Weber Scientific’s Aller-Snap is a quick and easy way to accurately monitor the cleanliness of surfaces to help ensure product quality. It detects protein residues left on a surface after cleaning. Simply swab a surface, release the reagent and if protein residue is present the reagent will turn purple. The color change provides a semi-quantitative measure of the surface cleanliness. The more contamination present, the quicker the color change to purple and the darker the color. Aller-Snap quickly validates the hygiene of a surface, allowing immediate corrective action to be taken if necessary. It requires incubation, 55 C for 15 minutes or 37 C for 30 minutes.
