More About this Item

These compact calibration baths offer excellent stability over the entire temperature range. Use these baths for external circulation to maintain temperatures of samples in viscometers, photometers, refractometers, fermenters and other reaction vessels.

All models offer high pump performance and exceptional thermal stability from -35°C to 250°C. Add a flow cooler to the system to achieve temperatures down to -35°C. The water baths are fully insulated on all sides and base and are fitted with a cooling coil for connection to a cold water supply for use at temperatures around ambient.

An immersion circulator is required for liquid calibration baths to operate—order Cole-Parmer IC-300 series or other compatible immersion circulators separately.

Please Note: Effective June 2022, the Techne Liquid Calibration Bath Model number FBCAL12D has now been rebranded Cole-Parmer under Model number WBU-250-12. All the same great features and specifications, just with a new and improved look.
