Compact 8-Station Dissolution Testing Instrument

The PTWS 800D is an 8 position, single drive compact tablet dissolution testing instrument for solid dosage forms as described in USP chapter and EP section as well as the DAB and Japanese Pharmacopeia section . It is supplied with a staggered start feature for each of the eight positions. The upper drive is electronically controlled to offer two positions: an upper cleaning and a lower working position. The electronically driven lift mechanism is located centrally above the water bath. This assures that the whole lift drive mechanism is positioned in a way so that the tool shafts are always kept parallel and at a 90° angle to the vessel walls when in the working position.     
     
The PTWS 800D features the 3CS three-point individual centering system for each dissolution vessel. The vessels are held in position by three adjustable noses and are inserted into the instrument support framework. The access points for sampling as well as the openings for the tools are contained in an auxiliary, low evaporation, vessel cover.
