Circulation chillers for reliable continuous operation in the lab and in research from -10 up to 40 °C
The LAUDA Microcool product line has been designed as a circulation chiller line with four compact models and cooling capacities from 0.25 to 1.2 kW. The user interface with large LED display and the membrane keyboard make the devices easy to use. An RS-232 interface and alarm contact are integrated as standard.
What is unusual in this price category of circulation chillers is the high-quality block pump with magnetic coupling. The magnetic coupling of pump and electric motor exclude sealing problems on the pump shaft. LAUDA Microcool circulation chillers are used wherever heat needs to be dissipated reliable and fast, e. g. in laboratories for rotary evaporators, distillation systems or analytical devices.
Application examples
- Cooling of rotary evaporators
- Cooling of distillation systems
- Supply of cooling traps
- Cooling of analytical devices

Microcool Circulation chiller with cooling capacity of 250 Watt
The compact design MC 250 model makes it ideal for being positioned on the benchtop. The circulation chiller is equipped with a magnetic coupling pump. This supplies a pump pressure of 0.35 bar and a maximum pump flow of
16 L/min.
Microcool Circulation chillers with cooling capacities of
600 and 1200 Watt
The 600 and 1200 Watt cooling capacity models are floor standing instruments designed to fit underneath the lab bench. They are equipped with a pressure gauge to display the pressure and casters which can be controlled and locked. Pump pressure can be controlled via the integrated bypass. At 1200 Watt, the most powerful device is also available in a watercooled version as the MC 1200 W.
