Page 7: Safety Considerations
The vortex should not reach the stirring bar. The stirring bar must rotate in the center of the sample vessel. Watch the rotational behavior of the mixing stick for slow starts CAUTION! The equipment must not be operated in hazardous locations. 50134805_03.2012 Thermo Scientific... - Page 8 CAUTION! Do not use cleaning agents which attack and corrode the stainless steel surface of the magnetic stirrer (5). CAUTION! In case of repair, the equipment must only be opened by an authorised service agent. Thermo Scientific 50134805_03.2012...
- Page 9 INFORMATION Read the instructions carefully before using the magnetic stirrer. No application of the device by an untrained and inexperienced personnel. INFORMATION Use only in the instructions specified accessories, according to the illustrated configuration. 50134805_03.2012 Thermo Scientific...

Page 10: Equipment Description
(5). The magnetic stirrer (5) is cleared for use in safety laboratories and sterile rooms. Stirring vessel (2) and stirring device (1) do not fall within the scope of delivery. Thermo Scientific 50134805_03.2012... -
Page 11: Function
To stop and restart the stirring device (1), the control unit (9) is fitted with a start/stop key (13). The rotation speed is slowly reduced, and then slowly increased again. 50134805_03.2012 Thermo Scientific... -
Page 12: Startup Procedure
The magnetic stirring system must be switched off before connecting or pulling the connector. BIOSYSTEM DIRECT: The rotation speed control button (6) must always be brought to position OFF first. BIOSYSTEM: Switch off control unit (9) using power ON/OFF switch (18). Thermo Scientific 50134805_03.2012... - Page 13 Connect the power cable (8) to the power input (19) on the control unit (9) and into the mains socket. If a germ-free environment is required, accommodate the control unit (9) outside the sterile area. 50134805_03.2012 Thermo Scientific...

Page 14: Stirring Operation
(e.g. by using a spacer under the stirring vessel), the radius of the pendulum motion will be reduced (Figure 5, right). Keep changing the distance between the stirring vessel (2) and the magnetic stirrer (5) until you achieve an optimum pendulum motion. Thermo Scientific 50134805_03.2012... -
Page 15: Magnetic Stirring Bars
(Figure 3). Any risk of demagnetization by external magnetic fields is completely eliminated. All KOMET series stirring bars can be readily recognized by their two conical ends. 50134805_03.2012 Thermo Scientific... - Page 16 (Figure 4). Alternatively, it can be fixed at the bottom of the stirring vessel with the aid of a centering device (centering device not included in scope of delivery). Thermo Scientific 50134805_03.2012...
- Page 17 The latter prevents the magnetic stirring bar from escaping in a sideways direction. When using the stirring disc, take care to note that it will not rotate of its own accord. Affix it to the bottom of the vessel, for example. Figure 5: Stirring disc with screen 50134805_03.2012 Thermo Scientific...

Page 18: Recommended Rotation Speed Ranges
The stirring bar must rotate in the center of the sample vessel. Watch the rotational behavior of the mixing stick for slow starts CAUTION High speed rotations of the stirring bar can cause a warming of the goods. Thermo Scientific 50134805_03.2012... - Page 19 If you want to reverse the direction of rotation, lock the rotation direction key (15) to position STIR. The yellow LED display in the rotation direction key (15) will light up. 50134805_03.2012 Thermo Scientific...
- Page 20 Release the start/stop key (13). The rotation speed will be slowly increased to the preselected rotation speed. If you want to terminate the stirring process: Switch off the control unit (9) using the power ON/OFF switch (18). Thermo Scientific 50134805_03.2012...
