Description

AbsorptoMeter for running precise and reproducible absorption tests What does it measure? The Brabender AbsorptoMeter is a tabletop instrument with a torque measurement system (dynamometer), which is used for the precise and reproducible determination of the oil absorption number (OAN and COAN) of powdery materials. The test method is based on the changes of the consistency of powdery materials during oil absorption. Why is this important? The oil absorption number is widely used for characterizing the structure of carbon blacks and other free flowing materials which has a strong effect on the processing and vulcanization parameters and the quality of the product as well. How does this instrument work? The AbsorptoMeter consists of a drive unit with a torque measurement system and an attached mixer with special blades. The torque is measured and recorded throughout a special mixing process: the oil is gradually added by an automated buret into the mixer. The free flowing, powdery material absorbs the liquid and starts agglomerating. During this transition, more and more torque is needed for the mixing and eventually a torque peak appears on the time-torque curve. The OAN itself is given in accordance with the standards and common practice in ml (of the absorbed oil) / 100 g (of sample material). What are the benefits? - Automatic (sequencer controlled) buret with ready to use default settings - Easy to change mixing bowls reduce the dead time and eansure continuous operation - Easy to access buttons and touchscreen at the front of the instrument, direct connection to the PC via USB, easy cleaning - Low maintenance
