Large volume dissolution testing instrument for pool test applications.
6 + 2 Dissolution Tester
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 <711/724> and EP <2.9.3/4> pharmacopeia.

Various Vessel Sizes Usable
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.
Various Vessel Sizes in the PTWS 4000
Automated Lift Drive
The instrument features an automated lift system for the instrument head with programmable working positions to support different types of dissolution testing tools.
A temperature sensor probe is included to measure the medium temperature directly inside the vessels. Optionally a pH probe can be connected as well.
The standard testing method filing system eases the programming of sampling information. Each of the stirrer shafts can be withdrawn or started in a vessel at any time. This offers the possibility of a staggered start for manual and automated operation. The depth setting of the stirrers can easily be altered to meet the parameters of new tool setting, as is required for transdermal cylinders.
