Stand-alone gas mixing device.

Description
The Kuhner FlowCon has been developed for the R&D environment and the initial production steps in bioreactors with disposable bags. Whether stabilizing the pH in cell cultivations with CO2,or reducing oxygen concentration for microaerophilic organisms the FlowCon gas mixer meets all user needs. The FlowCon can be used as a stand-alone device, or can be integrated with the Kuhner equipment family (incubator shakers, disposable bioreactors, …).

Reproducibility
Up to four mass flow controllers ensure high accuracy and reproducibility of the gas mixture. The number of mass flow controllers can be adapted to individual requirements (FlowCon 2/3/4). An integrated pressure sensor prevents overpressure in the connected bioreactor, by reducing the gas flow in the first step and shutting off the gas flow in the second step. Step limits can be freely programmed by the user. Integrated air filters and back pressure valves ensure a long interference free operating time of the FlowCon.
The Kuhner ISIS software provides: data logging, programming and controlling. Technical controls for “21 CFR Part 11” compliance are built in to ISIS-X software.
