Pumping of liquids and solid particles.
Processing samples which could be caused to explode or ignite by impact, friction,
heat or sparks (e.g. explosives).
Use for analysis (e.g. Kjeldahl).
Generation of positive pressure (pressurizing a system).
Operation at ambient temperatures >40 °C.
2.3 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 applica-
ble 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.

8/52 Operation Manual Vacuum Pump V-100
Operator
The operator (generally the laboratory manager) is responsible for the following as-
pects:
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 locally 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]).
BUCHI service technicians
Service technicians authorized by BUCHI have attended special training courses and
are authorized by BÜCHILabortechnikAG to carry out special servicing and repair
measures.
2.4 Residual risks
The device has been developed and manufactured using the latest technological ad-
vances. Nevertheless, risks to persons, property or the environment can arise if the
device is used incorrectly.
Appropriate warnings in this manual serve to alert the user to these residual dangers.
2.4.1 Dangerous vapors
Distillation can produce dangerous vapors that are capable of causing life-threatening
toxic effects.
uDo not inhale any vapors produced during distillation.
uEnsure that vapors are removed immediately by a suitable fume hood.
uOnly use the device in well ventilated areas.
uIf vapors escape from joints or connections, check the seals concerned and re-
place them if necessary.
uDo not distill any unknown fluids.
uObserve the safety data sheets for all fluids used.
2.4.2 Faults during operation
If a device is damaged, sharp edges or exposed electrical wires can cause injuries.
uRegularly check device for visible damage.
uIf faults occur, switch off the device immediately, unplug the power cord and in-
form the operator.
uDo not continue to use devices that are damaged.
2.5 Personal protective equipment
Depending on the application, hazards due to heat and/or corrosive chemicals may
arise.
uAlways wear appropriate personal protective equipment such as safety goggles,
protective clothing and gloves.
uMake sure that the personal protective equipment meets the requirements of the
safety data sheets for all chemicals used.
2.6 Modifications
Unauthorized modifications may impair safety and lead to accidents.

3 Product description
3.1 Description of function
The Vacuum Pump V-100 is intended for evacuating laboratory apparatus to a termi-
nal vacuum of 10mbar (±2mbar).
Once switched on, the V-100 runs in continuous mode unless it is connected to the
Interface I-100 unit. In unregulated continuous mode, the pump runs at a maximum
speed of 1280 rpm and generates a terminal vacuum of 10mbar (±2mbar). The time
required for evacuation depends on the size (volume) of the vessel.
After 1 hour of operation, the V-100 switches automatically to ECO mode. In ECO
mode, the V-100 runs at 70% capacity but still generates the same terminal vacuum
of 10mbar (±2mbar).
The pump can be operated either as a standalone device or combined with optional
accessories (see Chapter3.3 "Specifications supplied", page14).

Evacuation changes the physical and chemical properties of materials. The V-100 is
ideally suited to connection to a Rotavapor R-100 in combination with a Recirculating
Chiller F-1xx. With that combination of apparatus controlled by a controller such as
the Interface I-100, ideal distillation configurations for all commonly used solvents can
be created.

5.1 Important considerations prior to commissioning
WARNING
Risk of irritation of mucous membranes and poisoning from inhalation
of hazardous gases and vapors.
In the process of evacuation it is possible that hazardous substances may be pumped
out at the same time and released into the atmosphere. In addition, it is possible for
such substances to collect as condensation at leaking connections.
uOperate the pump inside a fume hood.
uDirect vapors from the pump outlet into the fume hood.
uIf necessary, wear a face mask and safety goggles.
uIf necessary, only handle pump and accessories with protective gloves.
WARNING
Risk of fire or explosion from flammable solvent vapors.
In the process of evacuation, it is possible for solvent vapors to get into the inside of
the pump and catch fire or explode due to the electric current.
uFollow the guidance notes for the solvents used.
uConnect a Woulff bottle upstream of the pump intake.
uOperate the pump inside a fume hood.
CAUTION
Health risks when handling corrosive substances.
uWhen working with strong acids or caustic solutions, always wear personal protec-
tive equipment (safety goggles, protective clothing, protective gloves).

BÜCHI Labortechnik AG Installation | 5
Operation Manual Vacuum Pump V-100 19/52
5.2 Installation site
uBefore setting up the V-100 and putting it into service, remove the transit fixings
(red) on the rear of the device (see Chapter4.3 "Removing transit fixings",
page17).
IMPORTANT
Risk of property damage from falling equipment (e.g. in an earthquake)
uSecure the Vacuum Pump against falling by means of the lashing eye on the rear
of the device (see Chapter3.2.2 "Rear view", page11).
The installation site must meet the following requirements:
Firm and level surface: at least 200 mm x 300 mm (W x D)
Height: at least 300 mm
Set up inside a fume hood or
feed the pump outlet into the fume hood
Sufficient air supply to the pump cooler
The V-100 is intended for use in laboratory environments (see Chapter3.4.2 "Ambi-
ent conditions", page15).

5 | Installation BÜCHI Labortechnik AG
20/52 Operation Manual Vacuum Pump V-100
The V-100 is connected by a vacuum tubing to the laboratory apparatus to be evacu-
ated. The vacuum tubing leads via a GL14 connection from the pump intake (2) to the
outlet of the laboratory device concerned.
Precondition:
RTransit fixings have been removed (see Chapter4.3 "Removing transit fixings",
page17).
uFit tubing to pump intake (2) using the GL14 cap nut.
If vapors are to be expected during evacuation, we recommend the following:
uConnect a Woulff bottle upstream of the pump intake (see Chapter5.5 "Connect-
ing a Woulff bottle", page23).
uConnect the tubing to the Woulff bottle intake using a GL14 cap nut.
For details of connecting the V-100 to a rotary evaporator (e.g. Rotavapor® R-100)
see the relevant section of the device's operating instructions.
For more information on the use of the V-100, see Chapter3.2.4 "Typical application",
page13.
