A laboratory centrifuge is a piece of laboratory equipment, driven by a motor, which spins liquid samples at high speed. There are various types of centrifuges, depending on the size and the sample capacity.
Large centrifuges are used to simulate high gravity or acceleration environments (for example, high-G training for test pilots). Medium-sized centrifuges are used in washing machines and at some swimming pools to draw water out of fabrics. Gas centrifuges are used for isotope separation, such as to enrich nuclear fuel for fissile isotopes.
It is a commonly used biomolecular analysis technique used to evaluate sample purity, to characterize the assembly and disassembly mechanisms of biomolecular complexes, to determine subunit stoichiometries, to identify and characterize macromolecular conformational changes, and to calculate equilibrium constants and thermodynamic parameters for ...
used in photochemical analysis and quantitative estimation of substances such as blood sugar, creatinine, and hemoglobin. Burette: used to measure the amount of acid or alkali used in titration: General laboratory stands, racks, filter paper, reagents, etc. Induction coils: as a source of high voltage electricity Cathode ray oscilloscope ...
Benchtop fixed-angle centrifuge, or swinging bucket centrifuge Intact (eukaryotic) cells, macroscopic debris Varies depending on sample Gently lysed cells (e.g. dounce homogenizer) 600 x g 10 min Benchtop fixed-angle centrifuge, or swinging bucket centrifuge Nuclei Cytosol, non-nuclei organelles Supernatant of previous row 15,000 x g 20 min
An ultracentrifuge is a centrifuge optimized for spinning a rotor at very high speeds, capable of generating acceleration as high as 1 000 000 g (approx. 9 800 km/s²). [1] There are two kinds of ultracentrifuges, the preparative and the analytical ultracentrifuge.
