Chemdye® SWE high-absorption swabs have been specifically designed for use with cannulated instruments. These swabs must be inserted through the internal channel of the cannula, allowing the collection of contaminants that may persist after the cleaning process. SWE swabs are designed for use with Chemdye® PRO 1 ENDO system, enabling the verification of the cleaning efficacy of cannulated instruments by detecting and quantifying protein residues that may remain after the cleaning process.
KPRO2-E250 / Designed to detect proteins on endoscopes and other reusable instruments with hard to reach internal channels or cannulated instruments.
The first step in properly cleaning surgical instruments is to rinse off all blood, bodily fluids and tissue immediately after use. If cleaning is not carried out adequately, it may render the disinfection stage ineffective, causing patients to be exposed to body fluids and tissue contaminants from prior patients, which can result in the transmission of pathogens and affect large numbers of people.
Chemdye® KPRO2-E69 and KPRO2-E250 Hygiene Systems were designed to check cleanliness of surgical equipment by detecting protein residues after an improper cleaning. The systems have a high absorption swab, allowing the collection of samples from different surfaces with the same efficacy. The systems are compatible with cleaning verification of endoscopes and other reusable instruments with hard to reach internal channels or cannulated instruments.
For this, use the special SW250 endoscope swabs, which may be introduced through the biopsy channel of the endoscope to sample contaminants left after the cleaning process. A visual color change indicates the presence of detectable levels of protein. KPRO2-E69 and KPRO2-E250 have high sensitivity and can detect as little as 1 μg of protein.
The first step in proper cleaning of surgical instruments is to remove blood, body fluids, and tissues immediately after use. If cleaning is not performed
properly, the disinfection/sterilization steps will not be effective, leading to the exposure of patients to contaminants such as body fluids, tissues from other patients, and microorganisms.

Verifies time, temperature, and steam quality simultaneously inside every pack Double-strip format – two-point confirmation within the same package Mid-level monitoring – higher assurance than external or single-variable indicators
Instant visual confirmation of H₂O₂ exposure – seals items and confirms sterilisation in one step Compatible with cloth, paper, and plastic packaging -leaves no residue on removal 50-metre roll – economical for high-volume departments
Type 4 multi-variable – verifies H₂O₂ concentration, temperature, and time simultaneously inside every pack For plasma and vaporized H₂O₂ low-temperature sterilizers – ideal for heat-sensitive items and flexible endoscopes Toxic heavy metal-free · FDA cleared
Type 6 emulator – highest specificity available; reacts only when all exact cycle parameters are precisely met 3-point emulation validates both standard healthcare cycles: 134°C / 3.5 min and 121°C / 15 min Unambiguous blue to black result – monitors time, temperature, and steam quality in a single indicator Precise in-load feedback for strict cycle control – ideal for validation and routine documentation 100% free of toxic heavy metals.
Type 5 integrator – responds to all critical variables; endpoint calibrated to 10⁶ G. stearothermophilus spore kill time Closest chemical surrogate to a biological indicator – provides the highest level of chemical assurance Simple SAFE / UNSAFE result – turns black only when full integration conditions are met.
Instant visual confirmation that a package has been exposed to steam – prevents use of unprocessed items Seals wraps, pouches, and rigid containers – no residue on removal 50-metre roll – practical and economical for high-volume departments.
