Glass tubes for primary pharmaceutical packaging
Glass has always been the material of choice for manufacturing pharmaceutical packaging. The main reason is that glass is an inert material that prevents gases and other volatile substances, for example, from penetrating the wall of the glass and entering the pharmaceutical product. However, different qualities of glass are available. Glass for primary pharmaceutical packaging must fulfill a wide range of requirements stipulated in the latest versions of regulations and pharmacopoeia as well as international standards such as ISO 720, ISO 719 und ASTM E 438. Dispensaries categorize glass into three types (I to III). Type I represents the highest quality level and packaging from this category is recommended for parenteral pharmaceutical solutions whereas type III glass is manufactured for specimens that are not intended for parenteral administration.
