Laboratory External Circulator Bath

The external circulation constant temperature bath maintains temperature stability by pumping the constant-temperature liquid from the bath to external equipment. It is used for temperature control in laboratory reactors, viscometers, and other devices to ensure consistent testing conditions.
Selection
When selecting, consider the temperature range covering experimental needs, temperature control accuracy matching test standards, pump flow meeting equipment circulation requirements, material corrosion resistance suiting working fluids, and dimensions fitting the installation space.
