The Labmart RCB620T Refrigerated Circulating Bath is a horizontal temperature-control system designed especially for viscometers and other laboratory instruments requiring controlled circulating liquid temperature. It provides a –20°C to 100°C temperature range, ±0.05°C accuracy, 0.01°C resolution, 6L bath capacity, 6 L/min circulation flow and microprocessor PID control.

Product Overview

The RCB620T Refrigerated Circulating Bath is a temperature-controlled circulating bath with a horizontal configuration specifically designed for applications where controlled liquid temperature is required. Its horizontal design allows a viscometer to be attached on top, making it particularly suitable for viscosity measurements requiring temperature control.

The system uses air-cooled compressor refrigeration with R-134A refrigerant, a PT100 temperature sensor and microprocessor-based PID temperature control. It supports both internal and external pump circulation with a specified pump flow rate of 6 L/min.

The 6-litre bath features a stainless-steel inner tank, touchscreen operation, overheat protection and a water-level alarm. The supplied design also incorporates fast cooling, low noise and low vibration operation.
