James Alexander glass ampoules offer all of the advantages that make glass the indispensable package for many applications.
Not only will our glass ampoules extend product shelf life, they are also ideal whenever tamper resistant packaging is a must, when the formulation is sensitive to environmental exposure, or when the application calls for a two part system where the materials need to be mixed immediately prior to use. With a simple press or squeeze, the user activates the glass ampoule without even realizing that the package contains an ampoule.
James Alexander’s crushable glass ampoule can be made of USP (United States Pharmacopeia) type I or type III glass. USP type I glass is a borosilicate glass composed principally of silicon dioxide and boric oxide, with low levels of the non-network forming oxides. It is a chemically resistant glass exhibiting low leachability and a low thermal coefficient of expansion.
USP type III glass is commonly called “soda lime” glass. It is composed of relatively high proportions of sodium oxide and calcium oxide. Soda lime glass melts at a lower temperature, which makes it easier to mold into various shapes. This glass is less chemically resistant than USP type I glass and is typically used in applications where a slight variation in the pH will not affect the contents of the ampoule.
James Alexander’s crushable glass ampoules come in a variety of diameters to meet varied packaging needs. Standard diameters are 7.0 mm and 8.0 mm. All diameters have tolerances of +/- 0.25 mm. The length of a sealed glass ampoule can be varied from approximately 30 mm (1.2 inches) to more than 100 mm (3.9 inches). Tolerances for sealed ampoule length are typically +/- 1.5 mm.
Custom diameters and sizes are available for customers with nonstandard needs. When designing packages requiring glass ampoules, James Alexander recommends that customers attempt to utilize standard diameters in order to minimize lead times and cost.
James Alexander has also developed the capability of filling crushable ampoules with powders, with reproducible fill volumes as low as 50 milligrams. Powder ampoules are ideal for diagnostic test kits and a variety of other applications. Since ampoule quality and fill volume reproducibility are highly dependent on the characteristics and consistency of the particular powder or crystal, a small pre-production sample run is highly recommended.
