A method of separating a solid/liquid mixture by rotating it at high speed in a cylindrical container. The solid will remain on the sides (through centrifugal force) while the liquid goes to the drain. Centrifugation is also used in extracting cannabinoid-rich substances from cannabis. A cannabis extraction centrifuge is an industrial centrifuge that continuously separates the biomass from the solvent with the THC oil absorbed in it. A horizontal decanter centrifuge exerts over 3,000 times the gravity force to separate the solvent’s depleted cannabis cuttings.

centrifugation (noun)
the process of - centrifuging
Centrifugation (Wikipedia)

Centrifugation is a mechanical process which involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity and rotor speed. The denser components of the mixture migrate away from the axis of the centrifuge, while the less dense components of the mixture migrate towards the axis. Chemists and biologists may increase the effective gravitational force of the test tube so that the precipitate (pellet) will travel quickly and fully to the bottom of the tube. The remaining liquid that lies above the precipitate is called a supernatant or supernate.

Laboratory centrifuge

There is a correlation between the size and density of a particle and the rate that the particle separates from a heterogeneous mixture, when the only force applied is that of gravity. The larger the size and the larger the density of the particles, the faster they separate from the mixture. By applying a larger effective gravitational force to the mixture, like a centrifuge does, the separation of the particles is accelerated. This is ideal in industrial and lab settings because particles that would naturally separate over a long period of time can be separated in much less time.

The rate of centrifugation is specified by the angular velocity usually expressed as revolutions per minute (RPM), or acceleration expressed as g. The conversion factor between RPM and g depends on the radius of the centrifuge rotor. The particles' settling velocity in centrifugation is a function of their size and shape, centrifugal acceleration, the volume fraction of solids present, the density difference between the particle and the liquid, and the viscosity. The most common application is the separation of solid from highly concentrated suspensions, which is used in the treatment of sewage sludges for dewatering where less consistent sediment is produced.

The centrifugation method has a wide variety of industrial and laboratorial applications; not only is this process used to separate two miscible substances, but also to analyze the hydrodynamic properties of macromolecules. It is one of the most important and commonly used research methods in biochemistry, cell and molecular biology. In the chemical and food industries, special centrifuges can process a continuous stream of particle turning into separated liquid like plasma. Centrifugation is also the most common method used for uranium enrichment, relying on the slight mass difference between atoms of U-238 and U-235 in uranium hexafluoride gas.

    What is this "Wiki" & how does the cannabis community benefit?

    The Green CulturED Wiki enables you to explore, learn, and share through a knowledge base tailored to the cannabis industry. It functions like an encyclopedia, lexicon, glossary, wiki, or dictionary. This tool is useful for industry learners and professionals to learn more about resources, programs, and terms specifically in the cannabis sector.

    Yes, new terms can be added by crafting individual entries, each with its own dedicated page and unique URL. By sharing resources, information, and industry information, users are able to foster community, growth, and learning. Once submitted, a glossary term is reviewed by the Green CulturED team, which will then approve or deny the submission. 

    While the Green CulturED Community Wiki does not impose specific content restrictions, it is essential to adhere to general web content guidelines, which include avoiding misinformation and respecting copyright laws. For cannabis-related glossaries, it’s critical to ensure the accuracy and legality of the information presented. In addition, common courtesy and “netiquette” are part of our community user agreement, and it is crucial to maintain those levels of respect when adding new terms, comments, etc.

    Glossary term categories serve as a reference tool that enhances usability, navigability, and educational value by organizing terms into groups such as industry brands, consulting firms, and seed banks.

    The Green CulturED Wiki supports comments on individual glossary terms, enabling users to engage in discussions or leave feedback. This feature fosters collaborative learning and knowledge sharing within the cannabis community.
    If you encounter incorrect or outdated information, please contact the site administrators directly or use the commenting feature to report inaccuracies for review and correction. Green CulturED Wiki allows for revisions, enabling updates and corrections.
    Green CulturED Wiki utilizes user rights and capabilities for managing and reviewing user-contributed terms. Administrators can set specific permissions and establish review processes according to their policies.
