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 attention to sections
marked by this symbol.
Caution! Surfaces can become hot during use.
Attention! Magnetism! Effects of a strong magnetic field on the biological systems
have to be taken in to account. Magnetic fields can affect heart
pacemaker, data carriers, etc.
GENERAL SAFETY
Use only as specified in the Operating Manual provided.
Save the unit from shocks or falling.
After transportation or storage, keep the unit under room temperature for 2-3 hrs
before connecting it to the electric circuit.
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 to the design of the unit.
ELECTRICAL SAFETY
Connect only to the mains with voltage corresponding to the serial number label.
Do not plug the unit into an ungrounded power socket, and do not use an ungrounded
extension lead.
Ensure that power switch and plug are easily accessible during use.
Disconnect the power cable plug from the power socket before moving.
If liquid penetrates into the unit, disconnect it from the electric circuit 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 chemical
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.
Do not leave the operating unit unattended.
Do not use outside laboratory rooms.
Avoid spilling alkaline solutions on an aluminium surface. Alkali can damage
aluminium surfaces.
BIOLOGICAL SAFETY
It is the user’s responsibility to carry out appropriate decontamination if hazardous
material is spilt on or penetrates into the equipment.

2. General Information
Intelli-Stirrer MSH-300i magnetic stirrer with hot plate is designed for simultaneous
stirring and heating of different reagents.
The unit is designed for operation with different size magnetic stirring elements (1050 mm long). It provides liquid stirring with the magnetic element rotation speed up to 1250
rpm (max. speed depends on the magnetic element size, stirred volume, viscosity, glassware
shape, etc.).
Application fields:
CHEMISTRY: stirring reaction ingredients during fine organic synthesis, research in
the organic catalysis field, different viscosity chemical reagents
dissolving.
BIOCHEMISTRY: solutions preparation, dialysis, salt and alcohol sedimentation of
macromolecules, gradient forming in the column chromatography,
etc.
SOIL SCIENCE: biological and chemical substances and samples extraction, research
of the soil and ground chemical and bio-chemical compounds.
BIOTECHNOLOGY: using as a minireactor in the micro-organism cells cultivation, culture
medium preparation, titration, etc.
MSH-300 is equipped with an attachable stand SR-1 that allows inserting different
sensors (temperature, pH etc.) inside the liquid.
The unit is equipped with the sample overheat protection, providing an automatic
switch-off of the device when overheating (30°С over the set temperature).

3. Getting started
3.1. 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.
3.2. Complete set. Package contents:
Standard set
- MSH-300 magnetic stirrer with hot plate .......................................................... 1 pce
- Magnetic stirring element* ................................................................................. 1 pce
- SR-1 attachable stand ....................................................................................... 1 pce
- Power cable ...................................................................................................... 1 pce
- Spare fuse (inside fuse holder) ......................................................................... 1 pce
- Operating manual, Certificate .......................................................................... 1 copy
3.3. Setup:
- Place the unit upon even horizontal non-flammable surface at least 30 cm away
from any flammable materials;
- Plug the power cable into the socket on the rear, and position the unit so that the
power switch and the plug are easily accessible.
3.4. SR-1 stand installation
Remove the screw on the fixing socket at the stirrer back (fig.1/1) and retain for future.
Screw 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.

4. Operation
Recommendation during operation
Using the unit for the first time or after storage, set heating temperature to 100°C and
preheat the plate during 30 min, it will help to reduce moisture inside the unit.
4.1. Connect the unit to a properly grounded power socket.
4.2. Place a glass or another chemical vessel with liquid on the working plate and dip
magnetic stirrer element in it.
Note! Vessel must be flat-bottomed and fit tightly to the
working surface of the magnetic stirrer.
4.3. Plate temperature control. Using the Heating knob (fig. 2/2), switch the heating on
and set the required temperature (linearly, in the 30 to 330°C range). Heating
indicator starts flashing (4 times per second) until the unit reaches the set
temperature.
Note! The heating switches off when the plate temperature exceeds the set
temperature for over 30°С.
Caution! Surfaces become hot during operation. Do not touch to avoid burns.
4.4. Using the Mixing knob (fig. 2/1), switch the mixing mode on and set the required
speed.
4.5. After finishing the operation switch off the Mixing and Heating knobs.
4.6. Disconnect the unit from electric circuit.

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