VWR Vwr Ad 20l Heating Circ 240v Unit EA. The heater circulator has been designed to eliminate exposure of samples to the environment being tested via direct immersion or by use of a water cooled immersible probe. A three-digit numbered port allows access to the heating vessel and enables users to easily view and change the setpoints. The H20H200 circulator is fueled by an easily accessed 20-AA battery pack (user must purchase adapter kit 89202-944 see ordering information on back of door). An automatic stop valve on the circulation circulator valve at the hemispherical circulator keeps the tube from overheating to protect the sample. The tubing clamps onto the heating circulator bringing the total amount of liquid to 20L. The circulator then has the ability to heat the sample in the presence of a frozen sample or by re-gassing the sample. Capacity: 20L Method: Admixtured dilutent/animic control system.
