Hygiena® QD-Loop™ - Sterile Rapid Dilution Device for Microbiological Testing

The Hygiena QD-Loop™ is an all-in-one sterile device that delivers accurate 1:100 or 1:1000 volumetric dilutions in a single step. Designed for food safety laboratories and quality control professionals, this tool integrates a calibrated sampling loop with a pre-filled Butterfields buffer reservoir. The patented Snap-Valve™ technology eliminates the need for separate pipettes, tips, and dilution bottles, reducing labor costs and minimizing calculation errors. Gamma irradiated for sterility assurance, the QD-Loop is compatible with agar plates and dried media film for flexible downstream testing.
