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 45 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.   It is possible to have the circulation on without any temperature control being on? No. If the circulation is on, then a temperature setting must be selected.
