Collapse test basket and collapse detector

摘要

PROBLEM TO BE SOLVED: To provide a disintegration test basket and a disintegration detection device having improved detection accuracy at the time of disintegration of a solid preparation. SOLUTION: A disintegration test basket 2 is immersed in a test solution while holding a solid preparation S1. The disintegration test basket 2 has a cylinder 20 having a bottom net 20a and a cylinder wall 20b extending in the vertical direction VD and capable of holding the solid preparation S1 inside, and a first light whose detection range is the first region Ar1 in the cylinder 20. It has a sensor 21 and a second optical sensor 22 whose detection range is a second region Ar2 above or below the first region Ar1. [Selection diagram] FIG. 5
