Clear Tubular Injection Vials

Injectable drugs demand the most chemically inert glass, because the container is in direct contact with a product that goes straight into the bloodstream. Type I borosilicate — high in silica and boron oxide, with low alkali — gives the highest hydrolytic resistance, releasing minimal ions into the drug, which is why it is the standard for parenteral vials.

Tubular vials are converted from precision borosilicate tubing, giving the thin, uniform, dimensionally exact body that high-speed aseptic filling lines and automatic stoppering need.

Liquid injectables, lyophilised (freeze-dried) drugs, vaccines, biologics and antibodies, diagnostic reagents, clinical-trial fills, hospital and compounding pharmacy, and veterinary injectables. Ready-to-use nest-and-tub formats serve fill-finish lines directly.

A clear Type I borosilicate tubular vial with a 13 mm or 20 mm crimp finish, sealed by a rubber injection stopper and an aluminum crimp cap with a flip-off button. The blowback and finish geometry are designed so the stopper seats and seals reliably. Amber and ready-to-fill (washed, depyrogenated, sterilized) grades are available.

Injection vials are part of a validated container-closure system: the glass, stopper and crimp seal are tested together for integrity, and filling is aseptic. For lyophilised products the stopper is half-seated for freeze-drying then fully seated and crimped. Container-closure integrity, particulates and glass delamination risk are all controlled for parenteral use.

Made by converting Type I borosilicate tubing on rotary forming machines that shape the base and crimp finish to tight tolerances, then annealed. Pharmaceutical vials are produced under controlled conditions and inspected for dimensions, cosmetic defects and, increasingly, delamination propensity. Ready-to-use vials are washed, depyrogenated and sterilized.
