Manufacturer: Thomas Scientific Instruments Co., Ltd.
Model: TRL-70SLP

By employing a dual-stage refrigeration system, it is possible to circulate ultra-low temperature liquid at -70°C to the outside.

• Cooling capacity: Minimum operating temperature -70°C, with a cooling capacity of 350W (when liquid temperature is -50°C).
• The circulation pump, which is also used for agitation, is a 60W motor-driven, seal-less pump that can be used safely for extended periods. The pump has a maximum head of 3m, a maximum flow rate of 15L/min, and a maximum discharge pressure of 0.03Mpa.

Usage example

It is used for low-temperature testing and storage of samples, indirect cooling of low-temperature containers, and as a stable cooling source as an alternative to dry ice.
