Arnold H. Beckett, Tlnh T. Quach Improved Hydrodynamics for USP Apparatus 2 Biovail Corporation /l1te171fltionol, Toronto, Conadn Glenn s. Kurs VnnKellndltstries, /11( . Edison, NJ Abstract In spite of irs growing importance in tbe modern Dissolution InboraUJry, USP Apparatus 2 bas been plagued by many problems of reproducibility and accuracy wbicb lend to wasted time using calibrators even wiJe1J tbf1'e is nothing wrong with the calibrators or the instruments. Tbe primary source of variability bas been found to be ;71 the hydrodynamics of the conv emional cylind11cnl ( USP hemispherical) vessel especially untie.)
Improved Hydrodynamics ... cont. sink conditions, even though there is enough volume of liquid in the dissolution vessel to theo retically provide the desired condition.
