BD | Difco Inoculating Loops
BD provides sterile, disposable inoculating loops and needles that do not require flaming. Made from a unique plastic resin, they offer flexible control, and resist cutting the agar surface yet feature sufficient firmness to pick stubborn colonies. They are also color coded.
- State-of-the-art plastic molding technology provides volume delivery consistency. It helps form a correctly sized droplet and completely transfer the volume without leaving behind any liquid beads.
- BD offers the latest plastic injection molding technology to ensure product consistency and minimize lot-to-lot and intralot variations in loop thickness and internal diameter.
- Our loops and needles do not contain lubricants, oils or electrostatic charges, enabling complete liquid transfer and consistent wetting of the plastic, which allows the correct surface tension on the inside walls of the loop.
- BD supplies an Evans blue dye certificate of calibration with every box of loops, confirming their accuracy and consistency.
