Hygiena QD Loop - 10µl Sample Pickup (1-100 dilution) (250) QD100

The QD-Loop is an all-in-one, sterile dilution device for rapid, accurate volumetric dilutions used to collect and immediately prepare plated dilutions. An accurate 10 µL loop/dipper is attached to a reservoir containing 1 mL of Butterfields or Maximum Recovery Diluent (MRD) held by a Snap-Valve; after sample collection the Snap-Valve is broken and the ready dilution can be poured onto dry media film or streaked onto an agar plate. Typical use cases include point-of-collection sample pickup and on-site preparation of 1:100 dilutions for microbiological plating and environmental monitoring.

Key Features:

• Sample pickup volume: 10 µL
• Dilution format: 1:100
• Reservoir buffer volume: 1 mL (Butterfields or Maximum Recovery Diluent/MRD) retained by Snap-Valve technology
• Sterile, single-use all-in-one loop plus reservoir
• Quantity: 250 items per box (part code QD100)
• Storage recommendation: refrigerate; store between 2°C and 8°C

Advantages:

• Provides immediate ready-to-plate dilutions at the point of collection, eliminating separate buffer preparation
• Integrated Snap-Valve reservoir and loop reduces the need for pipettes and additional lab equipment
• Sterile, single-use design reduces contamination risk and simplifies workflow
• Reduces labor and laboratory equipment expenses by enabling quick, convenient volumetric dilutions
