Pharmacological Profile & Mechanism of Action
What it is: Box of 100 sterile 18-gauge, 1.5" (38 mm) blunt-fill transfer needles incorporating an integrated 5-micron particulate membrane disc within the needle hub.
How it works: The 45° blunt tip requires 10x less piercing force to traverse vial septa without coring rubber stoppers, while the 5 µm membrane prevents glass ampoule particles or rubber fragments from being drawn into the reconstitution syringe.
Why researchers study it: Recommended under GLP laboratory handling guidelines for diluent reconstitution draws and ampoule fluid transfer.
