3 INTENDED USE OF THE UNIT
Laboratory shaker is destined for stirring biological or chemical materials contained in beakers, flasks, probes,
plates, micro cover glasses and cuvettes.
The unit can be used whenever continuous stirring of the probes is required:
WR tests
latex agglutination
yeast and bacteria culture tests
immunological and biochemical reactions tests
etc.
Electronic control system provides thorough rotational speed regulation of the shaker's plate with constant ampli-
tude. It enables to specify work parameters adequate to carried out test.
4 BEFORE FIRST OPERATING
The unit is sent in a cardboard box. It is necessary to transport it in the upright position and prevent it from any
unintended movements.
Once you receive the unit, please check its technical condition and all accessories. Any claims
regarding latent defects should be reported to the manufacturer, while any damage during
transport or incomplete accessories need to be passed to the entities who are responsible for the
transport and unloading.
The unit should be used in a place that fulfils following conditions:
ambient temperature 10°C do +40°
relative humidity: to 70% (or up to 95% under conditions which do not allow to condensation)
the unit should not be exposed to direct contact with sunrays/solar radiation and should be placed
far from a source of heat
the unit should not be used in the environment where a great dustiness occurs
the unit should be installed in a tough and stable surface
the unit should be put in a position that guarantees easy flow of air around the unit, i.e. the walls of
the unit are 50 mm away from the wall.
The unit uses alternating current 220-240V/50Hz. It should be connected to a wall socket
equipped in grounding to avoid electric shock in the case of the possible shaker damage.
