Pharmatest USA PTWS 100D



The PTWS 100 is a 6 position, single drive compact tablet dissolution testing instrument for solid dosage forms.          
It is supplied with a staggered start feature for each of the six 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.
