pH Meter

  • Turn on with the probe still in storage solution
  • Remove pH electrode from the storage solution and rinse it with ddH2O into a waste collection container
  • Measure pH; take care not to allow the probe to bang into the wall or rim of your test tube
  • Rinse again after use
  • Replace probe in storage solution before turning off; never store electrode in water or in a buffer solution of pH ~ 7
  • Empty the rinse waste collection container and clean up before leaving
