Manufactured for precise dissolution tests with automated samples and filtering mechanisms is the RT3-AT Reciprocating Cylinder Dissolution System. This unit has an integrated coaxial bracket that enables fast mount replacements for holders alongside automatic vessel lids that protect against evaporation over time. The design incorporates a single-piece water bath which provides uniform heating properties and full drainage. The equipment operates with a high-precision sampling pump as well as an advanced Teflon pipeline system which prevents sample adsorption and maintains accurate results. Users can adjust the parameters for reciprocating stroke position alongside rate immersion duration and drainage duration according to FDA 21 CFR Part 11 standards.
