100 ml of sample is distilled off in an open flask in an atmosphere with nitrogen during a pre-programmed heating time. The evaporated sample passes through a water-cooled condenser. The volume of condensate is measured in a graduated receiver by means of a differential pressure measuring system with density compensation at predetermined (programmable) points of the percent recovered (volume distilled).

For light products, an explosion-proof circulating cooling system is used to keep the sample inlet temperature and condenser temperature below the initial boiling point.

For heavy products, the condenser temperature is kept in proportion to the boiling range in order to avoid line plugging. The sample in the flask is mixed with nitrogen, thus reducing the risk of slowing down the distillation, ensuring rapid and homogeneous heating of the sample and reducing coking at the bottom of the flask. Low pressure measurement option is available.
