Description
2.1 Designated use
This laboratory stirrer with glass-ceramics heating zone has been designed for the stirring of liquids in a
vessel while heating them up.
Using the appliance for other purposes is considered contrary to its designated
use and is inadmissible since this may result in unpredictable risks!
2.2 Scope of supply
For the scope of supply of your laboratory stirrer please refer to the accompanying packing list. If any parts
are missing or some damage can be noticed from outside, please contact the manufacturer or the sender.
2.3 Accessories
An optional temperature sensor is available for your laboratory stirrer. In addition, your stirrer has been
constructed so that it can be mounted on a tripod rod (available as accessory part incl. fastening nut,
see "6 Accessories").
2.4 Scope of functions
Laboratory stirrer SLR with two
control knobs and display
2.5 Warning and safety information
The inappropriate use of technical equipment always involves possible hazards to safety. Therefore:
The laboratory stirrer must only be operated by laboratory personnel especially
trained for this purpose and familiar with all precautionary measures required for
working in a laboratory!
When using this laboratory stirrer, all prescribed precautionary measures required for working in a laboratory
must be observed (in particular all applicable legal regulations relevant to accident prevention)!
The heating zone can heat up to a maximum temperature of approximately 555 °C! Therefore:
CAUTION! Risk of deflagration, explosion and fire hazard when heating flammable
liquids! Always heat up liquids with a flash point above 580 °C!
Be aware of increased ease of ignition of hot liquids!
Always cover vessel to prevent hot liquids from getting into contact with the heat-
ing zone (e.g. by liquid splashing or boiling over, or through escaping gases)!
The laboratory stirrer must be set up and connected in a way that ensures maximum safety for people and
material handled (see "3.1 Setting up and connecting")!
Stirring rate and heating output of the device can be sensitively
regulated by means of two control knobs and a display for control
purposes.
If precise temperature control is required, we recommend to operate
the stirrer with a temperature sensor (accessory). This sensor is
used to control the temperature instead of the heating output. If a
sensor is connected, the display alternately shows the selected
command temperature and the actual temperature measured for the
heated medium instead of the heating stages.
