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.

If you have further questions, don’t hesitate to contact our application lab.

Further information can be found on the product data sheet under "Downloads" or directly via this link. Request a sample!

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

510K Registration for Steam-SCBIs

gke got US FDA-registration for Steam-SCBIs

gke has received the 510(k) registration of the US american Food and Drug Administration (FDA) for their self-contained biological indicators (SCBI) for steam sterilization processes which will now be distributed in the US.

The self-contained biological indicators (SCBI) are used to monitor steam sterilization processes and are already sold into more than 50 countries by gke.

gke products with German/English packaging

gke products with German/English packaging

gke manufactures its products in Germany and distributes the goods around the globe. In different countries the products and accompanying documents are packaged in national languages. To the article numbers a 3-digit letter code is added. The additional letter code refers to the language, e.g. ENS (for English Standard). 

To reduce the warehouse stock of both standard versions (German and English) those products will be combined in an English-German version. The 3-digit letter code will change from “ENS” to “EDS”.

The content of the packages will not change. The outside label and directions for use will be added in both languages (German and English).

This change allows gke to keep the prices for 2016/17 on the same level without any increase in price.   

Seminar activities in South America

Lectures and seminars in South America

The annual SOBECC conference with more than 2.000 participants took place from August, 31st until September, 2nd, 2016 in Sao Paulo. Dr. Kaiser CEO of gke gave a lecture about the importance of water quality which is necessary for the water supply in manual or automatic washer disinfector cleaning processes and steam sterilization processes.

gke and P&E have carried out a full-day seminar with about 70 participants in Santiago de Chile discussing the aspects of steam and H2O2 sterilization processes.

Together with Techndomus, the gke distributor in Mexico, gke has carried out an educational seminar about cleaning and sterilization reprocessing in hospitals with 250 participants in Mexico-City.

New gke labelling device

Labelling device – New model NL

The gke labelling device is now easier to handle. Design, dimensions and handling remain unchanged. The new version is smooth-running in comparison to the old version. Thereby a large number of labels can be generated in a short time with less effort.

Using the gke labelling device 3-line labels can be easily labelled. The first printing line contains three alphanumeric digits, e.g. to print the initials for the person responsible, followed by nine numeric digits to print sterilizer and batch number. The second and third printing lines contain 12 numeric digits for production and expiry date.

The previous version with art.-no. 240-850 (product code: D-G-N) is not available any longer and will be replaced by the new version with art.-no. 240-820 (product code: D-G-NL). For orders, that contain the old article number, the customers will be informed and the new version will be delivered.

Wash-off characteristics of gke cleaning process indicators

Wash-off characteristics of gke cleaning process indicators

The gke cleaning process indicators are used to monitor mechanical cleaning processes. gke offers different cleaning process indicators for washer disinfectors (WD) which represent different challenge levels as proof of the cleaning efficacy. Therefore, it is recommended to test all indicators at the same time to select the appropriate indicator for process monitoring.

gke has carried out two test runs in a WD using different detergents. The process has been monitored with a camera through the glass door of the WD. The gke cleaning process indicators are each placed in a holder. Four gke indicators are placed horizontally and sprayed directly. Four indicators are placed towards the front and are sprayed indirectly with the reflected water of the glass door. Both videos show the different wash-off characteristics of gke cleaning indicators over time.

Have a look at the videos that can be found under “Products/Washer Disinfectors” or directly through this link. In a pdf-file below the videos the single steps during the process are explained. With mobile devices the videos can easily be watched by scanning the qr-code below.

Test the gke cleaning process indicators in your process and determine the test soil that is suitable to monitor your process.

New standard draft for biological indicators

New standard draft for biological indicators

During the last ISO meeting gke has offered a standard draft where biological indicators are characterized to check sterilization processes with hydrogen peroxide.

