1. Safety precautions
The following symbols mean:
Caution! Make sure you have fully read and understood the present
Manual before using the equipment. Please pay special at-
tention to sections marked by this symbol.
Attention! Magnetism! Effects of a strong magnetic field on the biological
systems have to be taken in to account. Magnetic fields can
affect heart pace - maker, data carriers, etc.
GENERAL SAFETY
Use only as specified in the Operating Manual provided.
The unit should be saved from shocks or falling.
After transportation or storage keep the unit under room temperature for 2-
3hrs before connecting to electric circuit.
Use only cleaning and decontamination methods recommended by the
manufacturer.
Do not make modifications to the design of the unit.
ELECTRICAL SAFETY
Connect only to the external power supply unit with voltage corresponding to
that on the serial number label.
Use only the external power supply unit provided with this product.
Ensure that the switch and external power supply unit are easily accessible
during use.
Disconnect the external power supply unit from electric circuit before moving
the unit.
If liquid penetrates into the unit, disconnect it from the external power supply
unit and have it checked by a repair and maintenance technician.
Do not operate the unit in premises where condensation can form. Operating
conditions of the unit are defined in the Specifications section.

DURING OPERATION
Do not start operation at maximum speed.
Do not operate the unit in environments with aggressive or explosive chemi-
cal mixtures. Please contact manufacturer for possible operation of the unit
in specific atmospheres.
Do not operate the unit if it is faulty or has been installed incorrectly.

2. General information.
MS-3000/MMS-3000 magnetic stirrer is designed for effective stirring of dif-
ferent viscosity liquids.
MS-3000/MMS-3000 is a compact magnetic stirrer with the stainless steel
working surface. It provides liquid stirring with the magnetic element rotation speed
up to 3000 rpm (max. speed depends on the magnetic element size, stirred volume,
viscosity, glassware shape, etc.).
The unit is designed for operation with different size magnetic stirring ele-
ments (20-50 mm long for MS-3000 and 20-70 mm long for MMS-3000). Other size
magnetic elements may not provide appropriate operation.
MMS-3000 is equipped with an attachable stand that allows inserting differ-
ent sensors (temperature, pH etc.) inside the liquid.
Application fields:
chemistry: stirring reaction ingredients during the fine organic synthesis,
research in the organic catalysis field, different viscosity
chemical reagents dissolving.
biochemistry: solutions preparation, dialyze, salt and alcohol sedimentation
of macromolecules, gradient forming in the column chroma-
tography, etc.
soil science: biological and chemical substances and samples extraction,
research of the soil and ground chemical and biochemical
compounds.
biotechnology: using as a minireactor in the micro-organism cells cultivation,
culture medium preparation, titration, etc.

4. Operation
4.1. Plug the external power supply unit to electric circuit.
4.2. Place a glass or another chemical vessel with liquid with magnetic stirrer bar
in it at the centre of the working plate.
4.3. Turn the Power switch (Fig. 2/1 or 2/3) into the position I(On).
4.4. Set the required speed using the Speed knob (fig. 2/2 or 2/4). Increase the
speed smoothly.
4.5. After finishing the operation decrease the rotation speed to the minimum and
turn the Power switch into position O(Off).
4.6. Unplug the external power supply unit from electric circuit.

6. Maintenance
6.1. If the unit requires maintenance, disconnect the unit from electric circuit and
contact Biosan or your local Biosan representative.
6.2. All maintenance and repair operations must be performed only by qualified
and specially trained personnel.
6.3. Standard ethanol 75% or other cleaning agents recommended for cleaning
of laboratory equipment can be used for cleaning and decontamination of
the unit.
6.4. Improper magnetic stirring elements storage (storing several elements
together, which causes unpredictable magnetic domain disorientation) is one
of the reasons of the magnetic properties deterioration of the element. The
other reason is working at temperatures close to Curie point temperature of
these elements, which is 200°C. Place the element on the unit working sur-
face exactly in the centre and in conformity with the poles and leave for 8-12
hours to have it regained its initial characteristics.
