Molded Antibiotic Vials

Where tubular vials are drawn from tubing, molded vials are formed directly from a gob of glass by press-and-blow, giving a thicker, sturdier wall and a heavier, more stable base. That robustness suits antibiotic and lyophilised products that are reconstituted at the bedside — vials that get handled, inverted and pierced under less-than-gentle conditions.

The thicker wall also lends itself to larger volumes; molded vials cover the bigger sizes where tubular vials become impractical, while keeping the Type I or Type II glass that injectables require.

Antibiotic powders, lyophilised injectables, reconstitutable drugs, larger-volume parenterals, veterinary injectables, diagnostic and reagent kits, hospital and compounding pharmacy and vaccine bulk. The robust format suits products that are mixed and drawn at the point of care.

A molded vial in Type I borosilicate (for sensitive products) or Type II treated soda-lime (sulfur-treated for improved surface resistance), with a 20–32 mm antibiotic crimp finish for a rubber stopper and aluminum seal. The thicker wall and heavier base give strength and stability; clear or amber glass as the product requires.

As with all parenteral containers, the glass, stopper and crimp are validated together as a container-closure system. Powder-fill and lyophilised vials are stoppered and crimped to maintain sterility until reconstitution. Type II glass suits products where surface hydrolytic resistance is enough; Type I is used for the most sensitive formulations.

Molded vials are press-and-blow formed from individual gobs of pharmaceutical glass, giving the thicker wall and stable base, then annealed. Produced and inspected to pharmaceutical standards for dimensions, defects and glass type. Ready-to-use grades are washed, depyrogenated and sterilized.
