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 DIGITAL instruments are able to stir up to 8, 25 and 50 L.
Thanks to the new brushless motor, the stirrer stays cold even after several days of continuous operation.
Speed Servo technology maintains constant speed as viscosity changes.
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 using the frontal knob within a range of 40 – 1500 rpm or 20 – 1000 rpm depending on the model.
The stirrer display shows the speed set point.
The instrument is equipped with advanced functions as auto-reverse of the stirring direction, intermittent mode programs and integrated timer to meet users’ workflow and safety lock feature to avoid possible alteration of the working conditions.
Introduction
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.

Installation

Unpacking
- Check the integrity of the unit after unpacking
The box includes
- MSL digital magnetic stirrer
- Instruction manual
- Plug for power supply
- Switching power supply 100-240 V / 12 V
Installation
- Place the unit on a non-flammable surface
- Make sure that the technical specification of the unit and the power supply line are the same
