Gas Mixing Station, FS-O-GM


The Winpact Gas Mixing Station allows you to optimize cell growth condtions by independently supplying up to four gasses to the fermentation process. Parameters such as dissolved oxygen and pH can be controlled by adjusting the gas composition supplied to the system. Four manually adjusted flow meters control the flow rate of each gas, while the 4 solenoid valves automatically open or close in response to the culture conditions.

  • Perfect for cell cultivation
  • Blend air, oxygen, carbon dioxide and nitrogen in any proportion to optimize cell growth
  • Adjust pH using carbon dioxide; avoid media dilution by addition of liquid acid
  • Control DO by addition of oxygen gas and nitrogen gas
  • User specificied gas flow rate for individual gas
  • Operated under manual or automatic mode
  • Integrated with DO cascade for precise DO control
Control gases Air, N2, O2 and CO2
