Procheck E-W is a ready-to-use rapid protein residue detection system for testing any surface after the cleaning process, especially for the food and beverage industry.

This test is intended to provide rapid validation of hygiene levels of a surface and show due diligence in a HACCP program. Although Procheck detects bacteria and mold, it is not intended to be a microbiological monitoring tool.

Procheck E-W turns from yellow to green if protein is present on the sample surface. The more protein collected in the sample, the more distinct the color change.
