Title: Basics of sterile compounding: bubble point testing. Author: Thoma L. Journal: Int J Pharm Compd; 2014; 18(1):54-7. PubMed ID: 24881342. Abstract: Compounding pharmacies that compound sterile preparations must choose sterile filters that are approved for human use. They may rely on the filter manufacturer's Certificate of Quality to ensure the sterile filter is pyrogen free and has been tested for bacterial retention. The Certificate of Quality from the filter manufacturer also contains other useful information about the filter such as: flow rate and maximum pressure drop, thermal and hydraulic stress, and membrane results of the initial integrity test performed on the filter membrane with water, if a hydrophilic membrane. This article discusses the integrity test, which is often called the water bubble point test.[Abstract] [Full Text] [Related] [New Search]
