ERWEKA USP 4 Close-loop Dissolution Tester Offline System

Introduction:

• The system is capable of performing dissolution experiment on different formulation based on the principle of U.S. Pharmacopeial Convention (USP) apparatus 4 (Flow-through cell).

• Flow-through cell is an improvement to the traditional dissolution testing method. As a USP apparatus, the system meets the requirement of all existing analytical method. By changing the flow-through cell and flow rate of dissolution media, the system can be used to analyze novel and complex formulation.

• Flow-through cell is recommended by USP for the determination of difficult-to-dissolve and sustained release drug. These drugs required a large volume of dissolution media, which is limited by the traditional USP stirring method. On the other hand, flow-through method has no limitation on dissolution volume, which makes it ideal to overcome the harsh sink condition with larger dissolution volume.

• Because of the supply of fresh media, capability of changing pH value rapidly and continuous sampling, flow-through method provides consistent sink condition.
