A pellet in a centrifuge refers to the compact mass of particles that accumulates at the bottom of a centrifuge tube after the sample has been spun at high speeds. The centrifugal force causes denser components, such as cells, organelles, or precipitates, to settle while the less dense components remain in the supernatant. After centrifugation, the supernatant can be carefully removed, leaving the pellet for further analysis or processing.
What else can I help you with?
What is the need for centrifuge in DNA isolation?
Centrifuge is needed in DNA isolation to separate the DNA from other cellular components such as proteins, RNA, and cell debris based on their size and density differences. By spinning the sample at high speeds, the centrifuge helps to pellet the DNA at the bottom of the tube, allowing for the isolation and extraction of pure DNA.
What is the reaction force to centripetal force in a centrifuge?
The centripetal force is the force with which the centrifuge pushes some object inwards. The opposite force, of course, is the object pushing the centrifuge outwards.
What instruments is used to spin liquids to separated compounds?
A centrifuge is used to spin liquids into separate components.
Does centrifuge fling things outward or inward?
A centrifuge flings things outward. When the centrifuge spins rapidly, the centrifugal force pushes objects away from the center, causing them to separate based on their density.
What is the best speed to separate a soil sample in a centrifuge?
Very high speed is the best speed to separate a soil sample in a centrifuge.
What does centrifuge mean in science?
Centrifuge is both a noun as well as a verb. A centrifuge is a machine used to spin liquid solutions at high speeds, which causes undissolved particles in the liquid to collect and form a pellet, making them easier to remove. To centrifuge a liquid means to subject it to centrifugation.
What is the function of the alcohol in DNA extraction?
DNA is not soluble in isopropyl alcohol. It will precipitate out when you add this solvent. Once out of solution you can centrifuge it down and collect the pellet of DNA.
The order in which cellular components will be found in the pellet when homogenized cells are treated with increasingly rapid spins in a centrifuge?
The correct order in which cellular component will be found in the pellet when homogenized cells are treated with increasingly rapid spins in a centrifuge is a nucleus, mitochondria, and ribosomes. Bound ribosomes generally synthesize membrane proteins and secretory proteins.

Who developed the centrifuge?
Antonin Prandtl, however Gustof de Laval invented the first "Modern" centrifuge. http://en.wikipedia.org/wiki/Centrifuge
What is centrifuge swing-out rotor?
A Centrifuge Swing-out Rotor is a part of a centrifuge which attaches to the motor and holds the sample tubes. A swing-out, as opposed to a Fixed Angle rotor, has holders that move from vertical to horizontal as the centrifuge speeds up.
How motor in centrifuge works?
centrifuge is a system which is used to separate the water from the diesel.
Order in which cellular components are found in he pellet when homgoonized cells are treated with increasingly rapid spins in a centrifuge?
Whole cells and nuclei;Mitochondria, lysosomes and peroxisomes;Microsomes (vesicles of disrupted endoplasmic reticulum); andRibosomes and cytosol.taken from: http://en.wikipedia.org/wiki/Differential_centrifugation
What is the centrifuge tube used for?
A centrifuge is used for separating components in a liquid that have different weights.
How much is a centrifuge?
A good centrifuge, such as the Eppendorf 5702 Series, will cost you upwards of $2,000.
What is the structure and function of a serofuge?
A serofuge is a small centrifuge specifically designed to separate serum from cells and to complete blood cell washing procedures. Like a centrifuge, a serofuge has holes to insert the centrifuge tubes in, a lid to protect both the samples and experimenter in case of malfunction, and a way to set the centrifuge speed and way to turn the centrifuge on and off.
What is the reaction force to centripetal force in a centrifuge?
The centripetal force is the force with which the centrifuge pushes some object inwards. The opposite force, of course, is the object pushing the centrifuge outwards.
