Dual Tone Flip top seals for use with all 20mm tubular serum or molded vials from Brands like Wheaton, Kimble, and RLS in combination with grey or red butyl rubber stoppers, 2 or 3 pronged lyophilization stoppers (complete seal and freeze dry pharmaceutical application), and humidity, acid, temperature and chemically resistant clear gel silica stoppers. Flip Top Seals, also known as Flip off and Flip cap seals, are a vital part of the serum vial system, ensuring closure integrity. Features smooth plastic cap edge; plastic disc portion of the seal flips off easily with one hand exposing the aluminum seal with center hole, while leaving no jagged metal edges. Flip cap seal provides the added benefit of a highly visible surface area for easy marking & labeling, as well as product distinction. Manufactured with an integrated security tamper resistant feature that protects targeted area. Contents can be accessed by syringe with attached needle. The advantage of our seals vs. regular flip top seals is that you still have a color coded base aluminum seal after the flip top is removed, as opposed to just plain silver aluminum as is the case with all other flip top seals.
