For more than 30 years GKE develops, produces and sells indicators for monitoring and documentation of cleaning, disinfection and sterilization processes.
About 50 persons work at the company’s headquarter in Waldems-Esch, Germany, approximately 40 km north of Frankfurt / Main, where the departments for research, development, production and worldwide sales are located.
GKE develops indicator ink for chemical indicators and produces them on a 7 colour printing and rotating die-cutting machine.
GKE produces biological indicators in its own microbiological facilities. The inoculation of indicators with spores is carried out automatically with robot technology.
GKE products are sold in more than 80 countries worldwide in cooperation with specially trained local distribution partners. For more than 15 years GKE operates its own sales company in China, which imports the GKE products manufactured in Germany and distributes them within China via other sub-distributors.
Specialists for process technology, microbiologists and chemists conduct basic research to study cleaning, disinfection and sterilization processes under laboratory conditions. A big number of special test washers and sterilizers are available, several of which have been developed and built in-house, in order to be able to measure cleaning and sterilization indicators independently in a process-controlled and reproducible manner. GKE cooperates with its partner company, SAL GmbH, which is an accredited testing laboratory according to EN ISO 17025.
As results of its research, scientific papers are published regularly, GKE participates in congresses, carries out training courses and is active in international working groups, including standardization.
GKE indicator test systems make process deviations visible that would otherwise remain undetected. GKE has developed artificial test soils (Cleaning Process Indicators - CPI) especially for the monitoring of automated cleaning processes, having wash off properties which can be adapted for nearly any application.
GKE-CPI and all other GKE test systems are used in research, process validation, equipment service and routine monitoring. GKE test systems detect process deviations which might otherwise go unnoticed, which is an important contribution to ensuring the reproducibility of critical cleaning and sterilization processes.
