A centrifuge is a device that uses centrifugal force to subject a specimen to a specified constant force - for example, to separate various components of a fluid. This is achieved by spinning the fluid at high speed within a container, thereby separating fluids of different densities (e.g. cream from milk) or liquids from solids.

2024年11月5日 · A centrifuge is a lab instrument for the density-based separation of fluids, gas, or liquid. The idea for the first centrifuge originated with British military engineer Benjamin Robins, who built a device that resembled an arm rotating around an axis to gauge drag on items.

Centrifuge, any device that applies a sustained centrifugal force—that is, a force due to rotation. Effectively, the centrifuge substitutes a similar, stronger, force for that of gravity. Every centrifuge contains a spinning vessel; there are many configurations, depending on use.

2023年6月29日 · A centrifuge is a device used to separate components of a mixture on the basis of their size, density, the viscosity of the medium, and the rotor speed. The centrifuge is commonly used in laboratories for the separation of biological molecules from a crude extract.

2023年5月23日 · What is a centrifuge? A centrifuge is a powerful device utilized for separating and purifying mixtures by employing centrifugal force. It effectively separates particles based on their size, shape, density, viscosity, and rotor speed.

2024年2月8日 · A centrifuge is an instrument that separates mixture components based on size, density, medium viscosity, and rotor speed. It is commonly used in laboratories to separate biological components from raw extracts.

2020年1月8日 · The term centrifuge can refer to a machine that houses a rapidly rotating container to separate its contents by density (noun) or to the act of using the machine (verb). Centrifuges are most often used to separate different liquids and solid particulates from liquids, but they may be used for gases.

2025年2月13日 · A centrifuge is a device spinning materials at high speeds using centrifugal force to separate them depending on variations in their densities. It works by generating a force pushing heavier particles away that lets lighter particles stay nearer the center.

A centrifuge is a device for separating particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed. In a solution, particles whose density is higher than that of the solvent sink (sediment), and particles that are lighter than it float to the top.
