2. Safety precautions
Caution! Make sure you have fully read and understood the present Manual
before using the equipment. Please pay special attention 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 pacemakers, data carriers, etc.
GENERAL SAFETY
The protection provided can be ineffective if the operation of the appliance does not
comply with the manufacturer's requirements.
Save the unit from shocks and falling.
Store and transport the unit at ambient temperatures between -20°C and +60°C and
maximum relative humidity of 80%.
After transportation or storage and before connecting it to the electric circuit, keep the
unit under room temperature for 2-3 hrs.
Before using any cleaning or decontamination methods except those recommended
by the manufacturer, check with the manufacturer that the proposed method will not
damage the equipment.
Do not make modifications in design of the unit.
ELECTRICAL SAFETY
Connect only to the mains with voltage corresponding to that on the serial number
label.
Use only the external power supply provided with this product.
Ensure that the power plug is easily accessible during use.
Do not plug the unit into an ungrounded power socket, and do not use an ungrounded
extension lead.
Disconnect the unit from the mains before moving.
If liquid penetrates into the unit, disconnect it from the mains and have it checked by
a repair and maintenance technician.
Do not operate the unit in premises where condensation can form. Operating condi-
tions 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 chemical mix-
tures. 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.
Do not use outside laboratory rooms.
BIOLOGICAL SAFETY
The user is responsible to carry out appropriate decontamination if hazardous mate-
rial spills on or penetrates into the equipment.

3. General information
MS-3000/MMS-3000 magnetic stirrer is designed for effective stirring of different vis-
cosity 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 elements
(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 different sensors (temperature, pH etc.) inside the liquid.
Application fields:
Chemistry
Stirring reaction ingredients during the fine organic synthesis, re-
search in the organic catalysis field, different viscosity chemical rea-
gents.
Biochemistry
Solutions preparation, dialyze, salt and alcohol sedimentation of mac-
romolecules, gradient forming in the column chromatography, 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. Getting started
4.1. Unpacking. Remove packing materials carefully and retain them for future shipment
or storage of the unit. Examine the unit carefully for any damage incurred during
transit. The warranty does not cover in-transit damage. Warranty covers only the units
transported in the original package.
4.2. Complete set. Package contents:

4.3. Setup.
- Place the unit on horizontal even working surface.
- Connect the external power supply unit into the socket at the rear side of the unit
and position the unit for an easy access to the external power supply and the power
switch.
4.4. SR-1 stand installation on MMS-3000. Remove the screw on the fixing socket at the
back of the stirrer (fig. 1/1). Screw in the part of the stand with the counter-nut into
the fixing socket and secure with the counter-nut. Screw in the second part of the
stand into the attached first part.

5. Operation
5.1. Connect the external power supply to the mains.
Note! Vessel must be flat-bottomed and fit tightly to the working surface of
the magnetic stirrer (figure 2).
Figure 2.
5.2. Position the vessel on the center of the platform. Immerse the magnetic stirring ele-
ment.
5.3. Turn the Power switch (fig. 3/1 or 3/3) into the position On.
5.4. Set the required speed using the Speed knob (fig. 3/2 or 3/4). Increase the speed.
Note! A maximum efficient speed is shown in Table 1 for different stirring
element lengths and mixing volumes. Beyond these numbers, mixing
might be unstable.
Note! In the model MMS-3000, if the stirring element loses positioning, the
motor drops the speed, positions the element and slowly picks up the
speed. If mixing is still unstable due to high viscosity or large mixing
volume, consider lowering mixing speed.
5.5. After finishing the operation, decrease the rotation speed to the minimum and turn
the Power switch into position Off.
5.6. Disconnect the external power supply from the mains outlet.
