Safety Regulations

The plug disconnects the instrument.
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.

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.

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 200 °C. Only small amounts (< 50 ml) of flammable liquid can be used with the device.

Introduction

MULTISTIRRER Digital is able to stir up to 6 beakers having a maximum diameter of 85 mm (MULTISTIRRER Digital 6) or up to 15 beakers having a maximum diameter of 64 mm (MULTISTIRRER Digital 15) at the same time.
Thanks to the brushless motors, the stirrer stays cold even after several days of continuous operation
Epoxy painted metal structure, with stainless steel cover, are 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 80 – 1500 rpm.
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.

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.
For MULTISTIRRER Digital 6 is suggested the stirring bar A00001056 (6×35 mm); for MULTISTIRRER Digital 15 the A00001057 (6×20 mm).

Installation

• Unpacking
  • Check the integrity of the unit after unpacking
• The box includes
  • MULTISTIRRER 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
  • Place the flasks containing the sample and a suitable magnetic stirring bar on the stirring plate
  • Connect the instrument to an easily accessible socket (compliant with the current safety norms), using only the provided power supply and dedicated plug

Operation

• Rotate the knob to set the stirring speed.
  Note: push the knob to stop stirring.

Autor verse, intermittent mode and timer functions

• While the display shows OFF, push the knob for 3 seconds.

• Rotate the knob to set the auto reverse time (minutes/seconds).
  The rotation direction will change after each set interval time.
  Note: select NNSS to disable the function.

• Push the knob. Then rotate it to set the run time of the intermittent mode (minutes/seconds).
  Note: select NNSS to disable the function.

• Push the knob. Then rotate it to set the pause time of the intermittent mode (minutes/seconds).
  The stirring function will be interrupted cyclically. The run time and the pause time should both be set.
  Note: select NNSS to disable the function.

• Push the knob. Then rotate it to set the timer (hours/minutes).
  After the timer has elapsed, the stirring will be stopped and the display will show End.
  Note: select HHnn to disable the function.
