Applications

Laboratory Research

Ideal for chemical synthesis, sample incubation, and biological assays where precise temperature control is critical.

Quality Control

Used extensively in pharmaceutical and industrial labs to ensure consistency and reproducibility in testing processes.

Industrial Testing

Suitable for viscosity measurements, material testing, and any process requiring stable thermal conditions.

For comprehensive thermal management in laboratory and industrial process control, consider pairing the Heated Circulator 20 Liters SD with complementary temperature regulation solutions such as the PolyScience Refrigerated Circulator 20 Liter –30 °C, which offers reversible cooling and heating for applications demanding sub‑ambient control and precise thermal stability across extreme temperature ranges. When your workflow requires integrated temperature control with advanced MX series functionality, the 15 Liter Refrigerated/Heating Circulating Bath with MX Temperature Controller delivers versatile performance, adaptable to both heating and chilling with user‑adjustable limits and alarms. For compact benchtop applications where temperature stability and uniformity are critical but space is limited, the Digital Water Baths provide precision thermal control across multiple reservoir sizes, ensuring consistent temperature conditions for incubation, inactivation, and routine analytical processes.
