Safety Regulations

The plug disconnects the instrument. Therefore, place the instrument where it can be quickly disconnected.

Place the power supply in the way to avoid liquid spills directly on it.

The stirred solution may release toxic, dangerous or poisonous gases. Adequate safety measures must be taken, in accordance with the safety regulations in force, including the presence of hood and personal protective equipment (masks, gloves, goggles, etc.).

Position the instrument on a flat surface, with a distance from the wall of 30 cm (at least).

Do not use with explosive and dangerous materials for which the equipment is not designed. The stirrer must not be used in explosive atmospheres, in bain- marie and to stir combustible liquids that have a low combustion temperature. The minimum fire point of flammable solution is 110 °C. Only small amounts (< 50 ml) of flammable liquid can be used with the device.

It is responsibility of the user appropriately decontaminate the instrument in case of dangerous substances fall on or in it. It is also responsibility of the user to use safety substances for cleaning or decontaminating, which do not react with internal parts of the instrument or with the material contained in it. In case of doubts on the compatibility of a cleaning solution, contact the manufacturer or local distributor.

In case of black-out, once the power is back the device will restart automatically.

Introduction

MSL 8 is able to stir up to 8L. Due to the new brushless motor, the stirrer stays cold even after several days of continuous operation. This feature makes it particularly appreciated in microbiology and biochemistry. Epoxy painted metal structure, with stainless steel cover, is studied and tested in order to give to the instrument an excellent resistance to the attack of chemical agents and to corrosion in general.

The stirring speed can be set within a range of 40 – 1500 rpm using the knob on the front panel.

NOTE: it’s important to choose the most suitable magnetic stirring bar related to the quantity and the liquid to be stirred as well as to the type of the beaker.

Assembly and installation

• Unpacking
  • Check the integrity of the unit after unpacking.
• The box includes
  • MSL 8 magnetic stirrer
  • Instruction manual
  • Plug for power supply
  • Switching VELP 100-240V/12V without plug

Stirring|

• Adjust speed set point by turning the speed control knob.
• Speed increases until set point is achieved.
• A microprocessor ensures constant speed (counter-reaction).
• Switch off the stirring by turning the knob to zero position.

Maintenance

Maintenance|

• No routine or extraordinary maintenance is necessary;
• Repairs must be carried out by authorized Velp personnel only;
• Instrument must be transported in its original packaging any indications present on the original packaging must be followed (e.g. palletized);
