You'll find distinctive types of dissolution test apparatus utilized for dissolution test as per USP. Dissolution technique is explained intimately right here.
The Agilent reciprocating holder apparatus (USP Apparatus 7) is perfect for automated dissolution testing of dosage sorts demanding a change of media, scaled-down volume or maybe more vigorous agitation.
Tablets are tested individually in each tube, and also the test is repeated with added tablets if any fall short to completely disintegrate inside the desired time. Enteric coated tablets are initial tested in simulated gastric fluid for one hour to be certain no disintegration happens, and afterwards in intestinal fluid to confirm complete disintegration.
The Agilent NanoDis Method provides formulation scientists with exact release profiles of APIs applying typical dissolution test apparatus in an automatic, compliant way.
