What are the parts of a centrifuge?

Basic centrifuge components include an electric motor, a shaft and rotor heads on which the centrifuge head turns, and a motor- drive assembly. If the centrifuge is refrigerated, a compressor and associated components are included. The entire system is housed within a chamber.

What is a microcentrifuge used for?

Microcentrifuges are used for spinning liquid samples as low as 2 ml or even less at high speeds. The products differ depending upon the sample tube size and the number of sample tubes the microcentrifuges can hold in a run.

What is the difference between a microcentrifuge and a centrifuge?

is that centrifuge is a device in which a mixture of denser and lighter materials (normally dispersed in a liquid) is separated by being spun about a central axis at high speed while microcentrifuge is a centrifuge used in laboratories to separate materials from small samples (especially of biological material).

What is the basic principle of centrifugation?

A centrifuge works by using the principle of sedimentation: Under the influence of gravitational force (g-force), substances separate according to their density. Different types of separation are known, including isopycnic, ultrafiltration, density gradient, phase separation, and pelleting.

What is called centrifugation?

Centrifugation is a method of separating molecules having different densities by spinning them in solution around an axis (in a centrifuge rotor) at high speed. Centrifugation is used to collect cells, to precipitate DNA, to purify virus particles, and to distinguish subtle differences in the conformation of molecules.

What is the process of centrifugation?

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 larger the size and the larger the density of the particles, the faster they separate from the mixture.

Why are microcentrifuge tubes important?

A microcentrifuge is an important piece of equipment for any laboratory, as it is used for spinning a variety of samples at high speed, enabling, for example, the pelleting of nucleic acids or proteins from solution, microfiltration of small aqueous samples and gathering liquid into the bottom of a tube to avoid …

Why is centrifugation used?

Centrifugation is a technique that helps to separate mixtures by applying centrifugal force. A centrifuge is a device, generally driven by an electric motor, that puts an object, e.g., a rotor, in a rotational movement around a fixed axis.

Why is there a need for immediate centrifugation of blood samples?

Centrifuge Promptly It is important to separate the cellular and liquid portions of a blood specimen as soon as possible when the test requires a sample of serum or plasma. This is because the cells interact with the serum/plasma, altering its chemical composition and affecting test results.

Is G and RCF same?

Relative Centrifugal Force (RCF) or g-force (both are the same, RCF is expressed as units of gravity) is a measurement of the gravitational force that a sample is subject to. RCF is the preferred method of measurement as it will remain the same even if you are using a different centrifuge with a different rotor size.

How do we get plasma?

Plasma is produced when whole blood is collected in tubes that are treated with an anticoagulant. The blood does not clot in the plasma tube. The cells are removed by centrifugation. The supernatant, designated plasma is carefully removed from the cell pellet using a Pasteur pipette.

Can a microcentrifuge be used in a refrigerated setting?

Compact microcentrifuges isolate DNA or simply separate micro volume mixtures. Load microtubes and standard or dell-welled plates in the instruments easily. Adaptable to any industrial or laboratory setting, non-refrigerated or refrigerated models come with multiple mode options for the high-speed and powerful rotors.
