Pereg GmbH
Pereg GmbH offers a special range of indicators and test methods for washer-disinfectors, ultrasonic cleaners, and manual cleaning procedures.
In 1997 we asked ourselves: How can one neglect the most important step when reprocessing surgical instruments? If it’s not clean, it can’t be sterile was a common phrase but there was not much standardisation, quality assurance, or enough science behind cleaning processes.
Now PEREG GmbH is the leading company for cleaning monitoring when reprocessing surgical instruments. This was achieved by believing in the importance of cleaning and knowing the science behind it. In cleaning we do not use standardised parameters as in sterilisation, therefore monitoring a cleaning process needs to be achieved in a different way: Tests for cleaning efficacy must be adapted to the practical situation.
Important Tests
A test soil correlating to blood is one important step but blood behaves differently in various cases such as being cleaned from an ordinary steel surface compared to cleaning the inside of an instrument. Also blood residues after an inefficient cleaning process do not have much in common anymore with fresh blood. We took these important factors into consideration and developed a special range of indicators and test methods for washer-disinfectors, ultrasonic cleaners and manual cleaning procedures:
- The TOSI® Indicator product line combines a standardised test soil correlating to blood with challenge devices simulating a range of surgical instruments.
- The unique SonoCheck verifies efficacy where ultrasonic energy and cavitation is part of the cleaning process.
- The HemoCheck product line is especially designed to detect traces of blood residue after a cleaning process which is a clear sign for inefficient cleaning and a hygiene risk.
- The Pyromol-Test detects protein residues in applications where blood is not the main contaminant.
- The HydroCheck detects residual water in endoscope channel.

TOSI
Routine monitoring and validation of cleaning efficacy according to EN ISO 15883
TOSI test objects are simulated transparent surgical instruments. The contamination is correlating to the practical situation. If a cleaning process cannot clean the TOSI it is not efficient enough to clean blood contaminated instruments! The TOSI will not only give a yes/no answer for blood cleaning efficacy but will also give feedback regarding the cause of a problem. Note: Contaminated instruments are a hygiene risk and need to be rejected. Instruments need to be free of any residue!

Routine monitoring and validation of cleaning efficacy.
ENDOSCOPE WASHERS NEED TO BE REGULARLY MONITORED
The FlexiCheck-system is a unique product for monitoring the cleaning efficiency of the Flexible Endoscope washer. Flexible Endoscopes are often contaminated with mucus however blood is also a possible contaminant. FlexiCheck will monitor the efficiency of the washer and the detergent. TOSI-FlexiCheck combines 2 different test soils on one test strip: One is the standardised blood test soil and the second is a polysaccharide mixture. For reprocessing Flexible Endoscopes washers with channel irrigation systems are recommended. FlexiCheck is connected to this system and will simulate a single channel at one time.
- + A prepared test for monitoring the cleaning efficiency of Flexible Endoscope-washer

HemoCheck-S
Test Kit for detection of blood-protein residue on surgical instruments. Test method according to EN ISO 15883. For routine monitoring and validation of cleaning efficacy.
HemoCheck-S is based on an enzymatic reaction also used in forensic science. Blood contains large quantity of peroxidases and can be detected in very small quantity. Detects insoluble blood-protein residue. Different than standard protein testing HemoCheck-S gives a 100% clear answer by blood being the best marker for a hygiene risk! A colour change to blue-green on the swab indicates blood-protein residue on the tested area. NOTE: Contaminated instruments are a hygiene risk and need to be rejected. Instruments need to be free of any residue.
- + Pre-prepared and user friendly
- + Enzymatic reaction will detect insoluble residue
- + Instant colour change to blue-green indicating blood-protein residue down to 0.1 µg
- + Detects blood residue on surfaces and instruments

HydroCheck-E
Test for residual water in Flexible Endoscopes
HydroCheck-E can detect a very small amount of residual water inside an endoscope channel to avoid recontamination during storage. A swab is used to sample any residual water from the endoscope channel and is then tested with the HydroCheck-E. A purple spot on the swab indicates residual water in the tested channel. Large amount of residual water will turn the swab completely purple. NOTE: Residual water in endoscopes is a hygiene risk to patients. Moisture allows microorganisms to survive and multiply. Endoscopes need to be completely dry before storage.
- + Verify the dryness of Flexible Endoscope channels
- + User friendly, pre-prepared test
- + Purple colour change indicates residual water in the tested channel
- + Detection limit of 0.05 µl residual water
- + Immediate result, no incubation required

SonoCheck
Monitoring the energy of ultrasonic bath for cleaning of surgical instruments Routine monitoring and validation according to AS/NZS 4187.
The process of ultrasonic cleaning relies upon the occurrence of cavitation. This effect will trigger a chemical reaction in the SonoCheck changing its colour. SonoCheck is used to monitor the ultrasonic energy level during the cleaning of surgical instruments. SonoCheck is also used to measure the performance of the individual transducers during the functional test. When the ultrasonic cleaner is supplying sufficient energy, SonoCheck will show a positive result within the recommended cycle time. Effects such as insufficient energy, overloading, water level and de-gassing will increase the time needed for the colour change. In the case of a major problem SonoCheck will not change at all.
- + Detects sufficient energy for cavitation
- + A pre-prepared test showing immediate result
- + Colour change from green to yellow indicating a positive result
- + Easy evaluation
