G400 Gas Mixing System

G400 Gas Mixing Systems

Qubit Systems’ G400 Gas Mixing Systems can provide any gas mixture for up to 9 different gases. Highly accurate gas blending from ml to hundreds of Litres is provided by a single system. Gases are mixed automatically using Mass Flow Controllers with superb accuracy. Our PC-based Gas Mixing Software (C960) performs all the calculations required to generate your chosen gas mixture and implements mass flow controller settings with a mouse click.

Users may program a series of gas combinations and timings. If any selection is out of range the software warns the user.  Each mass flow controller comes with calibrations for 130 different gases or gas mixtures.  These may be changed in software as requirements change. Contact QUBIT with your specific requirements.  Let us know the number of gases, types of gases, concentration ranges of the mixtures and the total final flow rate required, and we will design your Gas Mixing System.

QUBIT’s G400 Gas Mixing Systems are used to supply specific gas mixture in bioreactors, multicultivators, incubators and growth chambers.  One Gas Mixing System may supply gas to multiple units.
