Dissolution Testing USP 1/2/5/6

Dissolution is a test used by the Pharmaceutical industry to characterize the dissolution properties of the active drug, the active drug's release, and the dissolution from a dosage formulation. Different dissolution testing methods are described in USP, Ph.Eur., and other internationally harmonized Pharmacopeia as well as in FDA guidelines. Whereas standard tablets are typically tested according to the paddle method (USP 2), swelling or floating dosage forms such as capsules are tested using the basket method (USP 1). Paddle-over-disk (USP 5) and rotating cylinder (USP 6) methods are used for transdermal dosage forms.

100% unattended execution of multiple dissolution tests - from media preparation to self-cleaning of the entire system between test runs. Available in different analytical configurations for offline collection of samples, online UV-Vis measuring for immediate dissolution results or as an UV On-/Offline combination.
