Glossy USA Flip Cap Vial Seals
GLOSSY USA FLIP CAP VIAL SEALS
USA manufactured 20mm glossy flip cap seals for serum vials. The unique character of these Flip Cap Vial Seals is that the center perforated ring of aluminum has already been removed. This eliminates the concern about rough edges of metal being exposed after removing the plastic flip cap. Several colors are available in a beautiful, glossy, non-embossed finish. The Flip Cap Vial Seals comply with USP regulations for ferrules used in pharmaceutical primary vial packaging.
