QD-Loop™ Labor-Saving Dilution Device (Hygiena)

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 1:100 or 1:1000 dilution formats. This all-in-one system enables quick and convenient dilutions.
