The ZZKD DCW-0508L is an 8L circulator bath that combines refrigeration and heating with an integrated magnetic stirring system. Stirring speed is adjustable from 0 to 1000 rpm, allowing samples to be agitated directly inside the bath without a separate overhead motor.

The unit covers a temperature range of -5/-10/-20/-30 to 100°C with a display resolution of 0.01°C and stability of ±0.05°C. A PT100 sensor and PID control manage temperature, and a hidden cooling coil preserves usable tank space. Both inner and outer loop circulation are supported for connecting external apparatus.

It is suited to laboratories that need precise thermostatic control with simultaneous stirring of small reaction vessels, including those as small as 100 mL.

How It Works

A hermetic compressor provides refrigeration while integrated heating elements (1–2.2 kW) supply heat, with a PT100 sensor and PID logic holding the setpoint. A built-in magnetic stirrer rotates a stir bar inside the vessel to keep the bath medium and sample at a uniform temperature, and inner or outer loop circulation distributes the controlled fluid as needed.
