Măsurarea și controlul al debitului de gaz

Măsurarea și controlul al debitului de gaz

Special conceput pentru folositrea cu bioreactorul sau fermentatorul LAMBDA.

Spre exemplu, permite controlul pH-ului culturilor celulare prin aditie controlata de CO2, controlul oxidenului dizolvat prin reglarea debitului. Poate fi de asemenea folosit independent, din moment ce toate functiile pot fi controlate din panoul de control.
