Artificial rumen simulation system

1、 Equipment usage

The artificial rumen dynamic simulation fermentation system is widely applicable in microbial laboratories of research institutes and enterprises, and is an ideal tool for studying the digestive system of ruminants. It is an important means for studying rumen digestion and metabolism in vitro.

2、 Main structure of the system

Simulator structure: volume 0.25L, ex situ sterilization, design pressure 0.3Mp; simulator has automatic pressure relief function and dedicated exhaust hole for gas phase analysis. The simulator comes with an adapter structure that can adapt to different volumes and quantities of simulators, providing flexible matching. The adapter motherboard can be replaced and can be expanded to other volumes or even more simulators.
