The system contains 3 viscometers that take measurements of 3 different size sample jars. The jars are loaded into the system and their locations are entered on the UI. Once the user presses start the Epson robot arm picks the sample, scans the barcode, and places it into one of the appropriate shuttles. The shuttle then moves under the viscometer where a measurement is taken. Once the measurement is finished the shuttle moves back to the Epson arm and the sample placed back to the rack. The viscometer lowers into a wash bath where the geometry is washed and dried.
The viscometers can be setup to use either all the same jar type or a combination of different types. Shuttles on magnets and quick release airlines and racks are colour coded as to provide clear feedback on which jar size each viscometer is setup to use.
