Reliable Oxygen Measurements Continuous dissolved oxygen (DO) measurement is critical during fermentation and cell culture.

The InPro 6860i HD Anti-Bubble™ Oxygen Sensor is mechanically modified with a hydrophilic surface and a tilted tip design to prevent bubble accumulation, therefore creating a highly stable measurement signal.

The main cause of signal noise found in fermentation and cell culture is air or oxygen bubbles from the sparger that accumulate on the DO sensor’s tip. This creates a noise floor that is difficult to eliminate. Productivity, batch-to-batch consistency and product quality can all be adversely affected. InPro 6860i HD stops bubbles from adhering to the sensor: no bubbles – no noise.
