RESI-TEST™ Pen

Browne Pen is an alternative application format of the RESI-TEST™ Protein Detection Kit, developed for rapid and direct detection of protein residues in medical device environments. The test is based on the same direct color reaction as the standard version and is used for immediate pass/fail assessment following cleaning.

Upon contact with protein, the color changes to blue, indicating the presence of residual contamination. The analysis is performed immediately after sampling and requires neither incubation nor instrumental reading. The pen format allows for easy and controlled swabbing of specific surfaces.
