Description
The PolyScience MX Series Immersion Circulator (MX21) delivers professional-grade thermal control from –5 °C to 150 °C with exceptional ±0.05 °C stability, making it ideal for applications like chemical reactions, sous-vide cooking labs, instrument calibration, and protein assays.
Its powerful variable-speed pump (up to 12 L/min) efficiently circulates liquid to maintain even bath temperature. The user-friendly digital interface displays set-point and actual temps, with soft-touch buttons for adjustments and a timer feature.
Compact and rugged, the MX Series mounts to tanks with a clamp system and supports both metric and imperial units. Safety features include automatic low-liquid shutdown and over-temperature protection.
