Laboratory centrifuges

The centrifuge is a laboratory equipment that generates rotational movements, it has the objective of separating the components that constitute a substance.

Today there is a diversity of centrifuges that have different objectives, regardless of the type of research or industry. Depending on the type of centrifuge, each one will have different functions and characteristics (rotor type and sample holder tube type).

The two main types of rotors used in laboratory centrifuges are horizontal (also called swing bucket) and fixed angle (or angle head).

Horizontal rotors are so named because the buckets or racks that support the centrifuge tubes are suspended in a way that allows them to tilt upwards in the horizontal plane when subjected to the influence of a centrifugal field.

Therefore, when operating the centrifuge, the particles settle along an unobstructed radial path, away from the center of rotation.

What is a high speed centrifuge?

High-speed centrifugation is an irreplaceable tool for the isolation and characterization of multiple biological structures: from biomolecules, such as nucleic acids and proteins, to cell organelles and viruses.

A centrifuge is a machine that spins a sample at high speed, in order to generate a force –called centrifugal force– that separates the components of said sample, in order to analyze them. It is applicable to biology, pharmaceuticals, chemistry, among others.

It is an extremely useful piece of equipment for many types of clinical and research trials.

Different types of centrifuges accommodate different types of centrifugation: preparative centrifugation, which aims to isolate specific particles, and analytical centrifugation, with which physical properties such as sedimentation rate or molecular weight can be estimated.

Centrifuge: Rotor Types

What is the difference between these types of centrifuge rotors?

Horizontal rotors are so named because the buckets or racks that support the centrifuge tubes are suspended in a way that allows them to tilt upwards in the horizontal plane when subjected to the influence of a centrifugal

Fixed angle rotors hold the tubes at an angle to the axis of rotation. The angle varies with different rotors, being common between 25° and 40°. Although the particles settle along a radial path in these rotors as well

Types of Centrifuges:

Refrigerated Centrifuges

The 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 the centrifuge. It is mostly made of titanium alloy or aluminum alloy.

Non-Refrigerated Centrifuges

YR0139 low speed benchtop centrifuge is newly developed by our company based on extensive experience in the centrifuge line. It can meet the requirements of clinical medicine.Definition of low speed centrifuge: Centrifuges with a speed below a certain level
