Techne manufactures a comprehensive range of general purpose water baths. Twenty different water bath combinations allow the use of accurate temperatures from -40°C up to 200°C; ensuring a solution for most laboratory applications. If sub-ambient temperatures are required it is necessary to add a cooling mechanism to the bath. Techne recommends the use of a Dip or Flow Cooler for temperatures down to -35°C. For example, the RU-200 can lower temperatures down to -20°C. It is also possible to use the cooling coil with a water supply for temperatures from 5°C above the water temperature to ambient.

Unheated baths are designed to be used with a clip-on Tempette or Tempunit thermoregulator, these baths are equipped with carry handles for added safety. All baths have stoved enameled steel outer cases and are supplied with bridge mounting plate to hold the thermoregulator. Polypropylene sphere can be used to create a ball blanket so as to reduce evaporation and heat loss, while proving instant access to the bath.

First select the unheated stainless steel bath (see chart below) which has the appropriate volume for the application, for example B- 26 which has a volume of 26 liters.Then add a thermoregulator (see 'Thermoregulator' sub-category within the 'General Lab Equipment' category) suitable for the required temperature range, for example the TE-10-D Tempette is a digital thermoregulator for temperatures between -40°C and 120°C. Select any accessories that are required, for example, both gabled and flat lids are available for all bath sizes. Gabled lids particularly allow tall tubes to be accommodated.
