Abstract
Improved sampler apparatus and methods for dissolution testing include a controller that determines whether several different dissolution testing methods can be performed concurrently by the sampler and controls the sampler in response to the determination; fluid delivery apparatus adapted to pierce a septum and to deliver fluid to or from a collection receptacle through a first aperture, and to permit air flow to or from the collection receptacle through a second aperture; a syringe pump including a distributor having apertures through which fluid flows into and out of the pump chamber, the piston of the syringe pump being moveable adjacent the apertures; and/or a leak sensor responsive to the presence of spilled fluids.
