The MTST GDX 10L is a combined heating and cooling temperature circulator that brings low-temperature cooling and high-temperature oil bath functions into a single unit. It operates across a temperature range of -20 to 199°C with a 10 L reservoir capacity, making it suitable for laboratory processes that require both chilling and elevated-temperature control.

The system uses a sealed, closed liquid loop with an expansion vessel that is mechanically isolated from the circulating fluid. This design helps prevent water vapor uptake at low temperatures and oil mist intake at high temperatures, supporting stable operation across the full range.

It is intended for use in academic, environmental, biochemical, medical, chemical, and general research laboratories that need integrated temperature control with continuous circulation.

How It Works

A single circulating loop moves heat transfer fluid through an integrated heating and cooling container with a large heat exchange area. A 100 W pump delivers up to 20 L/min flow with a 6 m lift, while the heating element (2000 W) and refrigeration system (920–2150 W cooling capacity) regulate fluid temperature. The loop is sealed and connected to an expansion vessel that stays below 60°C and does not circulate with the working fluid.
