LAUDA Alpha is the cost-effective choice in the area of high-quality LAUDA thermostats. The temperaturerange from -25 to 100 °C covers the larger part of all basic thermostatic applications withinthe laboratory. This is exactly the working temperature range of the new LAUDA Alpha. This well-pricedequipment range is made possible by minimizing any unnecessary features, with the focus on reliabilityand user-friendliness.
The thermostats are suitable for operation with non-flammable liquids (water, water/glycol) and forboth internal and external thermostating tasks. A 1-point-calibration of the thermostats canbe carried out by the user.

Alpha Immersion thermostat
The immersion thermostat A can be used for any bath with a wall thickness of up to 25mm by means of the screw clamp included in the scope of delivery. Using the optionalpump circulation set and a cooling coil, the immersion thermostat can be expandedto form a full-fledged thermostating system.
Alpha Heating thermostats
The heating thermostats A 6, A 12 and A 24 operate in the temperature range between 25and 100 °C. As in the case of the immersion thermostats, a cooling coil and pumpcirculation 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 coolingperformance through the entire temperature range of -25 up to 100 °C. A drain connectionon the rear side of the devices makes emptying the heat transfer liquid a simplejob. Bath covers and pump kits are included in the standard equipment.
