Dissolution Testing for USP method 4

The SOTAX CE 7smart is the 4th generation of the Flow-Through cell instrument designed over 35 years ago by Dr Langenbucher in collaboration with SOTAX.

In this USP 4 method a test sample is placed in a specially designed cell through which media is pumped at 37°C. The eluate is filtered upon leaving the cell and can then either be analyzed by UV/UVFO or collected for HPLC. The type of cell is chosen to suit the dosage form and it is permanently maintained at 37°C in a water jacket. Parameters such as flow rate, quantity of dissolution media and filtering porosity are defined during method development
