Labor-Saving Dilution Device
QD-Loop device is an all-in-one, sterile, rapid system for accurate and convenient volumetric dilutions. An accurate loop or dipper comes attached to a reservoir where patented Snap-Valve™ technology holds 1mL of Butterfields or Maximum Recovery Diluent (MRD) buffer. Simply break the Snap-Valve after a sample is collected, and immediately a dilution is ready that can be poured onto dry media film or streaked onto an agar plate.
QD-Loop comes in 1:10, 1:100 or 1:1000 dilution formats. This all-in-one system enables quick and convenient dilutions.

Reliable and accurate changeover cleaning verification.
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.
