Multi-component ampules for use with re-useable and disposable jet injectors are described which have primary and secondary packaging components. The primary packaging component includes an inner glass cylinder, an elastomeric diaphragm, and an elastomeric plunger. The secondary packaging components include a plastic outer shell and a plastic adapter. The primary packaging components allow medications and injectable suspensions to be stored for prolonged periods while the secondary packaging components provide structural integrity and adaptability for the ampule. Optionally, thermoplastics having long term storage capability may also be used for the primary packaging components. Exemplary methods for using the jet syringe assembly and of making the same are also disclosed.
