In United States Pharmacopeia (USP) General Chapter <711> Dissolution, there are four dissolution apparatuses standardized and specified. [6] They are: USP Dissolution Apparatus 1 – Basket (37 °C ± 0.5 °C ) USP Dissolution Apparatus 2 – Paddle (37 °C ± 0.5 °C) USP Dissolution Apparatus 3 – Reciprocating Cylinder (37 °C ± 0.5 °C)

During the dissolution testing, "sink condition" is a mandatory requirement, otherwise when the concentration begins to get too close to the saturation point, even though the total soluble amount still remains constant, the dissolution rate will gradually begin to reduce in significant amounts, enough to corrupt the test results. .

I think it would make the article clearer if "dissolution" was explained. CBHA 03:22, 10 May 2013 (UTC) [] @CBHA: A good suggestion but I disagree. Dissolution testing is a common name used in the Pharma industry, it should be pretty self-evident to most readers what dissolution means even if your not sure or don't work in that field ( a simple Google search can rectify any doubts).
Sample preparation may involve dissolution, extraction, reaction with some chemical species, pulverizing, treatment with a chelating agent (e.g. EDTA), masking, filtering, dilution, sub-sampling or many other techniques. Treatment is done to prepare the sample into a form ready for analysis by specified analytical equipment.
A volumetric flask (measuring flask or graduated flask) is a piece of laboratory apparatus, a type of laboratory flask, calibrated to contain a precise volume at a certain temperature. Volumetric flasks are used for precise dilutions and preparation of standard solutions. These flasks are usually pear-shaped, with a flat bottom, and made of ...
