Gas Extractors

Gas Extractors - Grease & Oil 


The GasExtractor is a fully automated vacuum degassing unit for extracting gas from oil and other highly viscous liquids according to international standards. The determination of the total gas content is performed by fast and precise determination of the pressure increasing.


The GasExtractor provides the basis for identification of gas compounds and can be linked easily with standard gas chromatographs.


The GasExtractor is equipped with a powerful four stage membrane pump. The vacuum can be generated without mercury (substitution of Toepler pump). The system can be upgraded with an autosampler for different sizes of syringes for oil samples.
