The PolyScience SD20R‑30‑A11B delivers precise sub-zero capability within a mid-size 20 L refrigerated circulator. It maintains ±0.01 °C stability across −30 °C to 30 °C, thanks to an integrated, powerful refrigeration unit.
Its stainless-steel reservoir features an insulated lid, rear drain valve, and high-flow circulation pump (~20 L/min). A color LCD panel enables easy control and monitoring. Built-in safety systems (low-liquid and over-temp shutdown) protect sample integrity. Ideal for sample prep, QA checks, viscosity studies, and other cold-range applications in labs.