In this draft a test method is presented to determine the resistance of biological indicators for hydrogen peroxide sterilization processes. It will allow to compare biological indicators of different manufacturers for the first time. Using this test method the innactivation kinetics can be determined. This is a very important step to validate and monitor hydrogen peroxide sterilization and disinfection processes.

The test results will be soon published in the “Central Service” magazine.

New gke test system

New gke test system

Type tests described in sterilizer standards EN 285 or EN 13060 are used to test the standard conformity of sterilizers and they are used like the Bowie-Dick Test to check the sterilizer after start-up working correctly.

Sometimes paper packages and helix systems are used for routine monitoring to check the sterility of the load. This procedure is quite often batch monitoring. These tests have no relation to the load. Therefore, it cannot automatically be concluded that loads of complex MIS instruments can be sterilized successfully.

Since the load configuration in hospitals is changing according to the different type of operations carried out routine monitoring to check sterility has to be adapted to the load and cannot assure if the sterilizers are working according to the sterilizer standard requirements only.

This adaption can be achieved in two ways:

  1. Process Monitoring System (PMS): The sterility of the load is assured if the sterilization process has been validated with a worst-case load. The continuous monitoring of the load shall be carried out with a test system which monitors the maximum performance of the sterilizer. Modern sterilizers provide much better performance than the required type tested mentioned above. For this purpose gke offers a variety of different PCDs (process challenge devices) with increasing sensitivities to monitor the process at highest level. These test devices are called process monitoring systems (PMS).

  2. Batch Monitoring System (BMS): If the characteristics of the load to be sterilized are known, a PCD can be designed and validated to be more difficult to sterilize than the defined load using the method according to DIN 58921 (medical device simulator). gke has already tested several typical loads with the method according to DIN 58921 and offers special PCDs for tattoo, dental and ophthalmic loads. For these test systems separate data sheets with detailed information are available.

gke has extended its product range with different test systems having even higher requirements than the hollow load test described in EN 867-5 and which shall be used as a batch monitoring system with every sterilization cycle selected according to one of the procedures described above.

The test system gke VHDH-PMS (very high demand hollow process monitoring system) with Compact-PCD, brown is now available and represents extreme complex instrument loads. More information about this test system and other gke PMS and BMS can be found using the links. The product data sheet is available for download following this link or under Downloads/Product Catalogues and Data sheets.

New dental brochure

New dental brochure

The reprocessing of dental instruments can differ from other sterilization processes in health facilities.

gke has created a comprehensive dental brochure to explain the application and necessary products for cleaning and sterilization monitoring in dental facilities.

The new brochure is available for download following this link or under Downloads/Product Catalogues.

Self-contained biological indicators (SCBI)

Self-contained biological indicators (SCBI) for sterilization monitoring

Biological indicator strips G. Stearothermophilus and/or B. Atrophaeus are still used. However, those products are old-fashioned and require a microbiological laboratory with a long delay time until the result is available. Modern self-contained biological indicators (SCBI) can be incubated directly after the sterilization process is finished having the results available after 5-24 h. By using gke Steri-Record Instant-SCBIs the sterilized goods can be released very quickly at the end of a steam sterilization process.

This is a very time-saving and cost-effective method compared to the use of traditional spore strips.

Please contact us or your local gke-dealer. The gke application laboratory may support you in technical questions. More information is available by following this link.

Self-contained biological indicator (SCBI)

New labels to be used on containers

New labels to be used on containers

Containers made of stainless steel, aluminium or plastic cannot be adhered with conventional labels since glue residues will remain on the surface. Therefore, many containers have openings where labels can slide-in. The labels need to have special dimensions and are mostly not big enough to add all data. Furthermore the label is placed on a certain position and cannot be scanned without shifting the container.

gke has developed a single self-adhesive label which can be adhered on the container without leaving any residues. Therefore, extensive cleaning with organic solvents is unnecessary. The use of under foil or film for easy removal of the label is also not anymore required.

The labels are available on roll with 3” core, other core diameter and dimensions on request. The labels can be ordered as endless labels for printers with cutting device or single perforated labels with 6 and 8 cm width.

