O₂-Control

Essential O₂ regulation for stem cells

A reliable control of O2 is essential for cultivating cells (proliferation and metabolism of stem cells) and microorganisms with low/no oxygen demand. The O2 controller reduces the O2 level from ambient (20.95% at dry air; normoxia) to approximately 0% O(hypoxic). A digital PID controller adjusts the N2 flow rate to maintain the desired O2 value.
