Most of the guests visited the world’s largest exhibition Medica in Düsseldorf afterwards where gke was presented with a large booth in hall 12.

Two SCBI versions for hydrogen peroxide

Two SCBI versions for hydrogen peroxide

gke now offers two different versions of Mini-Bio-Plus self-contained biological indicators (SCBI) for hydrogen peroxide sterilization processes. They are supplied with the identical spore G. stearothermophilus with a population of 106 and only differ in the carrier (glass fiber or polyethylene/tyvec).

Experience has demonstrated that SCBIs with a tyvec carrier have a significant higher resistance than SCBIs with glass fiber carrier. It becomes apparent that the identical spores with the same population require longer kill time in the same process if different instrument materials are sterilized. This fact has to be considered during validation and routine monitoring.

gke seminar in Olten, Switzerland

gke-Seminar in Olten, Switzerland

In collaboration with Salzmann Medico, St. Gallen, a seminar on reprocessing of medical devices was carried out in the congress hotel “Arte” in Olten. More than 60 attendants from hospitals, surgeries, industry, medical engineering and regulatory authorities took a daylong the chance to get information about process engineering and the possibility of process monitoring during reprocessing.

Salzmann Medico is working closely with gke in Switzerland ( and organized the seminar, issued the invitation and realized practical conduction of the seminar. The gke seminar was held as a full-time training course, where even the breaks could have been used and actually were used for extensive discussions and exchange of experiences.

Best practise to select a cleaning indicator

Best practise to select a cleaning indicator

Automated cleaning processes must be optimized to clean the contaminated goods. Of course the process is different, if e.g. surgical, urological or dental instruments shall be cleaned. Since instruments and their contaminations are quite different, there is a variety of different washer-disinfectors, cleaning programs, detergents etc. Cleaning processes are monitored with artificial test soils, so-called cleaning indicators. But how can a cleaning indicator be selected so that it is suitable to monitor the used process?

The correct practice to select a cleaning indicator is described in the new gke Technical information TI 730-126. This technical information and many other documents about questions concerning reprocessing are available under downloads.

New gke documentation labels

New gke documentation labels

Perforated labels on roll (35 x 78 mm) are often used for documentation in hospitals. gke labels are double self-adhesive and can be adhered directly onto the package and they can be used after sterilization for documentation later on.

The gke documentation labels contain a class 1 indicator according to EN ISO 11140-1 for steam sterilization. Each label needs to show the process to be used in (e.g. STEAM), corresponding standard (e.g. ISO 11140-1) and colour change (e.g. blue to brown). Labels that do not contain this information do not comply with the standard.

gke offers new documentation labels with article number 211-349. The size of the label is 35 x 78 mm and they are now  available on roll with 3” core, double self-adhesive, corner split and perforation between each label (see image). The writing is on the right side so that the whole label height can be used for printing.

The label with article number 211-346 has the same dimensions and is still available (writing on top of the label).

Both versions are in stock. A description with image and order information can be found in the gke product catalogue „Chemical Indicators“ on page 11. The catalogue is available as pdf-file in “Downloads”.

New gke buildings

New gke buildings

For more than 25 years gke has been growing. A large number of products and services have been developed, the distribution network has been extended worldwide and covers more than 70 countries.

gke products are developed and produced in Waldems, Germany and exported worldwide. In the meantime the existing buildings and production facilities are getting too small.

Therefore, three more buildings including production, laboratory, storage and office facilities will be added. Since the start of construction in spring 2014 the progress of construction work is visible and can be seen on our webcam. The picture is updated every day.

After completion new production processes will be installed to develop chemical and biological indicators as well as process challenge devices (PCD).
