OPERATING INSTRUCTIONS
Please read through these operating instructions before switching on or attempting to use the equipment. They
describe the use of the VWR Homogeniser S, its installation and maintenance and the appropriate replacement parts
and accessories.
They will help you avoid erroneous use and consequent damage. Although VWR Homogeniser machines are
designed for ease of service, this does not release you from the obligation to inspect your equipment carefully and to
clean it thoroughly.
An important objective of these operating instructions is to fully inform you, the user, about the correct and safe use of
our equipment.
In order to achieve this, it is essential that you should carefully study chapter “Safety” and follow the instructions in this
book.
TARGET AUDIENCE
These operating instructions are intended for all authorised users of our machines/equipment. We distinguish different
user roles, taking account of the different demands placed on the user by the activity to be carried out.
You will find the definitions of user roles with the demands on the user in chapter “Safety”. You can fulfil one or more
of these roles, provided that you meet the corresponding demands.
ORGANISATIONAL MATTERS
If you are unable to find the answer to any question in the operating instructions, please contact the equipment
manufacturer directly.
LOCATION OF THE OPERATING INSTRUCTIONS
The operating instructions can only be of use to you if you always have them to hand. They should, therefore, always
be kept at the place where the equipment is used.

GENERAL SAFETY RULES
Observe the following general safety rules:
•follow these operating instructions,
•in addition, observe the legal obligations and requirements for accident prevention and environmental
protection of the country in which you operate the equipment,
•do not make any modifications to the equipment without the written authorisation of the manufacturer,
•only original replacement parts may be used for repairs,
•before any service work on the equipment, it must be ensured that the electrical supply is switched off,
•after any service, maintenance or repair work has been carried out on the system/equipment, it must be given
a test run by the service technician.

9vwr.com I Instruction manual VWR®Homogeniser S
WARNINGS
Attention
•Ensure that the rated voltage of the equipment matches the supply.
•The equipment may only be opened by VWR authorised service specialists.
•The equipment may not be operated in areas where there is a danger of explosion.
•The VWR Homogeniser S drive may only be operated using the VWR Homogeniser
S power pack.
•The VWR Homogeniser S is not qualified for continuous duty
•VWR Homogeniser dispersion attachments may not be operated dry – the lower
sleeve bearing is cooled and lubricated by the medium being processed. Running dry
will destroy the sleeve bearing.
•Dispersion attachments may only be changed with the power source disconnected.
•Ensure that the venting will never be covered by dust or any other objects. The
efficiency of the motor will decrease.
•Ensure that dispersion attachments are thoroughly cleaned after every use.
•In the event that hazardous chemicals or materials that endanger health can
influence the surroundings or use of the equipment, appropriate countermeasures
must be taken.
•Ensure that before starting up, no foreign objects are in the product.
•When the power supply is connected, never bring hands or tools within the vicinity of
the coupling of the coupled dispersion attachment. Danger of injury by the rotating
shaft and rotor.
•During operation, the coupling bolt may not be actuated; otherwise, the attachment
may fall from the coupling.
•After longer use (15 min) the coupling could get very hot (over 40°C)
•Never turn your VWR Homogeniser S upside down, if a dispersing unit with remains
of fluid is clutched in. The fluid may damage the bearing of the motor.
•In the event of any power cut, the equipment must be switched off; otherwise, it may
start again without proper supervision.
•The stator saw teeth present a danger of injury, as they are very sharp.

10 vwr.com I Instruction manual VWR®Homogeniser S
VWR HOMOGENISER DISPERSING ATTACHMENTS
Dispersing units with diameters of 5, 7, 12 mm are available for the VWR Homogeniser S drive motor.
The quick release coupling makes it very easy to connect the dispersing
unit to the VWR Homogeniser S drive motor.
Simply press the coupling bolt, push the dispersing unit into the coupling
and then release the coupling bolt. The dispersing unit is securely held in
place.
You can check by pulling out or rotating the dispersing unit if it is securely
held in place. If the dispersing unit does not move, it is securely fastened.
If you can pull out or rotate the unit without pressing the coupling bolt,
repeat the above steps until the dispersing unit gets fastened.
Follow the reverse sequence to remove the unit, press the coupling bolt
and pull the dispersing unit out of the coupling.
Attention
•The drive motor must be disconnected from the power supply when removing, exchanging or
connecting a dispersing unit.
•Ensure that the dispersing unit is well fixed in the coupling before activating the drive motor.

INSTALLATION
UNPACKING
Open the dispatch box and check that the contents agree with the delivery note.
Attention
Check all parts for possible transport damage. Inform us immediately of any disagreement or
fault.

13 vwr.com I Instruction manual VWR®Homogeniser S
COMMISSIONING
Connect the drive unit to the electrical supply. Check the supply voltage against the rating plate.
•Immerse the dispersing unit in the product. The optimum depth of immersion of the dispersion unit is about
2/3 of the total depth of product in the container. Never immerse the upper holes of the dispersion attachment.
•Set the desired speed.
Note:
In some cases, it is better to position the dispersion unit off centre in order to obtain more turbulence and better
mixing. This can be achieved by tilting the drive by about 15°.
Attention
•Never allow the VWR Homogeniser dispersion attachment to run without a liquid
phase. Running dry will destroy the sleeve bearing.
•Ensure that the dispersion attachment is thoroughly cleaned after every use.
•Never touch the rotor of a VWR Homogeniser dispersion attachment when rotating.
There is great danger of injury.

14 vwr.com I Instruction manual VWR®Homogeniser S
SERVICE
Your VWR Homogeniser unit is designed for easy service. Nevertheless, it is essential to inspect your equipment
carefully and to clean it thoroughly.
Attention
The equipment must be disconnected from the electrical supply:
•During any work on the equipment, in order to avoid any personal injury or other
damage.
•When changing or removing the dispersion attachment.
DRIVE
Under normal working conditions, the VWR Homogeniser S drive requires no servicing.
Parts such as the motor armature and bearings are subject to natural wear.
We strongly recommend that service work and repairs are carried out only by authorised VWR service
centres or by VWR directly, where original replacement parts are available.
Any unauthorised modification or manipulation of the unit or its equipment leads to immediate annulment of
the guarantee.
HOUSING
The housing is made of styrene butadiene and meets best fire protection requirements. Only suitable cleaners should
be used.

Criteria for changing the bearings:
Basically, it is the operating company that determines when and how often the bearings are to be changed. They
should, however, be changed, at the latest, if:
•the rotor and stator come into contact,
•there is an increase in vibration,
•the rotor projects above the edge of the stator.
