A European pathology consumables distributor changed slide suppliers because slides from its previous source varied slightly in size from batch to batch, which caused handling problems on automated staining equipment at its hospital customers. Jiangsu Huida Medical Instruments supplied colour frosted slides and adhesion microscope slides under the distributor's own brand, added three specific inspection steps to control the dimensional problem, and delivered the first consignment on schedule. The account has been reordering on a regular cycle for more than five years.
