The PT-DT8S instrument is a low head, flip back, staggered stirrer start Dissolution Bath which offers 8 stirred positions, integrated manual tablet drop magazine, self-sealing and centring vessel covers placed within the drive head, audible signal for operator information and vibration free water bath assembly. The DT8S i designed in complaince to the valid USP <711> and EP <2.9.3> Pharmakopoeia. This instrument may be used  also for automation. The standard supply scope includes batch coded glass vessels (1 litre), coded mono stirrer shafts with attachable stainl. steel adapter with paddle blades (basket, TC etc. optional), stirrer depth and centring gauges. The 4+4 arrangement of the vessels reduces the footprint to approx. 70 cms and the additional 7th./8th. stirrer allows more flexibility including temperature monitoring in a vessel while still under test conditions, i.e. with a rotating paddle or basket inserted, or it may be used for Blank and Reference Media. Using the PT-DT8S within an automated system offers the operator full access to the vessels before and at the end of a run as the complete drive housing is lifted backwards, assisted by the easy-lift assistance. Manual and automated sampling is done through the drive head which is equipped with special holes to allow the PT-MDS Manual Sampling System or any tubing installation to pass. The second hole inside the head is used to drop the tablets onto the built-in tablet drop magazine. The special design, in which the water bath is placed on shock absorbers to the instrument's chassis, virtually eliminates any vibration transfer from both within the instrument but also from any unit placed onto the same bench. Even the built-in circulation pump is spring loaded for absolute vibration free operation. The measurable vibration is even lower as of systems which use a separate heating system if this is placed to the same bench. For easy and fast maintenance the pump and mains power entry are placed to both sides of the machine. Pump, Heater, Sensor, Mains Supply Board are accessible without to move the bath off its position. This saves you the necessity to do a USP Suitability Test using RS Tablets after instruments maintenance. Each stirrer shaft may be started to rotate inside the vessel after the tablets has been introduced either manually or by the magazine if simultaneous start is required.
