FAQ

What materials of the circulating bath come into contact with the bath liquid?

The wetted parts of the instrument are all 300 series stainless steel.

 

I would like to perform a heating / cooling program where the temperature ramps from one set point to another over time. Are the PolyScience 75 L Refrigerated & Heated Circulating Baths capable of this?

That depends on the controller used. Only the Advanced Programmable and Performance Programmable controllers can be programmed to perform ramps.
