Adding microtubes 2 at a time will ensure that you're adding an even amount of weight to either side of the centrifuge.
By adding 1 equally weighted tube on either side of the centrifuge, you'll keep the center of gravity exactly in the middle of the centrifuge rotor..
A centrifuge works by rotating at rapid speeds, thereby separating substances using the power of centripetal force (and the apparent centrifugal “force” — more on that concept later).
The force applied can reach several hundred or several thousand times that of the earth's gravity..
Centrifuges separate or concentrate substances suspended in a liquid medium by density.
Space-saving fixed- and variable-speed benchtop or tabletop centrifuges are used for applications including tissue culture, protein work, DNA/RNA research, and cell harvesting..
Benchtop centrifuges are the equipment utilized in laboratories to separate and purify molecular mixtures in a liquid medium based on their density gradient..
Centrifuge speed
Centrifuges may be classified based on maximum speeds, measured as revolutions per minute (RPM).
Speeds range from 0-7,500 RPM for low-speed centrifuges, all the way to 20,000 RPM or higher..
Benchtop centrifuges work on the sedimentation principle, i.e., substances separate according to their density under the influence of Earth's gravitational force 'g' (g = 9.81ms-2).
The sedimentation rate increases when these samples undergo acceleration in a centrifugal field (G \x26gt; 9.81ms-2)..
A High Speed Centrifuge is a device that uses centrifugal force to separate particles of different mass or densities suspended in a liquid.
Rotating the solution in the tube at high speeds gives the angular momentum of each particle a centrifugal force proportional to its mass..
Price Range: Rs. 65000 - 650000 Per Unit..
The choice of centrifugation speed depends on the size and fragility of the particles in the sample.
The smaller the particle size, the higher the centrifugation speed.
For example, bacterial cells are pelleted at higher speeds (2000–10,000 x g) than mammalian cells (500–2000 x g)..
Centrifuges separate or concentrate substances suspended in a liquid medium by density.
Space-saving fixed- and variable-speed benchtop or tabletop centrifuges are used for applications including tissue culture, protein work, DNA/RNA research, and cell harvesting..
In 1864, Antonin Prandtl invented the first centrifuge-type machine, which was used in the dairy industry to separate milk and cream on a large scale.
Following Prandtl, Friedrich Miescher, a Swiss physician and biologist, was the first to apply centrifugation in the lab..
Centrifugation is used to collect cells, to precipitate DNA, to purify virus particles, and to distinguish subtle differences in the conformation of molecules.
Most laboratories undertaking active research will have more than one type of centrifuge, each capable of using a variety of rotors..
Fisherbrand™ Portable Centrifuge Kit offers a convenient way to spin down and prepare samples outside of a conventional laboratory environment Compact, economical high-speed microcentrifuges, ideal for nucleic acid research and other microliter volume separations.

The working principle of the clinical centrifuge is mainly divided into two parts:
A centrifuge that offers consistent temperatures is sometimes necessary when working with liquid substances susceptible to heat degeneration.
An excellent choice of medical equipment for this purpose is a refrigerated microcentrifuge, which can spin samples of up to 2 ml.