Please request a sample roll for testing!

New gke buildings

Opening of new gke buildings

The 3 new buildings with an area of 10.000 sm have been completed.

gke will move into some parts of the new buildings in the next couple of months. The new buildings come with high speed glassfiber internet connection, easy accessibility with elevators, air-conditioned conference- and server rooms, 6 truck ramps and a covered parking area for 125 cars.

On the roof of two buildings a photovoltaic plant with 200 kW maximal power point (MPP) has been installed which produces a large part of the required power. Rain water is collected in a cistern and used for toilet flushing. Efficient energy saving LED lights are used, the buildings are isolated and only need low heat capacity in the winter and air-conditioning is only necessary in the conference and server rooms.

Standard ISO 11140-6 will replace EN 867-5

Standard ISO 11140-6 will replace EN 867-5

The ISO/TC 198/WG6 working group has been working for more than 3 years to replace the old EN 867-5 by a new ISO Standard. Continuous tests have been carried out to replace the old Hollow Load test procedure in the EN standard which did not give reproducible results.

The new EN ISO 11140-6 specifies performance requirements and test methods for chemical indicators and process challenge devices intended for use in small steam sterilizers, which are intended to sterilize solid, hollow and porous medical devices.

The ISO committee stopped this work item after 3 years because of exceeded deadlines. During the last meeting of the working group in Denver/USA, ISO has decided to continue this work in order to finalize a new standard ISO 11140-6.

This modification is important because currently a lot of different alternative Hollow Load Tests are on the market and all claim to be equivalent to the original Teflon Hollow Load Test. However, they differ in sensitivity.

Cleaning indicator for bedpan washers

Cleaning indicator for bedpan washers

The cleaning efficacy in bedpan washers has to be checked regularly. Until now bedpans have been manually contaminated with a test soil, e.g. mustard, saw dust, wheat flour, ketchup or other. After cleaning the positions can be determined where the spray jet is redirected and the cleaning is poor.

By using the new gke cleaning indicators level 0 this test is quick and easy. The self-adhesive indicators will be be adhered directly on the bedpans or urine bottles. At the end of the process they can be documented with the same adhesive.

The data sheet with detailed information is available through this link or in „Products/Cleaning monitoring/Bedpan washers".

International Dental Show in Cologne

International Dental Show in Cologne

Dentists, manufacturers of dental equipment, dealers and other participants visited the gke-booth during the International Dental Show (IDS) which took place from March, 10th – 14th in Cologne, Germany.

The IDS is the largest dental show worldwide. gke took the chance to present its products for process monitoring and documentation especially for dental instruments.

The technical equipment of dental practices becomes more comprehensive. Practices and dental units worldwide invest in high quality washer disinfectors and sterilizers. The monitoring can be carried out with special gke test systems for dental instruments.

gke participates in large exhibitions and gke will also be present with a booth at Medica in Düsseldorf in November 2015.

Updated EN ISO 11140-1

New Version of Standard EN ISO 11140-1

Chemical indicators to monitor sterilization processes are described in the standard EN ISO 11140-1 and are divided into six different indicator types (former classes). The number does not allow any conclusion about the quality, e.g. an indicator type "6" according to EN ISO 11140-1 is not "better" than an indicator type "2", but specifies different characteristics by application. The type 2 indicator systems are intended for use in specific tests, where a PCD (process challenge device) is used.

The standard EN ISO 11140-1 has been updated. The process challenge device is now defined as PCD and the corresponding indicator strip is called indicator. The combination of PCD and corresponding indicator is defined as indicator system type 2. From now on the everyday language and the terms of the standard are identical and easier to understand.

The details are described in our technical information TI 730-044, available through this link or in „Downloads“.

International Dental Show

International Dental Show in Cologne

Taking place every two years, IDS in Cologne is the top event for the international dental sector with more than 2000 exhibitors and over 100.000 national and international visitors.

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”.
