  • Patent number: 11781950
    Abstract: In one aspect, a system for controlled temporal extraction of ingredients of a pharmaceutical dosage form is disclosed, which comprises at least one reservoir for storing a fluid comprising a solvent, a cell having at least one inlet port in fluid communication with said reservoir for receiving a flow of the fluid from the reservoir and an outlet port through which fluid can exit the cell, where the cell is configured to receive a pharmaceutical dosage form. The system can further include an in-line heater disposed in proximity of the inlet port of the cell for heating the fluid to an elevated temperature prior to entry thereof into the cell, and a pump for causing fluid circulation between said reservoir and said cell.

  • Patent number: 9255865
    Abstract: The invention provides a system and method for dissolution testing. The system includes multiple dissolution vessels and a dose carrier positioned above the dissolution vessels. The dose carrier holds multiple removable carousels that receive individual doses for dissolution tested. Carousels that receive tablets or sinkers typically have a first configuration, while carousels that receive baskets typically have a second configuration. The two different configurations of carousels are interchangeable on the same dose ring. The system further includes a drive head positioned above the dose carrier, the drive head having a basket arbor and a mixing paddle removably and interchangeably attached. A pipettor integral with the system transfers sample aliquots having volumes in the range of 50 ?l to 1 ml from the dissolution vessels to wells of an external receptacle.
