Developing 503B Test Standards for Ophthalmic Liquids and Oral Medications

Posted July 08, 2021 by Kristin

The FDA’s designation for 503B outsourcing facilities has opened a fast-growing, high-demand segment in the compounding pharmacy market. There is tremendous potential to improve the purity and sterility of both human and veterinary drugs with the use of cGMP, or current Good Manufacturing Practices. While the FDA regulates adherence to the manufacturers’ quality, training, and control processes, pharmaceutical manufacturers must determine their own testing protocols and test equipment that make up cGMP.

Real-time Group Refractive Index Measurement Of Fluids Using Interferometry

Posted June 21, 2017 by Kristin

Abstract — Maintaining proper chemical composition of fluids is an important control parameter for a variety of different production processes. This is especially critical in the medical device manufacturing to maintain high quality standards. One method to monitor fluid composition is to measure its refractive index.
