20mm Superior Flip Cap Vial Seals, Purple, Bag of 1000

Complies with new USP regulations effective December 1 2013. Manufactured in the USA - for use on serum vials with 20mm rim to rim outer top diameter and 13mm hole opening (20mm crimp finish vial). These are far superior in construction compared to regular flip caps. The aluminum seal is constructed with the hole already puched through the aluminum. This greatly reduces the risk that the aluminum tears when removal of the cap. The aluminum stays velvet-smooth after removal of the plastic lid from the aluminum seal underneath. Several colors are available.
