The distinct glass vial component in a single dose nasal spray device serves as the primary vessel for the pharmaceutical formulation. Made from borosilicate glass tubing, this vial component is highly specialized as the top features a large extended flange so the vial can seat appropriately inside the device. The inner diameter is precisely controlled to allow for plunger functionality similar to a syringe system. Corning produces the glass tubing raw material for these unit dose, mono dose or single dose nasal inhalation systems using standard pharmaceutical injection grade borosilicate glass with built in dimensional design characteristics to successfully meet the challenging requirements of these emergency solitary nasal dose appliances.
