IDS 1000
In-Situ Dissolution Test System

IDS 1000 or Fibre Optic In situ Dissolution System is about the application of direct measurement technology to Dissolution Testing. Traditionally, dissolution testing has been carried out on solid dosage forms using a standard dissolution test apparatus. Samples of the dissolving active within the dosage form are taken for estimation from the dissolution tester either manually, or using more automated means such as a pump which has been connected to a suitable measurement device, usually a UV-VIS Spectrophotometer. Using the IDS 1000 and the WinDiss ARGUS Dissolution Software, not only can the whole process of sample measurement be automated, but can also be self contained, such that there is no need for samples to be pumped out of the dissolution vessels to external measurement facilities such as a Spectrometer, because all that is needed for the measurements to be made is contained within the confines of the instrument itself.

The system control functions are provided by the WinDiss ARGUS Dissolution Software a fully 21 CFR part 11 (GAMP) compliant software package suitable for in-situ, closed loop and off-line system operation.
