Techne Dip and Flow coolers are designed for use at below ambient temperatures down to -35°C.
The Flow Coolers work in conjunction with a Techne thermoregulator (excluding TU-20HT). They continually extract heat from the bath fluid by means of the heat exchanger which is built into the unit.
The cooling head of the Techne Dip Coolers fit neatly and unobtrusively into the corner of the standard circulating bath and can be secured with a specially designed mounting bracket. Even if cooling can be achieved by cold tap water, a dip cooler is recommended as it conserves water and is easier and more convenient to use.
