14 Vessel Dissolution Testing 

The PTWS 1420 is a 14+2-position, “dual drive” compact 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 BP, DAB and Japanese Pharmacopeia section <15>. The instrument features 14 testing positions and includes two additional standard size vessels for media refilling and reference standard media. PTWS 1420 features independent stirrer speed control for the left and right half of stirrers.

Perfect Biowaiver Solution

PTWS 1420 is the first tablet dissolution testing instrument from Pharma Test featuring 14 full size stirred vessel positions. The vessels are arranged in a two times 6+1 configuration.  This way not only your samples but also the standard or reference media will be heated and stirred by the instrument. In addition PTWS 1420 features two additional heated full size vessels to store the replacement media for systems including an auto sampler. This way also the replacement media, which is filled into the vessels after sampling, always has the same temperature as the test media – eliminating any influence on the dissolution test due to the refilling of cold media. The 14+2 vessel design of PTWS 1420 makes this instrument an excellent choice for Biowaiver applications and offline automated systems.
