Cole Parmer WBU-250 Series Liquid Calibration Baths
The WBU-250 Series liquid calibration bath (LCB) series offer compact, accurate and reliable liquid water baths which can be used for external circulation or temperature calibration of thermal sensors.
When temperature calibration is required the compact liquid baths offer excellent stability over the entire temperature range. The LCBs can be also be used for external circulation to maintain temperatures of samples in viscometers, photometers, refractometers, fermenters and other reaction vessels.
All models of LCB offer high pump performance and exceptional thermal stability from -35 °C to 250 °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.
The minimum temperature achievable is -35 °C when a Flow Cooler is added to the system. Each bath is supplied complete with lid, drain tap, carry handles, a cooling coil (with bung) and hole to position a certified sensor.
Please note: for Liquid Calibration Baths to operate, a circulator is required. The circulator must be purchased separately with a variety to choose from.
