Heating & Cooling Circulator (All-in-One)
One GDX unit does both heating and cooling: covering -20/-40/-80°C to 200°C with a fully sealed fluid circuit — no oil smoke at high temperature, no moisture absorption at low temperature. The ideal partner for precise temperature control of jacketed glass and stainless steel reactors.
