Features on all Polyscience Heated Circulating Baths


  • Whether equipped with the entry-level MX
  • Controller or the most sophisticated Performance
  • Programmable, our Heated Circulating Baths are extremely easy to use. Crisp menu architecture, screen icons, and plain-text prompts make it easy to navigate through operational settings and options.


LidDock™ helps keep moisture where it belongs — in the bath. And accessing the reservoir drain is as simple as removing the Circulator’s front panel.


All models feature user-settable high-temperature safeties as well as redundant over-temperature protection and comply with RoHS, WEEE, IEC 61010-1, IEC 61010-2-010, IEC 61326-1, DIN 12876 and are CE and ETL certified. Our DuraTop™ surface is cooler to the touch when operating at high temperatures.


Exceptionally exacting temperature control, combined with a tap-water cooling-coil, allows you to maintain bath temperatures at or near ambient with stabilities as precise as ±0.005°C.


A variety of communication and control options, including Ethernet, USB data logging and computer control, bi-directional serial communication, and external circulation with remote temperature control, enhance functionality and application flexibility.


Easy-to-use calibration function allows you to adjust the temperature display to match that of a traceable temperature standard.A highly intuitive operator interface makes changing the temperature set-point or making other operational adjustments simple and straightforward.
