Heating circulators in the lab

With a laboratory circulator from the heating circulators category, samples in test tubes, Erlenmeyer flasks or other vessels can be precisely heated and maintained at the desired temperature. The units are designed for high transfer efficiency and the best possible temperature homogeneity. The adjustable setpoints are above the ambient temperature. For laboratory circulators with an integrated pump, external applications can also be temperature controlled.

Refrigerated circulators in the lab

A laboratory circulator with cooling machine can bring samples and applications in the laboratory precisely to a predefined temperature over a wide working temperature range and keep them there constantly. The cooling machine, whose operating principle is very similar to that of a usual refrigerator, also allows temperatures below the ambient temperature. This makes the units very flexible to use and enables temperature control applications in a very wide range of industries.
