What are Dissolution Vessels?
Good dissolution vessels are critical in obtaining correct and reproducible results and are sometimes overlooked as a key element in the dissolution test.
Any good laboratory detergent should work well to clean vessels. It can be used with hot water and a soft-bristled brush. Rinse with tap water (the hardness does a great job of removing soap residue) followed by a final rinse of purified water. It may also be necessary sometimes to use a towel wetted with methanol to remove really stubborn residues.
