Revisions to the USP General Chapter <711> Dissolution are now official and the new standard for Performance Verification Testing is the only official standard as of May 1, 2023!
In our continued effort toward comprehensive qualification of dissolution instruments, we have developed a new product, Dissolution Performance Verification Standard (DPVS) – Prednisone tablets to create greater reassurance in the performance qualification of Dissolution Apparatus 1 and Dissolution Apparatus 2 using Performance Verification Testing.


Based on the studies that have been performed, the new product is more sensitive to operational and mechanical variables of instrument setup, less sensitive to media degassing, and delivers more consistent results.
