Circulating Baths

	Quality Circulating Baths Provide Accurate, Dependable Results—Whatever Your Need Cole-Parmer® PolyStat® heating and cooling circulating baths are available in multiple configurations to deliver the ideal combination of precision, versatility, and repeatability for your requirements. The next generation of circulating baths feature touch-pad setting, making it easier to adjust the temperature to your requirements. Enhanced controller and temperature sensor ensure accurate and repeatable readings. In addition to circulating baths, the PolyStat line includes immersion circulators that make it easy to convert any water bath into a circulating bath. Guarantee Accurate Results and Repeatability Unlike still baths, constant circulation systems deliver uniform temperature control to improve stability. Still baths tend to heat from the sides and bottom, causing fluid near the heating element to be warmer than that in the center. Circulating baths continuously move the fluid, making sure there are no variations in the temperature. Gain More Functionality from a Single Circulating Bath Versatile PolyStat circulators offer you more options than still baths, including the ability to cool or heat external applications. The 1/4" rear fittings allow you to connect tubing so cooled/heated fluid can be pumped to your external applications, such as a rotary evaporator.


	Polystat Circulating Baths These robust circulators feature a long-life, highwattage heater that allows you to easily convert an open bath into a constant temperature bath. Analog Circulator features a PID temperature controller with high-temperature and low-level cutoffs to protect the application from accidental heater overrun, protecting your samples and equipment. High-wattage heater provides fast heat up without scorching bath fluids. Set temperature from 25 to 100°C with manual dial. Directable nozzle lets you set the direction of pump flow to maintain uniform temperature and ensure effective mixing. Use screw clamp to attach circulator to any bath wall up to 1" thick. Digital Circulator lets you set temperature from 25 to 200°C with the touch-pad controls. Primary LED display shows set point or actual temperature with the touch of a button. Secondary LED display shows fault code whenever circulator automatically cuts off. Directable nozzle lets you set the direction of pump flow to maintain uniform temperature and ensure effective mixing. Use screw clamp to attach circulator to any bath wall up to 1" thick.
