2010 GMP claims that the production of ophthalmic preparations should be in accordance with sterile preparation. The use of sterile production process brings big challenges to the sterilization of packaging materials such as bottles of eye drops. As the polymer material (such as PE or PET) the packaging used can only be dealt with low temperature sterilization, while traditional low temperature sterilization methods, such as EO or radiation sterilization can not make this sterilization process integrated into the sterile production process of eye drops because of the sterilization process and equipment features. To solve this problem, Tailin developed sterilizing equipment for eye drops bottles - STP2000V VHPS Vacuum Sterile Transfer Passageway. STP2000V VHPS Vacuum Sterile Transfer Passageway use vaporized hydrogen peroxide sterilization to sterilize inside and outside surface of eye drops bottles, which enables the sterilized body to reach the level no higher than 10-6 sterility assurance level (SAL). This method is fast, non-toxic and can work under a low temperature.
