Centrifuges

A centrifuge is a device that applies a sustained centrifugal force (that is, a force produced by rotation) to propel matter out of the center of rotation. This principle is used to separate particles in a liquid medium by sedimentation. In general, the centrifuge is used in laboratories as a process for separating the sedimentation of liquid and solid components.

What are the types of centrifuges?

There are different types of centrifuges, such as low speed centrifuges, micro hematocrit centrifuges, and ultracentrifuges, the latter type is generally used for the separation of proteins. But each of them has different speeds:

  •   Centrifugal macro ranging from 2,000 to 6,000 R.P.M.
  • Micro centrifuges between 10,000 and 18,000 R.P.M
  • Ultracentrifuges ranging from 20,000 to 75,000 R.P.M.

Depending on the type of centrifuge, each one will have different operation and characteristics (type of rotor and type of sample holder tube). In the case of its electrical control, it will always have different elements such as time control, temperature control, refrigeration control, rotation speed, among others.

 
 

Types of Centrifuges to work correctly in a laboratory

 
 

Non-Refrigerated Centrifuge

The centrifugation process has a wide range of uses in all fields of our lives, especially in the medical field. Centrifugation devices have different uses. For example, blood separation, DNA / RNA separation, cell culture separation and others such as the study of viruses, proteins, nucleic acids and polymers. These types of high-end centrifuges can separate mixtures of different size molecules or microscopic particles, such as blood cells. This technique has become a fundamental step in the analysis of blood samples, especially in blood bank laboratories.

This is one of the newest techniques in the medical field to hold donated blood and "wash" it. To do this, you need this blood washing centrifuge, the high-end device your laboratory needs. The red blood cell flushing procedure is done when people need a blood transfusion. In this process, most of the plasma, platelets, and white blood cells are removed. These types of tests are also performed to see if the donor's blood is compatible with the recipient's blood or not. That is why this device has become an essential and fundamental device in any blood bank laboratory.

 
 

Refrigerated Centrifuges

One of the most important processes in any type of laboratory is the separation of particles. That is why centrifuges are useful to perform this important procedure in order to achieve the desired results. Is there another device that can perform this task? We hardly believe it. Centrifuges are the devices you must have if you need to perform a fast turning force to separate the contents of the mix with different densities. High capacity refrigerated centrifugal devices have different uses in any medical, scientific or medical field. For example, blood separation, DNA / RNA separation, cell culture separation and others such as the study of viruses, proteins, nucleic acids and polymers. Its main function is to collect rapidly sedimenting substances such as erythrocytes, yeast cells, nuclei, and chloroplast.

One of the uses for this high capacity refrigerated centrifuge is to collect rapidly sedimenting substances such as erythrocytes, yeast cells, nuclei, and chloroplast.

 
 
 
 
 
 

Our best-selling Centrifuge

Microhematocrit Centrifuge Model YR134-2

Microhematocrit is a very useful procedure to determine the ratio of the volume of packed red blood cells to the volume of whole blood by centrifuging a quantity of blood. Microhematocrit centrifuges are very common when trying to diagnose blood loss, polycythemia (an elevation of the red blood cell count to previous normal levels), anemia, bone marrow failure, leukemia, and multiple myeloma. The microhematocrit centrifuge can quickly reach a speed of 11000 rpm or more.

The parts and uses of the microhematocrit centrifuge, this RCF MAX RCF Tabletop Centrifuge low speed is 13500g and its maximum speed is 12000rpm. About the control system, this YR134-2Model is powered by microcomputer control, DC brushless motor, with stable operation function, minimal noise and high-speed precision. This means that this model meets environmental standards. Another great feature is that this is a programmable machine, so operation data can be stored automatically.
