QD-Loop rapid dilution device is an all-in-one sterile system for accurate and convenient volumetric dilutions. An accurate, calibrated loop comes attached to a reservoir where patented Snap-Valve™ technology holds 1.0 mL of Butterfields or Maximum Recovery Diluent (MRD) buffer. Simply break the Snap-Valve after a sample is collected, and immediately a dilution is obtained 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 allows the making of dilutions quicker and more convenient.
