Single 12 vessel dissolution bath for use in comparative studies "Biowaivers"

In Biowaiver testing you require dissolution profiles of 12 tablets to be able to calculate the f2 statistic. By using a single bath in a comparative test ("Biowaiver") you can ensure that your result is not affected by any variation in temperature, vibration, stirrer wobble and other issue related to the machines. The PTWS 1220 is a 12 stirred vessel in a 6 + 6 arrangement and 2 extra vessels for media refill.The PTWS 1220 dissolution bath is available also as a DFC1220SP offline semi-automated system including dissolution bath, syringe pumps and fraction collector.

Key features:

  • Fully USP <711/724> and EP <2.9.3/4> compliant

  • 12 stirred positions in a 6 + 6 arrangement, 2 extra vessels for refilling or standard media

  • Rigid motorized lift drive to raise and lower the head

  • Individually coded Borosilicate vessels
