===High-speed centrifuges===
High-speed centrifuges are typically used to harvest microorganisms, [[virus]]es, [[mitochondria]], [[lysosomes]], [[peroxisomes]] and intact tubular Golgi membranes. The majority of the simple pelleting tasks are carried out in fixed angle rotors. Some density-gradient work for purifying cells and organelles can be carried out in swinging-bucket rotors, or in the case of [[Percoll]] gradients in fixed-angle rotors.<ref name="Graham"/> High-speed or superspeed centrifuges can handle larger sample volumes, from a few tens of millilitres to several litres. Additionally, larger centrifuges can also reach higher angular velocities (around 30,000 rpm). The rotors may come with different adapters to hold various sizes of [[test tubes]], bottles, or [[microtiter plate]]s.
