General Information

Before using the unit, please read the following instruction manual carefully.

Do not dispose of this equipment as urban waste, in accordance with EEC directive 2002/96/CE.

This unit must be used for laboratory applications indoor only. The manufacturer declines all responsibility for any use of the unit that does not comply with these instructions. If the product is used in a not specified way by the manufacturer or with non specified accessories, product’s safety may be compromised.

This unit has been designed and manufactured in compliance with the following standards:

Safety requirements for electrical equipment for measurement, control and for laboratory use.

Electrical equipment for laboratory use UL 61010-1

General requirement – Canadian electrical code CAN/CSA-C22.2 No.61010-1

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.
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.
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 is able to stir up to 6 beakers having a maximum diameter of 85 mm (MULTISTIRRER 6) or up to 15 beakers having a maximum diameter of 64 mm (MULTISTIRRER 15) at the same time. 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 80 – 1500 rpm using the knob on the front panel. The Stirrer led shows when the stirring is running.
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 6 is suggested the stirring bar A00001056 (6×35 mm); for MULTISTIRRER 15 the A00001057 (6×20 mm).

Assembly and Installation

Upon receipt and after having removed the packaging, please check the integrity of the instrument. The box includes:

• Magnetic stirrer MULTISTIRRER
• Plug for power supply
• Switching VELP 100-240V/12V without plug
• Instruction manual

Electrical connection

After having unpacked the instrument, place the unit on the laboratory bench.
Before connecting the instrument to the power supply, make sure that the values on the rating plate correspond to those of the power supply. Connect the unit to the power supply using the transformer supplied.
Ensure that the socket and the relative cut-off device conform to current safety norms and easy to reach.

Start-up

Rotate the speed knob completely to the left. Place the flasks containing the sample and a suitable magnetic stirring bar on the stirring plate. Then, set the speed by turning the speed knob.

Operating controls

Turn the stirring speed knob on the front panel in order to start the stirring function.
It is possible to select speeds between 80 and 1500 rpm. When the led is lighted it means that the stirring is on.

Maintenance

No routine or extraordinary maintenance is necessary apart from periodically cleaning the unit as described in this manual. In compliance with the product guarantee law, repairs to our units must be carried out in our factory, unless previously agreed otherwise with local distributors.
