Germlyser® G

Point-of-use hollow fibre membrane filter for manual rinsing of endoscopes

Effective membrane filtration for the protection against waterborne bacteria in manual endoscope reprocessing

  • Safe water hygiene
  • Quick and easy installation
  • CE-marked medical device
  • Reusable product with reprocessing and delivery service
The point-of-use hollow fibre membrane filter Germlyser® G is a CE-marked medical device, which is specially developed for manual final rinse of endoscopes and can be fitted directly to the water outlet of the spray gun. The 0.2 µm hollow fibre membrane removes all waterborne bacteria. The housing of Germlyser® G is made up of plastic including an additive with special bacteriostatic properties. This prevents the growth of bacteria which may reach the filter through splash water or contact (retrograde contamination). The used additive in plastic is tested and approved for food and medical devices. Germlyser® G delivers a constant high flow rate of bacteria-free water over its entire operating time and effectively protects against recontamination from final rinse of endoscopes.

Germlyser® G is a high quality, reusable product which is available to customers at a rental rate. The filter can be used immediately after filter installation. The customer will receive reprocessed filters for exchange before the operating time of the previous filter has elapsed. The quick-release coupling makes the exchange of the filter quick and easy. The used filters are picked up by the logistic partner and returned to Aqua free service centre. Each filter is reprocessed at the service centre according to RKI recommendations. Similar to a subscription service, Aqua free service concept is safe and simple.
When reprocessing endoscopes, there is a risk that the tap water used to remove disinfectant residues might be contaminated with bacteria. For this reason, the final rinse in manual and automatic endoscope reprocessing can lead to recontamination in the already cleaned and disinfected canals of the endoscope. Since 2002, the Robert Koch-Institute (RKI) has recommended the use of water filtration to safely remove disinfectants without the risk of recontamination. The Commission for Hospital Hygiene at RKI has published its recommendations in, “Demands on Hygiene in Reconditioning Flexible Endoscopes”: “For the final rinse, water should be used, which is of the same microbiological quality as drinking water and is free of facultative pathogenic microorganisms. Sterile water filters can be used to provide sufficient volumes of microbiologically pure water.”

1The operating time can be increased up to 8 weeks if sufficient hygienic measures exist and an adequate hygiene plan is carried out. We recommend monitoring by appropriate clinical microbiological testing.

2The Germlyser® G must not be connected to low pressure units.
