Description
This gas flow regulator was developed for laboratory bioreactors and fermenters. For example, it would allow pH regulation with CO2 in cell cultures. It is often used in cascade control systems. It is easy to use; a touch screen display allows for complete parameter settings. It can also be used independently for other applications.
A laminar mass flow sensor ensures precise measurement with minimal pressure drop. The gas flow is regulated by LAMBDA’s proprietary, microprocessor-controlled proportional needle valve.
Applications
- pH control in cell cultures with CO2
- O₂-enrichment and pO₂ regulation
- gas station for cell cultures , combining several MASSFLOW touch units to mix gases such as N₂, Air, O₂, and CO₂ with precision – ideal for creating defined gas compositions or adjusting specific concentrations.
