Ruminant & Monogastric Fermentation - Model Gas Endeavour - In vitro Digestibility Test System
Gas Endeavour® is our premier automatic instrument for continuous monitoring of fermentation gas (i.e., hydrogen, methane, carbon dioxide) released in in-vitro ruminant digestive models and in-vitro monogastric hindgut digestive model for monogastric animals and human. In comparison with the other in-vitro methods measuring the transformation of fermentable substrate, the Gas Endeavour® allows highly accurate analysis for a large number of samples in a short time. The automated in-vitro protocol based on the Gas Endeavour® significantly reduces the workload compared with manual analyses.
