Thermostats
Heating and cooling thermostats for cost-effective thermostating in the laboratory at temperatures from -25 up to 100 °C
LAUDA Alpha is the cost-effective choice in the area of high-quality LAUDA thermostats. The temperature range from -25 to 100 °C covers the larger part of all basic thermostatic applications within the laboratory. This is exactly the working temperature range of the new LAUDA Alpha. This well-priced equipment range is made possible by minimizing any unnecessary features, with the focus on reliability and user-friendliness.
The thermostats are suitable for operation with non-flammable liquids (water, water/glycol) and for both internal and external thermostating tasks. A 1-point-calibration of the thermostats can be carried out by the user.
Application examples
- Sample preparation for chemico-pharmaceutical analysis
- Quality control
- Precise temperature control in sensitive areas such as medical serology
- Versatile thermostating tasks in the field of biotechnology

Easy cleaning of the cooling air intake by removing the front cover without tools.
3-button operation with large, clearly legible LED display – easy and intuitive menu navigation and easily legible display values
Integrated shut-down timer– automatically initiates stand-by mode for sample protection and reduced operating costs
Automatic compressor generates precisely the required cooling capacity – up to 425 W – cost-effective operation; no unnecessary energy consumption; equipment-saving principle extends the life of the compressor
Alpha immersion and heating thermostats with screw clamp – easy to change to different bath vessels
Variable flow rates via inserts and fittings – the rate of circulation can be adapted to the size of the bath
Removal of the front cover without tools – easy cleaning of the cool air inlet and extended maintenance intervals

Alpha Immersion thermostat
The immersion thermostat A can be used for any bath with a wall thickness of up to 25 mm by means of the screw clamp included in the scope of delivery. Using the optional pump circulation set and a cooling coil, the immersion thermostat can be expanded to form a full-fledged thermostating system.

Alpha Heating thermostats
TThe heating thermostats A 6, A 12 and A 24 operate in the temperature range between 25 and 100 °C. As in the case of the immersion thermostats, a cooling coil and pump circulation set as well as a bath cover set are available as optional accessories.

Alpha Cooling thermostats
The cooling technology of the cooling thermostats RA 8, RA 12 and RA 24 enables cooling performance through the entire temperature range of -25 up to 100 °C. A drain connection on the rear side of the devices makes emptying the heat transfer liquid a simple job. Bath covers and pump kits are included in the standard equipment.
