Right after two hrs of operation during the acid medium, withdraw an aliquot of the liquid and continue straight away as directed under Buffer stage. Carry out the Assessment on the aliquot working with an acceptable assay method.
Precisely the same set of dissolution calibration expectations is utilised to check the gear before tests are run. The most typical functioning speed for Apparatus II are 50 rpm for good oral dosage types and 25 rpm for suspensions.
It's got a shaft in addition to incorporates a disk assembly that could maintain the product or service in a means which the surface are going to be leveled Along with the paddle. The paddle is joined with the disk assembly. Its quantity capacity is 900 ml.
