BD Twinpak Dual Cannulas

The BD Twinpak is a dual cannula system built for pharmacy and clinical medication preparation, combining two functions in a single sterile device. Each Twinpak pairs a 20 gauge steel cannula with a 17 gauge plastic cannula, giving compounding and reconstitution workflows a reliable tool for both drawing and venting in one step. This collection carries the BD Twinpak Dual Cannulas (reference 303390) in sterile packaging ready for use in the pharmacy, IV admixture room, or point-of-care preparation.

The design addresses a common frustration in vial-to-vial transfer and reconstitution: pressure buildup and the need to switch devices mid-task. The steel cannula pierces the vial stopper, while the paired plastic vented cannula equalizes pressure to make aspiration smoother and reduce coring and aerosolization of the drug. For technicians reconstituting powdered medications or transferring solutions between containers, that combination speeds the process and helps keep the transfer cleaner.

Buyers most often ask about gauge, sterility, and compatibility. The 20 gauge steel component provides a firm, precise puncture, and the 17 gauge plastic component supports adequate flow and venting. Each unit is supplied sterile for single use, so open only what you need per preparation to maintain aseptic technique. Reference number 303390 makes reordering straightforward for facilities that standardize on the BD Twinpak for their formulary.

Facilities purchasing for a busy pharmacy should confirm case and box quantities to match usage volume, since these are single-use items consumed steadily during high-throughput compounding shifts.
