After centrifugation, all the cell debris has been forced to the bottom of the PCR tube (1), leaving only the DNA in the liquid supernatant (2). The supernatant should look clear, like water. Finally, you will transfer the supernatant into a new PCR using the micropipette. Set the micropipette to 20μL and put on a new tip.

Frank H. Stephenson, in Calculations for Molecular Biology and Biotechnology (Third Edition), 2016 Abstract. Centrifugation is a method of separating molecules having different densities by spinning them in solution around an axis (in a centrifuge rotor) at high speed. It is one of the most useful and frequently employed techniques in the molecular biology laboratory.

Microscopic examination of urine sediment should be part of a routine urinalysis. For centrifugation, 3–5 mL of urine is transferred to a conical centrifuge tube. Urine is centrifuged at 1,000–1,500 rpm for ~3–5 min. The supernatant is decanted, leaving ~0.5 mL of urine and sediment in the tip of the conical tube.
