ABSTRACT:
Discrete robotic sampling apparatus for withdrawing samples of pharmaceutical formulations having particulates therein contained within a plurality of dissolution vessels. The apparatus employs a single sampling probe utilizing a single in-line filter therein. Movement of the probe is guided by a robotic arm controlled by a programmable microprocessor which also controls a reversible pump for flushing the particulates retained by the filter, by means of filtered sample, back into the dissolution vessel, prior to dispensing a portion of the filtered sample into a sample container. The probe is then programmed to be washed with a wash solution prior to inserting of the probe into another dissolution vessel for withdrawing of sample therefrom.
