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 donot 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 (10-

50 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.

6. Specifications

The unit is designed for operation in cold rooms, incubators (except CO2incubators)

and closed laboratory rooms at ambient temperature from +4°C to +40°C in a non-

condensing atmosphere and maximum relative humidity 80% for temperatures up to 31°C

decreasing linearly to 50% relative humidity at 40°C.

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.

8. Warranty and Claims

8.1. The Manufacturer guarantees the compliance of the unit with the requirements of

Specifications, provided the Customer follows the operation, storage and

transportation instructions.

8.2. The warranted service life of unit from date of delivery to the Customer is 24 months.

Contact your local distributor to check availability of extended warranty.

8.3. Warranty covers only the units transported in the original package.
