EziLab's Refrigerated Circulator Bath EZL-RB152 heats and cools a 22 liter tank from -20C to 200C using a PT-100 sensor, PID auto-tuning control, and a 7 liter-per-minute external circulation pump that moves conditioned fluid out to connected glassware or test cells. Programmable memory for up to 10 segments automates multi-step profiles, while over-temperature protection, leak detection, and low-noise operation support unattended overnight runs. A 1.5 kW stainless steel heater and air-cooled refrigeration handle both heating and cooling within one circulating bath. As a viscosity bath built for ASTM-style kinematic viscosity work, this unit holds petroleum and lubricant samples at exact test temperatures during timed flow measurements. Materials testing and quality control labs use the wide range for freezing point determination and reaction temperature control during synthesis work, while pharmaceutical and biotechnology teams rely on the same constant temperature bath for reagent conditioning ahead of assays. Academic research settings apply this laboratory water bath to a mix of teaching and applied projects needing both sub-zero and high-temperature stages. Petroleum labs running viscosity grades favor a heating and cooling bath like this one to cut changeover. See the Refrigerated Circulator Baths and Refrigerated Circulator Bath pages for further specifications and ordering details.
