Demineralised process water: Hygiene and Disinfection
Hygiene and Disinfection
With our HyMo-Box “Sterilisation Check”, you can microbiologically validate and routinely check your steam sterilisation devices in accordance with the standards DIN EN ISO 17665 and the European Pharmacopoeia*.
The bio-indicators contained in the HyMo-Box enable you to check the proper functioning and sterilisation performance of your steam sterilisation devices, thus ensuring the hygiene safety of the tools you use.
Horizontal table and floor-standing autoclaves, pass-through autoclaves and vertical floor-standing autoclaves are just some of the models in which you can use the bioindicators.
In addition, you can use the supplied RODAC plates to check the environment, such as work surfaces, etc., for their germ load using the contact plate method.
In this way, other areas such as shelves or your employees’ hands can also be monitored. This allows you to identify weak points and adapt your cleaning and disinfection plans. This is how you ensure that the environment is permanently low in germs.
Scope of delivery HyMo-Box Sterilisation Check:
- 20 RODAC plates for examining surfaces
- 2 bio-indicators with spores of the test germ Geobacillus stearothermophilus
- 1 transport control of the bio-indicator
- 1 waterproof pen
- 1 bottle of hand disinfectant
- 1 cooling element
Bioindicators for self-monitoring the effectiveness of the sterilisation/autoclave process
There are several standards that govern the testing and associated validation of autoclaves in healthcare facilities:
- EN ISO 17665 – 1:2006-11
- DIN EN 554
- DIN 58946-7:2014 – 01
- DIN EN 285: 2016 – 05
- EN ISO 15883
The bioindicators are added to the autoclave or the autoclaving process. This is to provide evidence that the test germ “Geobacillus stearothermophilus” has been successfully killed. This is how a biological check of the sterilisation process is carried out using the HyMo-Box.
The bioindicators are removed after the sterilisation process and sent to the accredited Hohenstein laboratory, where they are analysed. The bioindicators are examined in the laboratory. The sterilisation process was not successful if the test germ “Geobacillus stearothermophilus” grows. If this is the case, further considerations regarding the sterilisation process with the operator in terms of settings (e.g. temperature, programmes, dosage…) and the functioning of the steriliser must be carried out following the evaluation.
Safe sterilisation can be verified by laboratory testing to confirm that the test organism has been successfully killed.
The use of bioindicators for sterilisation is intended to ensure that the devices are biologically safe. The bioindicators and the sterilisation box (HyMo-Box), which is also available as a complete set, can be used in smaller facilities such as outpatient clinics and doctors’ practices, as well as in hospitals and clinics.
