DW-YQ-2/20SJ DW-YQ-5/20SJ Low Temperature Cooling Circulator
The DW-YQ Series low temperature cooling circulator is designed to provide stable external cooling for laboratory instruments and temperature-controlled processes. With PID temperature control and continuous liquid circulation, it can be used with rotary evaporators, atomic absorption and plasma emission spectrometers, scanning electron microscopes, molecular distillation systems, Kjeldahl analyzers and other equipment requiring a circulating cooling source. For rotary evaporation, it supports cooling during concentration, extraction, drying, separation and crystallization workflows.
