Compact Dissolution Testing Instrument
The new PTWS 800D compact dissolution testing instrument is based on the design of the popular PTWS 100D and features 8 stirred positions in either a 2×4 or a 4×2 configuration. The dissolution testing instrument still maintains a minimal bench space requirement of just 45cm by 75cm (width by depth). Like in the PTWS 100D, a touch screen allows control of the various mechanical features of the instrument such as the tool stirring speed, lift drive and heater. The instrument control is menu driven. Visual signals on the display inform the user of the status of critical instrument parameters, e.g. bath target temperature not reached.
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.
The heating system is contained in a separate stainless steel housing. The connections between the heater and the bath are made by „quick connect“ fittings for easy connection and disconnection. Water is pumped through the system using a powerful, yet quiet, circulation pump. The pump itself is spring mounted (to limit vibration transmission) and the flow-through heater is protected from overloading (overheating in case of control electronics failure) via a thermal fuse as well as a thermo switch for added security. With service and maintenance in mind, access to the compact pump and heater section is easily achieved without having to move the main body of the dissolution testing instrument.
