WHY HAVE MY CALIBRATION TIPS CHANGED ?

The tips shall be disinfected and autoclaved. (134 °C during 20 minutes, each tip has a validated lifespan for 100 autoclaving cycles).

Please check regularly the quality of the internal surface of the tip. Its grey color should be mat and not shiny. The grey coating acts as a calibration chart (white balance).

If it is degraded, the calibration will be affected and the results potentially erroneous.
