If protein residue is present, the reagent will turn purple - the more contamination, the quicker the color changes and the darker it becomes. PRO-Clean instantly validates surface hygiene, allowing immediate corrective action to be taken when necessary.

Why test for protein residue? Protein is more difficult to remove from surfaces than glucose or other residues, so it's a good indicator for surface contamination. If you need to verify protein removal quickly, PRO-Clean is reliable and accurate.
