WebUltracentrifuge The ultracentrifuge is a centrifuge optimized for spinning a rotor at very high speeds, capable of generating acceleration as high as 1,000,000 g (9,800 km/s²). There are two kinds of ultracentrifuges, the preparative and the analytical ultracentrifuge. Both classes of instruments are used in molecular biology, biochemistry and polymer science. WebCentrifugation: Basically all biochemistry laboratories contain one or more centrifuges. The uses of a centrifuge can vary, but it is mainly used for the preparation of protein samples or analytical measurements on purified proteins. These analytical measurements include determining the shape, size and density of the purified protein. WebSep 6, 2024 · The different types of centrifuge are adjusted to the different types of centrifugation: preparative centrifugation, which aims to isolate specific particles, and analytical centrifugation, with which physical properties such as sedimentation rate or molecular weight can be estimated. Thus, centrifuges can be divided into two large groups: merrell ontario boots
