CLEANING VALIDATION COUPONS
WHAT ARE THEY FOR?
A cleaning validation coupon is used in the laboratory to validate a proposed swabbing method.
Example: if your proposed method for swabbing involves a solvent, say methanol, how do you know if that solvent and the swabbing technique you are going to use will actually recover the residue from the surface?
In order to determine the efficiency of your swabbing method in recovering the residue, a cleaning validation coupon, matching the material of construction and the finish of the subject surface, is spiked with known amount of a solution of the residue of known concentration, dried, and swabbed with your proposed swabbing method and the swab analyzed for the residue. If the recovery of the residue is within acceptable limits, then you can proceed to do the swabbing on the subject surface.
QAQC LAB offers coupons made of several different materials with different finishes, such as 316 stainless steel, 304 stainless steel, aluminum, brass, bronze, a variety of plastics and rubbers, etc. Standard dimensions of the coupons are 50 mm x 50 mm, and 100 mm x 100 mm.
