A separator is laboratory equipment that is used to separate two immiscible liquids or solids of different densities. It is commonly used in chemical, pharmaceutical, and biotech industries, as well as in research and development laboratories. Separators are also called centrifugal separators because they use centrifugal force to separate the components.
A separator works on the principle of differential sedimentation, where the particles with higher density sediment at a faster rate than those with lower density. The separator consists of a rotating bowl and a motor that drives the bowl. The mixture of the two components is introduced into the bowl through a feeding system. As the bowl rotates at high speeds, centrifugal force is generated, which causes the denser component to move toward the outer edge of the bowl, while the less dense component moves toward the center.
Once the components are separated, they can be collected through separate outlets on the separator. The separated components can then be further processed or analyzed as needed. Separators are available in various sizes and capacities to accommodate different laboratory needs.
There are various types of separators, including disc-stack separators, decanter centrifuges, and tubular bowl centrifuges. The choice of separator depends on the specific application and the properties of the components being separated. Disc-stack separators are commonly used for separating liquids with small solid particles, while decanter centrifuges are used for separating liquids with high solid content. Tubular bowl centrifuges are used for separating liquids with low solid content.
Separators are essential laboratory equipment that can be used for various applications in different industries. They are designed to separate two immiscible components of different densities and are available in different types and sizes to meet specific laboratory needs.
