What is a laboratory centrifuge?

The laboratory centrifuge is a tool that is primarily used in laboratories or in medicine, research and science.

Typical areas of application include:

  • food inspection and monitoring
  • quality assurance
  • the pharmaceutical industry
  • pharmacies
  • clinics and hospitals, for separating blood and sera
  • the metal processing industry, for the removal of metal separations
  • the aerospace industry, e.g. for the simulation of acceleration forces.

Certainly one of the most illustrative examples of a centrifuge is the classic salad spinner. The lettuce is made to rotate particularly quickly in a perforated drum so that it is pressed against its inner wall. The water flows out through the holes. In this way, the adhesion of the water to the respective solid is overcome. The laboratory centrifuge is also based on this simple but highly efficient function.

Components of substances or particles with a higher density are transferred outwards by the centrifugal force due to their higher physical inertia. In this way, they displace the segments with lower density, which in the course of this move to the centre of the container.

Compared to classical sedimentation, centrifugation is much faster and more efficient. By using the laboratory centrifuge, specific counter forces, such as thermal molecular motion, viscosity or adhesion, are overcome. The separation of the respective substances takes place on the basis of the respective density differences.

Laboratory centrifuge key figures and specifications

The performance and function portfolio of a centrifuge for the laboratory plays a significant role in terms of qualitative value. Accordingly, specific key figures are of great importance in this context. These include, for example:

The minimum and maximum speed

The rotational speed or the rotational frequency in the case of mechanical rotations indicates the number of individual rotations. This Gre is represented in revolutions per minute (min-1). Thus, the rotational speed denotes the reciprocal of the circulation time. The latter indicates how long it takes for one revolution to be completed.

In the field of centrifugation, the speed indicates the respective number of full revolutions per minute. In this process, laboratory centrifuges separate the solid substances from the liquid in a solid-liquid mixture due to the difference in density present.

The rotor type

Order the laboratory centrifuge with the appropriate rotor type in our excellently sorted store. Depending on the nature of the medium or substance as well as the type of container used, you can choose between the following rotor types at MedSolut.com:

  • Swing-out rot ors are ideally used for analytical and semi-preparative separations.
  • Fixed-angle rot ors are well suited for complete clarifications of pellets of macro-molecules as well as suspensions.
  • Vertical rot ors are best used for isopycnical separations.

The maximum G-value and the RCF-value

In addition to the speed of the centrifuge, the acceleration rate is also relevant. This is called the G-value, which determines the separation efficiency. The higher the speed of the centrifuge, the better the individual separation performance. The G-value is calculated from the speed and the radius or diameter of the bowl of your centrifuge.

The RCF value is the so-called relative centrifugal acceleration. It is often referred to as the G-value and is the characteristic value for centrifugation. It should be noted that the G-value can vary at the same speed of the rotors. Therelative centrifugal acceleration is therefore a multiple of the G-value.

The maximum radius (rmax)

The so-called maximum radius of the rotor (rmax) is specified by the manufacturer of the laboratory centrifuges. The rotation speed (rpm) indicates the revolutions of the centrifuge per minute.

The capacity

Depending on the amount of media to be separated, you should select the appropriate capacity of the centrifuge. If you have any questions in this regard, please do not hesitate to contact the friendly team of experts at MedSolut.com.

Centrifuge for the laboratory different types of centrifuges

No matter whether you need a universal centrifuge or a special model: For every need and every requirement, you will find the right centrifuge for the laboratory in our online catalogue. Discover the selection of high-quality laboratory centrifuges on MedSolut.com now. Choose your centrifuge for the laboratory directly from our portfolio:

Heated or cooled centrifuge

A heated centrifuge is recommended if you want to separate materials with different melting points quickly and gently at the same time. You will also find refrigerated centrifuges, for example for centrifuging blood, sera and other substances, in the MedSolut range. To prevent liquids from clotting or to protect them from bacteria and viruses, cooled or heated laboratory centrifuges are indispensable.

Small, micro and mini centrifuge

For the separation of small-volume samples, the high-quality small, micro and mini centrifuges are highly recommended. Whether you need a small centrifuge, a micro centrifuge or a mini centrifuge for your work, our friendly MedSolut specialists will be happy to explain it to you. We always have the right solution for you.

Stand centrifuge

With a floor-standing centrifuge you save valuable space on your laboratory and work bench. Benefit from many other advantages with the powerful models from the MedSolut portfolio.

Hmatocrit centrifuge

With an Hmatocrit centrifuge, the determination of red blood cell or erythrocyte volume fractions becomes even easier and more efficient. The powerful devices from the MedSolut.com store are also ideal for separating microblood and solutions.

Vortex centrifuge

The vortex centrifuge is the further development of the proven mini centrifuge. It combines several additional functions and is therefore ideally suited for the separation of micro substances and solutions.

Washing centrifuge

The washing centrifuge is mainly used in serology. It makes your daily laboratory routine much easier, especially if you work in transfusion facilities and clinics.
