USP 5 skin patch surface dish holder with 17 mesh (on pulp tray)

Equipment: This QLA USP5 skin tested device is sold as a borosilicate glass dish with 17 PTFE mesh, gathered together with PTFE pellets. Patch up to a diameter of 90mm can be used for testing. It is compatible with all dissolution bath brands and fully complies with USP specifications. Method: USP Method 5 (on a tray) or USP Method 6 (rotating cylinder) is used for transdermal or skin allergy testing. The method used on the paste tray involves placing the skin patch between a glass tray and an inert polytetrafluoroethylene mesh. This is placed at the bottom of the container, with the grid facing upwards and below the mixing shaft. Unlike dissolution tests, transdermal testing is conducted at 32 ° C to reflect the lower temperature of the skin. Other variables, such as height setting, sampling requirements, and dissolution test, are the same.
