The PTWS 620 is a 6 + 2 position, single drive tablet dissolution testing instrument for solid dosage forms as described in USP chapter <711/724> and EP section<2.9.3/4> as well as the DAB/BP and Japanese Pharmacopeia section <15>. The USP monograph <1092/2.4.2> lists visual observation of the dissolution behavior as essential for identifying variables in the formulation or manufacturing process. The six vessels in the front row of PTWS 620 offer optimal visibility of the samples.
