Glass tubes for primary pharmaceutical packaging

Glass has always been the material of choice for manufacturing pharmaceutical packaging. The main reason for this is, that glass is known to be an inert material. For example, it prevents gases and other volatile substances from penetrating through the glass wall and entering the pharmaceutical product, and it also reduces the likelihood of drug-container interaction. However, different qualities of glass are available. Glass for primary pharmaceutical packaging must fulfill a wide range of requirements. Testing and classification procedures are described in the latest versions of regulations and pharmacopoeia as well as international standards such as ISO 719, ISO 720 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. glass cartridge
