4.4 Steam sterilisation
Steaming has the advantage that it does flushing, cleaning and sterilisation in one operation. However
the heat from the steam will cause sugary substances to caramelise and substances containing protein
to coagulate and burn; see chapter 2.1. In this case flushing with an appropriate fluid must precede post-
sampling steaming.
If steaming is the preferred procedure, but no steam is installed near the sampling point, an option is
to use a portable steam generator. Keofitt supplies an adapter for a Kärcher steam generator as well
as other mobile steam supply systems. The steaming process with a Keofitt sampling valve has been
validated to obtain sterility after 1 minute of steaming at 121° C (1 bar(g)). Documentation is available at
the Keofitt Online Service Center on www.keofitt.dk.
4.5 Sampling
Once the cleaning/disinfecting/sterilising is accomplished taking a sample is done by opening the valve
and closing it again once the require sample volume is obtained.
For detailed operator instructions see chapter 5.4.
