The ERWEKA Flow-Through cell dissolution tester is developed for products which require long term tests (i.e. implants) and / or need a high amount of media due to low solubilty. In configuration as a closed system the Flow-Through cell enables dissolution tests with a low amount of media in order to achieve the necessary testing environment as internationally required. Due to the possibility for easy pH changes, the Flow-Through cell is the perfect unit for IV/IVC testing. It is controlled by a PC with the Disso.net USP 4 dissolution software.
