Dear Soukya,

depending on the scale (lab, pilot or industrial) usually Pt100 thermometers and electrochemical combination pH glass electrodes are used in bioreactors.

• Temperature Probe: Bioreactors commonly use Pt100 or Pt1000 temperature sensors, which are platinum resistance thermometers offering high accuracy and stability at a range of temperatures typically used in biological processes.
• pH Probe: Standard pH probes in bioreactors are glass electrodes designed for autoclavable, in-line measurements, often with a gel or liquid-filled reference system to ensure stability and resistance to fouling.
• Sterilizable Probes: Both temperature and pH probes are usually sterilizable to withstand autoclaving or in-situ sterilization, ensuring aseptic conditions in bioreactors.
• Material Compatibility: Probes are made of corrosion-resistant materials (e.g., stainless steel, glass) to endure the chemical and biological environment of the bioreactor.
• Real-Time Monitoring: These probes allow continuous, real-time monitoring and control of temperature and pH, critical for maintaining optimal microbial or cell culture conditions.
