摘要:
The invention is an automated robotic system for the production and testing of formulations at a very high throughput. It is an integrated system of hardware and software capable of preparing and evaluating hundreds of emulsions per day. The system can formulate aqueous solutions (SL), oil in water emulsions (EW), suspo-emulsions (SE), micro capsule suspensions (CS), micro-emulsions (ME), and suspension concentrates (SC) at the 1 ml to 25 ml scale. The system can process emulsions rapidly in an automated way and enable very flexible formulation recipes to be introduced.The system allows chemists to generate experimental samples of varying recipe and method to be conducted in parallel with projected throughput of up to 1200 formulations processed and characterized per day. Materials and consumables can be distributed from storage storage systems to the work stations where dispensing of ingredients in various states can be performed, including solids, liquids, gels, pastes, suspensions and waxes. The emulsions formed can be characterized using methods including phase diagnosis, turbidity analysis, viscosity and particle sizing using automated test equipment. An integrated module can also perform Tank Mix Compatibility testing in high throughput mode. The modular system allows future processes and tests to be added, either to a station, or as a new station. The software capability includes tracking of processes from start to finish and the integration of analytical data with the as-designed and as-formulated experimental results.

The present invention provides a dissolution test apparatus comprising, a first chamber 2 connected in series to at least a second chamber 10, wherein the first chamber 2 is capable of transferring solid test samples to the second chamber 10 and the second chamber 10 is capable of retaining the solid test samples. Further, the apparatus includes a first reservoir 21 and at least a second reservoir 22 for continuously supplying one or more media into the first chamber 2 and the second chamber 10, respectively, the chambers having stirrers 4, 11 for mixing the solid test samples and the media together. In addition, the second chamber 10 has a filter membrane 45 overlying a base 44 of the second chamber 10, the filter membrane 45 being supported by a filter support 46, the filter support 46 being provided between the filter membrane 45 and the base 44 of the second chamber 10 to prevent distortion of the filter membrane 45. Processors 5, 16, 20 for analyzing an effluent from the chambers are also provided.
摘要:
Method for handling blood samples (32) wherein a blood sample is absorbed into a filter paper (30) and a sample piece (36) is taken from the filter paper from the opposite side of the absorption side. The sample piece is placed in a sample well of an uncoated micro titration plate (45) and is dissolved in a liquid so that a sample solution is formed in the well. The sample solution is transferred to a second micro titration plate (52-54) coated for the analysis. The apparatus comprises a camera (43), which identifies the filter paper (30), locates the blood sample (32), and informs the punch (47) of the location of the sample. The filter paper (30) is placed in a package, (22) having openings (25) for absorbing and punching of the sample and the covering (23) is provided with a bar code (29).

An automated apparatus for testing a sustained release drug according to a preselected program having a movable dissolution chamber, a first flow path connecting said chamber to a buffer reservoir, a second flow path connecting said chamber to a fluid collection reservoir and a third flow path connecting said chamber to a wash reservoir, and programming means for activating fluid flows between said reservoirs and said dissolution chamber in accordance with a preselected program.
摘要:
An automatic filter changer that automatically inserts and removes a filter from a fluidic path. Filters are introduced into the automatic filter changer in stacks. The lead filter and each stack is removed from its respective stack one by one by a filter separator. The separated filters are deposited onto a shuttle plate which moves the filters into their respective fluidic paths. Fluid couplers connect to each filter to complete their respective fluidic paths and allow fluids to be filtered before sampling. Once collection of the samples is complete, the filters are removed from the fluidic path and discarded or saved for reuse. The shuttle path is returned to its original position to receive new filters to repeat the process again. A graphic user interface is provided to allow the user to program a specific set of instructions to automate the entire process.

An infrared spectrometer system with automated tablet sampling includes an infrared spectrometer providing a modulated output beam to a sample position, and reflected and transmitted light detectors. A tablet holding wheel is mounted to advance multiple tablets one at a time to the sample position. The tablet holding wheel includes a tablet wheel base having a plurality of transmission openings therein in a circular pattern around a central axis of the base, grippers adjacent to each of the transmission openings that are movable inwardly and outwardly, and a cam ring mounted to and rotatable with respect to the tablet wheel base, the cam ring being operatively engaged with the grippers to move the grippers outwardly and inwardly to engage and hold tablets over the transmission openings. The tablet holding wheel can be automatically rotated to move a tablet to the sample position where analysis can be carried out, to advance the tablet wheel to move the next tablet into position for analysis, and to repeat the process until all of the tablets have been analyzed.
