Thermoregulators
Techne invented the "Clip On" thermoregulator in 1948 and now offers four "Clip On" units. Thermoregulators are designed to be used with the Techne, unheated water baths or any other suitable laboratory vessels. They will heat, circulate and safely control the temperature of the liquid in the bath within precise limits.

Cooling coil
Connects to the mains water supply; the water being circulated through the coil should be at least 5°C cooler than the set of the bath temperature.

Sub-ambient cooling
This thermoregulator can be used for sub-ambient cooling, right down to -40°C, although a low-temperature liquid is required below 0°C. Sub-ambient cooling can be achieved using the cooling coil accessory (part number FCC01) connected to an external chilling system, for example a cold tap. Alternatively a Techne dip-cooler or flow cooler could be used as a method of chilling.

External circulation
This thermoregulator can be used in several ways. (1) Stand-alone waterbath temperature controller with precision accuracy and stirring action. (2) Pump for recirculating chilled liquid produced in an external chiller allowing sub-ambient water bath temperature. (3) Pump for providing temperature control to an external system or device. (4) A combination of using externally chilled liquid and providing temperature control to an external system.
