The Vial Weighing System is a fully enclosed floor standing robot that is integrated with an Azenta Vial Store. The system is compatible with a 280 Position High Density Rack containing 4ml vials. The system weighs empty vials and vials filled with compound. The Vial Store and Vial Weighing System communicate with each other via a web service.

The Vial Store presents a rack to the Vial Weighing System and informs the system that the rack is ready to be processed. Each vial is picked by the robot, barcode scanned, cap removed and weighed on a 5-place balance. Once all vials in the rack have been weighed the rack is automatically returned to the vial store. Vial weights and barcodes are uploaded to a LIMS system.
