New products for hydrogen peroxide sterilization processes

New products for hydrogen peroxide sterilization processes

To get a better contrast gke has modified the indicator colour change from originally purple to pink now from blue to green.

For each chemical indicator according to EN ISO 11140-1, a so-called "Stated Value" (SV) according EN ISO 11140-1 is defined: “value or values of a critical process variable at which the indicator is designed to reach its endpoint as defined by the manufacturer” and must be specified. 

This requirement however is only possible to be carried out if there is a standard test method to test the chemical indicators. gke has offered to ISO a liquid test method which is currently in discussion. According to this method, which is available on our website, we have tested the type 1, 2 and 4 indicators providing an SV of 2, 4 and 6 min.

The SV is stated on each indicator, so that there will be no confusion.

The old package indicator version with the colour change from purple to pink has a SV of 6 min may be still available until the stock is empty.

The colour of the BMS strips for PCDs has been also changed and the SV is reduced to 2 min, while the old purple version had an SV of 6 min. The SV has been reduced because a lot of sterilizers could not pass the more difficult indicator strip.

Documentation labels with strong adhesion

Documentation labels with strong adhesion

gke offers self-adhesive labels in various dimensions for marking sterile goods packaging. The labels on roll are double-self-adhesive and can either be glued directly onto packages or inserted into the label holder on a sterile container. The labels contain a process indicator Type 1 according to EN ISO 11140-1 for steam sterilization processes.

With immediate effect, gke offers a few label models with process indicator for steam sterilization processes, as well as stronger adhesive power. These new, more adhesive labels are specially designed for use on nonwoven packaging material.

The new labels with increased adhesion are available and described and illustrated in the gke catalogue "Chemical Indicators" which can be found under “Downloads” or directly through this link.
