Injection vial
Injection bottles (also known as vials ) are small bottles that are used in medicine and in chemical laboratories . They can be provided as a single-dose or multiple-dose container. Powdered medicinal substances , solutions or suspensions can be filled in them. In general, the vials have a capacity between 1 and 200 ml . They are closed with a rubber stopper (injection stopper) or a PTFE septum ( puncture membrane ). This is provided with a flanged cap made of aluminum fixed on the bottle neck. This rubber stopper has the smallest thickness in the middle; this point is for sucking the injection fluid to the injection needle pierced.
Vials are also filled with dry substance, as some drugs are not stable enough. The solution is made by adding sterile water or water with an isotonic additive. This is usually included in the pack in the form of a solvent ampoule. The stopper is pierced with an injection needle and the water is added shortly before application.
In biotechnology, vials are usually plastic tubes with a capacity of 1–10 ml that are used, among other things, for inoculum production in upstream processing and for the cryopreservation of animal cell cultures . Vials are the standard system for creating cell banks.
