Glass cartridges are the cylinder-shaped containers that combine with a pen dispensing system for the injection of insulin, dental anesthetics, and or other medicines. Cartridge pen systems can be reusable by replacing the glass cartridge after injection which can allow for easy at-home use by patients. Type I borosilicate glass is the raw material of choice for the cylinders in pen cartridge systems because of the stability required to store these medicines safely. Glass Penn Cartridge systems are covered in ISO 13926-1 and 11040-1.
