Rapid Protein Residue Test

AllerSnap™ is a quick and easy way to verify the cleanliness of surfaces by detecting protein residues left behind after cleaning. By simply swabbing the area and activating the device, you release a reagent that turns color, providing a qualitative and semi-quantitative result of the protein levels on the surface: green means clean and purple means re-clean. The more protein present, the quicker the color change to purple and the darker the color. AllerSnap™ quickly validates surface hygiene, allowing immediate corrective action to be taken when necessary.

A prevention program that works for you.

Studies have shown that incorporating high sensitivity ATP testing with protein residue detection can result in an ultra-efficient surface allergen prevention program. See the research below. With SuperSnap™ and the EnSURE™ monitoring system, you can maximize your allergen prevention program by eliminating cross-contamination, ensuring product integrity, and protecting brand reputation, making sure allergens don’t make it into your product. How does it work? SuperSnap is a highly sensitive all-in-one test that detects extremely low levels of ATP residue, similar to low levels of protein residue. Test results are measured with the EnSURE™ and data is recorded with SureTrend™ software, so you can track, trend, and analyze your test results with charts and graphs. Learn more about SuperSnap.
