Fermenter 20 L

DESCRIPTION

 

This pilot makes it possible to carry out a reaction calling upon micro-organisms

Apparatus sterilizable by introducing vapor into the fermenter

One will work in batch, at controlled temperature, a degasification and a ventilation are envisaged

The fermenter is an engine perfectly agitated and instrumented.

The unit of fermentation is delivered complete, instrumented with a technical handbook and practical work.
