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. The instrument must be
transported in its original packaging and any indications present on the
original packaging must be followed (e.g. palletized).
It is the responsibility of the user, to properly decontaminate the unit in
case of hazardous substances remaining on the surface or interior of the
device. If in doubt about the compatibility of a cleaning or decontamination
product, contact the manufacturer or distributor.
Cleaning
Disconnect the unit from the power supply and use a cloth dampened with an non-inflammable non-aggressive detergent.
