Description
The PolyScience MX20R‑30‑A11B combines precision, performance, and usability in a 20 L refrigerated circulator. Powered by an integrated refrigeration unit and intuitive MX controller, it maintains ±0.01 °C stability across −30 °C to 30 °C, ideal for demanding sub-zero applications.
Key features include a stainless-steel reservoir with insulated lid, rear drain valve, and 20 L/min circulation pump. The 3.25″ LCD offers clear controls and status display. Safety protections include low-liquid and over-temperature shutdown. This unit is well-suited for QA labs, viscosity studies, and materials testing under sub-zero conditions.
