Mix the urine well and pour 12 milliliters of urine in a clean centrifuge tube. (The physical and chemical analysis can be performed on the urine in the tube before centrifuging or on the urine left in the collection container while the tube is centrifuging.) Cap the tube and centrifuge the urine for five minutes at 450 g. RPMs for different centrifuges can be determined by consulting the nomogram in the manufacturer's manual that comes with the centrifuge. At this speed the sediment will be optimally concentrated without destroying any of the fragile elements in the urine.
