摘要
The present disclosure is directed to an apparatus and method for studying dissolution of a compact sample. The compact sample is typically a pharmaceutical drug sample. A flow-through apparatus includes a frame defining a flow-through channel, a removable insert having a drug sample, the insert positioned within the frame such that a fluid interacts with the sample when the fluid passes through the flow channel. The frame has an opening on the top side to allow a glass plate, typically a microscope cover slip to be positioned within the frame and allow viewing of the fluid flow and interaction with the drug sample. The hydrodynamics of the fluid flow are either known or computed. Thus, dissolution can be studied and observed in view of hydrodynamic characteristics. Typically, only a small amount of sample is necessary for a study. The flow-through apparatus is designed to fit on a microscopy stage and allow visual observation of the fluid/sample interaction.
