Pharmaceutical injection vial

Pharmaceutical injection vial · Type I borosilicate tubing glass, ISO 8362-1 size (2R–100R) and neck finish, clear or amber, stopper and crimp cap, bulk or ready-to-use, delamination risk

A pharmaceutical vial is the glass or polymer container, closed with an elastomer stopper and a crimped cap, that holds an injectable drug from filling to use. Ask three things first: which glass type and treatment suit the formulation, which ISO size and neck finish match your filling line and closures, and whether you need bulk or washed, sterilised ready-to-use vials.

Injection vials for parenteral drugs, vaccines and biologics made from glass tubing (ISO 8362-1 formats). Rubber stoppers (see pharmaceutical vial rubber stopper), vial inspection machines, laboratory HPLC/GC sample vials, ampoules and cartridges are outside this page.

01

Choose the glass, colour and inner surface for the drug

SGD Pharma makes its tubular vials from Type I neutral borosilicate glass compliant with USP, EP and JP requirements, in clear and amber, with options including an external coating for fill-finish performance and ammonium sulphate treatment, in ISO 15378- and ISO 9001-certified facilities. [3]

SCHOTT Pharma describes glass delamination as glass-like flakes in the drug solution caused by inhomogeneity in the near-bottom region, induced by hot forming and influenced by terminal sterilisation, storage temperature, special treatments and buffer type; it notes aluminium, a component of Type I glass, can leach into the drug, which matters for parenteral nutrition containing amino acids. For lyophilised drugs it cites fogging and freezing stress, addressed by a hydrophobic inner surface. [1]

SCHOTT Pharma states its EVERIC amber vials, made from FIOLAX amber tubing, comply with the light-transmission requirements of USP, Ph. Eur. and JP, with 100% inline inspection and a certificate of compliance for light transmission. [2]

Give the supplier the drug type and pH, liquid or lyophilised fill, light sensitivity, sterilisation method, storage temperature, ISO size and neck finish, colour, coatings or treatments, bulk or ready-to-use format, stopper and cap system, quantity, and the pharmacopoeias and certificates required.

02

Choose the ISO size, neck finish and supply format

SGD Pharma's ISO 8362 range runs 2R to 100R, with a 13 mm neck finish for 2R and 4R and a 20 mm neck finish for 6R, 8R, 10R, 15R, 20R, 25R, 30R, 50R and 100R, plus screw, EBB and ABB necks and non-standard formats; its vials are inspected for dimensions, cosmetics and breaking load. [3] SCHOTT Pharma notes vials store volumes from less than 2 ml up to 100 ml. [1]

SCHOTT Pharma describes the injectable vial as container, stopper and cap: the elastomer stopper, with optional coatings, is a barrier to contamination and evaporation, and the cap holds the stopper to keep container closure integrity; SCHOTT writes: "Typically made of aluminum, vial caps are usually attached to vials for injectables by crimping." [1]

Taian Youlyy lists ISO 8362-1 Type I neutral borosilicate tubular vials in clear and amber, and washed sterile ready-to-use vials washed with pharmacopoeial water for injection in a Class A clean workshop, supplied pyrogen-free in an industry-standard nest-tub and re-sterilised with ethylene oxide, citing ISO 8362, ISO 11040 and ISO 15378.
