Orion Clean Card Pro 25tk

Rapid test for verifying cleaning results and the presence of protein residues on cleaned surfaces. The package contains 25 test strips. The reagent pad on the test strip reacts with protein, causing a color change. The result is obtained quickly, allowing the cleaning process to be repeated before the surface is used.

Usage:
Moisten the sample area to be tested (approx. 10x10 cm) by spraying a few times with clean water from a spray bottle. Wipe the test area with the test strip first horizontally from edge to edge, then vertically from edge to edge. Read the result after 30 seconds and evaluate it according to the table included in the package. The result remains unchanged for approximately 30 minutes.
If the perforated area of the strip turns yellow, the surface is clean. If the color changes to green or blue, the surface being tested is not clean. The darker the color becomes, the more protein is present in the sample area.
There is no limit value for protein contamination; instead, the user assesses the critical cleanliness level of the surface.
