LAUDA-Alpha Cooling Thermostats

Designed specially for cost-effective laboratory thermostatting, LAUDA Alpha Cooling Thermostats strike a great balance between performance and value. A working temperature range between -25 and 100°C allows LAUDA Alpha Cooling Thermostats to cover most of basic laboratory thermostatic applications. LAUDA Alpha Cooling Thermostats' exceptional cost-efficiency is achieved by minimizing unnecessary features, with more focus and user-friendliness and reliability.

Reliable technology, modern design, favorable price

LAUDA Alpha Cooling Thermostats are suitable to be operated with non-flammable liquids such as water and water/glycol, and for both internal and external thermostatting applications. LAUDA Alpha Cooling Thermostats are also equipped with the capability of 1-point calibration, and this can be carried out easily by the user.


LAUDA Alpha Cooling Thermostats are designed with cooling technology which enables exceptional cooling performance through the entire temperature range from -25°C up to 100°C. A drain connection on the rear side of the devices empties the heat transfer liquid. Standard equipment includes bath covers and pump kits.
