Superior Flip Cap Vial Seals
SUPERIOR FLIP CAP VIAL SEALS
USA manufactured 20mm superior flip cap seals for serum vials. The unique character of Superior 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 Superior Flip Cap Vial Seals comply with USP regulations for ferrules used in pharmaceutical primary vial packaging.
