LAUDA Alpha

Heating and cooling thermostats for cost-effective thermostating in the laboratory at temperatures from -25 up to 85 °C

LAUDA Alpha is the cost-effective choice in the area of high-quality LAUDA thermostats. The temperature range from -25 to 85 °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

	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 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

The heating thermostats A 6, A 12 and A 24 operate in the temperature range between 25 and 85 °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 85 °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.
