1. Safety Instructions
The detailed precautions described in the user manual are carefully developed with intent to cover all the
possible risks. Please read carefully before operating this magnetic stirrer:
Warning!
• Read carefully the operating instructions
before use.
• Ensure that only trained staff works with
the instrument.
Protective ground contact!
• Make sure the socket is properly
earthed (with protective ground contact)
before use.
• Never use the stirrer in any way other than the specified in these instructions.
• In case of something abnormal happening during operation, please stop using the equipment
immediately and contact your supplier.
• Effects of the magnetic field must be taken into account (i.e. data storage media, cardiac pacemakers
…). Keep away from high magnetic fields.
• When working, wear the necessary personal protective equipment to avoid the risk of:
- Burns caused by splashing and evaporation of liquids
- Intoxication caused by release of toxic or flammable gases.
• Set up the instrument on a spacious, stable, clean, non-slip, dry and fireproof surface. Do not operate the
instrument in explosive atmospheres, with hazardous substances, or under water.
• Gradually increase the speed, reduce the speed if:
- The stirring bar comes off due to a too high speed
- The instrument is not running smoothly, or the container moves on the base plate
• If the stirring bar contains PTFE, please note:
- Elemental fluorine, trifluoride ion, and alkali metals will corrode PTFE. Halogen hydrocarbons
expand PTFE at room temperature.
- Molten alkali, alkaline earth metals or their solution, as well as elements on second and third
column of the Periodic Table of elements will react with PTFE when temperature reaches 300
~400 ºC
• Process pathogenic materials only in closed vessels.
• The instrument can only be disconnected from the main power supply by pulling out from the mains plug,
not the cable.
• The voltage stated on the label must correspond to the main power supply.
• The instrument may only be opened by experts.
