Tips to Improve pH Measurement

Accurate pH control is fundamental for a wide variety of industrial bioprocesses. Some of those processes are based on cell or microbial cultures where the pH value has to be kept within a narrow range. This video shows the three most helpful tips to ensure optimal growth and product yield.

Accurate pH control is fundamental for a wide variety of industrial bioprocesses. Some of those processes are based on cell or microbial cultures where the pH value has to be kept within a narrow range. This video shows the three most helpful tips for maintaining glass membrane pH probes to ensure optimal growth and product yield.

Topics within the video:

  • pH sensor lifespan considerations (Nernst Equation, slope and zero point offset, process conditions)
  • Sensor calibration (Selecting pH buffers, temperature considerations)
  • Care and cleaning of the glass membrane and liquid junction (Best practices)
