Residual protein left on the surface of instruments could interfere with the effectiveness of sterilisation procedures.
In essence the instruments are still “dirty”.
Good hygiene practice involves the use of ultrasonic cleansers and washer disinfectors prior to autoclaving. However it is important to test the efficacy of the cleaning of these machines.
Some ultrasonic cleansers have “sweet spots” in the tanks where they clean well – but the quality of cleaning may not be uniform throughout the bath. We have test kits that allow you to assess the efficacy of the whole ultrasonic bath unit (contact us for details).
In addition we have specialist testing kits to detect low levels of residual protein remaining on instruments after cleaning. Click Here for more details.
