The Hanson Research Dissoette II is a programmable autosampler that handles a wide variety of dissolution applications and requirements. On command it withdraws, measures, and dispenses an aliquot from a dissolution test station into a carousel from which the sample may be automatically directed to a UV flow cell. The system may work with Hanson Research SR8-Plus Dissolution Test Station. Most commercial dissolution sampling systems use peristaltic pump movement of dissolution fluid into a collector or through a UV flow cell. The Dissoette was developed to avoid the volumetric inconsistency of the peristaltic pump, and provide an all polyfluorocarbon/ glass/ stainless environment to minimize drug absorption.
