Crimp Top Vials, 12 x 32 mm

Crimp top vials, 12 x 32 mm, are available in two different openings. The original opening size of 4.6 mm I.D. (standard opening) is available, as well as the newer design of 6.0 mm I.D. (large opening).
The benefit of the larger opening is that it provides an increased target area for the injection needle to enter the vial.
