13mm SNAP ON style vial stoppers, manufactured in the USA using gray chlorobutyl rubber, for vials with a 13mm crimp finish and blowback feature.
13mm SNAP ON style vial stoppers are normally used on smaller 2ml vials and 3ml serum vials.
13mm snap on vial stoppers offer the best sealing for serum vials manufactured with a blow-back glass finish. A "blow-back" neck finish is a small ridge on the interior of the vial neck. These snap-on stoppers lock into the blow-back ridge, allowing for a more secure seal and helps prevent the stopper from popping back out.
