What our clients say
Trusted by global pharmaceutical innovators, PharGlass delivers validated RTU and sterile primary packaging systems that safeguard drug integrity.
“As a mid-sized injectables manufacturer in the U.S., we recently transitioned to RTU (Ready-to-Use) components to streamline our aseptic filling. PharGlass stands out for its exceptional consistency. Their sterile Type I borosilicate vials exhibit excellent hydrolytic resistance, and the pre-sterilized rubber stoppers pass all extractables and particles testing seamlessly. What truly impressed our QA team was their complete validation documentation, including sterilization certificates and endotoxin data. From initial trial samples to full-scale commercial production, they proved to be a strategic partner, not just a vendor.”
