Laboratory Centrifuges

The centrifuge is an essential laboratory equipment that generates rotation movements in order to separate the components that constitute a solution. This equipment applies a sustained centrifugal force (that is, a force produced by rotation) to push the matter out of the center of rotation. 

Centrifugation is a technique governed by Stokes law, which proposes that particles settle more easily as long as they are larger in diameter and specific weight, and when their viscosity is lower. Centrifugation is used to isolate or concentrate suspended particles in a liquid taking advantage of the different speed of displacement according to its shape, size or weight when subjected to a centrifugal force. Centrifugal force is the force exerted on a body when it rotates around an axis.


Types of Centrifuges a Laboratory may need

Non-refrigerated Centrifuges

At Kalstein we are specialists in the manufacture of laboratory equipment, and our clinical centrifuges usually have a wide variety of advantages, such as:

  • Ease of operation and the best technology.
  • Accident safety device.
  • Guarantee of separation of the components of a mixture.
  • They have legs covered with non-slip material to fix on tables or inns.
  • Ease of cleaning, maintenance and safety.
  • They have a rotor that avoids loud noises and vibrations.
  • Models that provide economy, efficiency and durability.

Refrigerated centrifuges

It is a equipment used in the processes of the separation of the sedimentation of the liquid and solid components of a sample, this apparatus generates rotation movements and through the centrifugal force accelerates the decantation or sedimentation of the components of the sample, according to their density, there are different types of centrifuges, which pursue the same objectives.

In laboratories centrifuges produce a high speed rotation, separating layers of the different materials that make up the sample and that generates the densest elements of the sample to be deposited in the bottom of the container and the lightest ones to be kept in the top of it; the relative force of centrifugation is measured in multiples of gravity, and by its physical size cannot be represented in units.


In Kalstein you can find the ideal Centrifuges for your Laboratory

For each research or analysis there is a special type of centrifuge, and the type of centrifuge is determined by the value of the relative centrifugal force (F.C.R.), this is the force needed for particles to be separated. Depending on the speed range, there are several types of centrifuges.

Refrigerated high-speed centrifuge table YR0125

The main operating principle of the high-speed centrifuge: high-speed centrifuge is the powerful centrifugal force generated by the high-speed rotation of the frozen centrifuge rotor of the high-speed centrifuge to accelerate the sedimentation rate of the particles in the liquid and separate the sedimentation coefficient and flotation density from the sample.

Centrifuge is a type of machine that performs solid-liquid, liquid-liquid or solid-liquid phase separation under the action of centrifugal force. The rotor is the main component of centrifuge. It is mostly made of titanium alloy or aluminum alloy. It is installed at high speed. The separation is achieved by centrifugal force on the vertical or horizontal axis, and can be used for centrifugal separation separation separation, centrifugal filtration and centrifugal sedimentation. The separation factor is the main indicator of centrifugal separation performance. It is the relationship between centrifugal force and material gravity, which is equal to the ratio of centrifugal acceleration to gravity acceleration.

Process of using Centrifuges

These medical equipment thanks to its function are not only necessary and used in laboratories, but also in clinics, public health centers, among others where the separation of solutes from their solvents is required, at the time of cleaning and maintenance we must recognize the parts and accessories of the centrifuges to establish a maintenance routine, according to the type of centrifuge, among the variety of these machines we have: low-speed serum or plasma separation centrifuges, centrifuges for microhematocrits and ultracentryfuges for protein separation.
