The Single-Use Electrode Corrugated Tube Assembly is designed for aseptic monitoring of pH, DO in biopharmaceuticals. It consists of corrugated silicone tubing, sterile quick couplings and PG13.5 threaded connector. It needs to be autoclaved in a sterilizing kettle at 121℃ for thirty minutes to one hour before it is put into use. Its black hand clamp cannot be autoclaved. The working of the sensor is guaranteed to isolate the sensor from external contamination such as stray bacteria by means of aseptic connectors.
