This GMS instrument comprises four mass flow controllers to deliver a highly accurate flow of O2 (0.01 – 100%), CO2 (0.03 – 6%) and N2 gasses. An intuitive software interface allows for standard and custom protocols making automated operation easy and flexible. Exceptional precision in oxygen level is achieved by dedicating two mass flow controllers to regulating low and high oxygen flows, respectively. The GMS requires very little bench space in the lab due to the compact design. It includes dedicated software for Windows and is fully compatible with the Blood Oxygen Binding System (BOBS™).
