DISSOLUTION SINKERS
Floating dosage forms rarely dissolve at a reproducible rate. Using a sinker together with Apparatus 2 fixes the dosage form to a certain point and aids reproducibility. Sinkers can also be useful where dosage forms may stick to the sides of the vessel. Our sinkers can also be used in disintegration testing to prevent floating dosage forms.
