Dissolution tester PTWS 4000

for tabletsautomaticbenchtop

PTWS 4000 is the only tablet dissolution testing instrument available to support vessel sizes up to 4 liters for pool test applications of highly concentrated samples. PTWS 4000 contains six stirred glass vessels with a volume of approx. 4 liters each in a single row in the front side of the instrument. Furthermore, it offers two additional, unstirred 1 liter vessels to take a blank and/or a reference standard in a second row on the back side of the instrument. PTWS 4000 is fully compliant to the current USP and EP pharmacopeia. PTWS 4000 can also handle 1 liter and 2 liter USP/EP vessels using the same Monoshaft™ stirring tools. The adapters to use smaller vessels are included in the standard scope of supply. This makes the PTWS 4000 one of the most flexible dissolution testing instruments available. The PTWS 4000 is an ideal instrument for either manual sampling or basic automation. The „six-in-line“ vessel configuration means optimal access to the samples for subsequent analysis. Its automated lift-up system moves the drive head into an upper position to remove the vessels and allows for easy cleaning. The U-shaped water bath is separate from the main frame of the instrument and the built-in circulation pump is mounted on a spring loaded assembly to eliminate the transfer of vibration to the dissolution vessels.
