Fractionation System / Density Gradient Fractionators

Fractionation can be caused by a variety of chemical, biological, or physical processes and is employed in various areas of science, engineering and technology. Fractionation systems are designed to separate an analyte from a sample into equal portions or fractions. It does so in accordance with either the analytes physical or chemical properties, such as by size, density, or bonding ability. In column chromatography, for example, fractionation occurs by difference of affinity whereas in cell fractionation, the cells components are fractioned out by difference in mass. Fractionation instruments provide hands-off, programable, and repeatable options for separating desired samples.
