The -30 °C Thermostat Circulating Water Bath is designed for precise low-temperature laboratory experiments and temperature-controlled processes. It is widely used in scientific research, biology, physics, pharmaceutical laboratories, and chemical industry applications where stable and accurate temperature control is required.

This circulating bath provides a temperature range from -30 °C to 99 °C with high accuracy of ±0.1 °C, allowing both cooling and heating functions within a single unit. It can replace traditional cooling methods such as dry ice or liquid nitrogen for many laboratory reactions, providing a safer and more convenient alternative.

The system can also function as a low-temperature bath for viscosity testing or as a temperature control source for external laboratory equipment. A stainless steel tank ensures corrosion resistance and durability, while the optional dual-stage magnetic stirring system helps maintain uniform temperature distribution throughout the bath.

With built-in safety protections and optional PLC automation with programmable control, the unit delivers reliable and stable performance for demanding laboratory and research environments.
