Superspeed centrifugation is a technique for spinning samples at high speeds, up to 10,000s of revolutions per minute. The spinning creates very high centrifugal forces, causing different particles in the samples to move at different speeds, depending on their size, shape and density. In biochemical applications of centrifugation, the particles can vary in size from whole cells (e.g. from bacteria, yeast, insect or mammals), to sub-cellular particles (e.g. various pieces of broken cells), to smaller assemblies of molecules (e.g. proteins, nucleic acids, lipids, inhibitors, drugs and nanomaterials) with different net sizes and compositions.

超高速离心法是一种高速旋转样品的技术，最高可达每分钟10000转。旋转产生非常高的离心力，导致样品中的不同颗粒以不同的速度移动，这取决于它们的大小、形状和密度。在离心法的生化应用中，颗粒大小不一，从整个细胞(例如细菌、酵母、昆虫或哺乳动物)，到亚细胞颗粒(例如各种破碎的细胞)，再到具有不同净尺寸和组成的较小的分子集合(例如蛋白质、核酸、脂类、抑制剂、药物和纳米材料)。
