Blood Sample Centrifuge Machine
Description
Technical Parameters
A blood sample centrifuge machine is a key device used in medical laboratories to separate blood components, separating different components of blood (such as red blood cells, white blood cells, platelets, and plasma) by centrifugal force to provide basic samples for clinical diagnosis, blood testing, and biological research. It works on the principle of centrifugal force. When the blood sample is placed in the rotor of the centrifuge and rotated at high speed, the blood components of different densities are stratified under the action of centrifugal force:
The red blood cells settled to the bottom of the centrifuge tube because of their high density.
White blood cells and platelets form an intermediate layer (the "leukocyte layer" or "buffer layer");
The plasma is in the upper layer.
Blood sample centrifuges are indispensable tools in medical laboratories, and their efficient and precise separation capabilities provide important support for clinical diagnosis and scientific research. With the advancement of technology, the improvement of centrifuge automation and intelligence will further optimize the experimental process and improve the quality of detection.

Application in the extraction of biological macromolecules
In the field of biomedical research, blood sample centrifuge machines are the core tools for separating and extracting biological macromolecules such as DNA, RNA, proteins, etc. It generates centrifugal force through high-speed rotation to layer substances of different densities and sizes, thus achieving efficient separation of target molecules. The following is a detailed description of its application from the principle, operation process, application scenario and optimization strategy.
The working principle of centrifuge and the separation mechanism of biological macromolecules
Centrifuges operate on the principle of density gradient separation: when a blood sample is rotated at high speed, biomacromolecules of different densities are assigned to different positions due to differences in centrifugal force. For example, cell fragments and nucleoproteins are deposited at the bottom of the tube because of their high density, while proteins and nucleic acids in plasma are distributed in layers. By adjusting the rotational speed (RPM) and centrifugal time, the separation effect can be precisely controlled.
The operation process of biological macromolecule extraction
Sample pretreatment
Anticoagulant treatment: Blood samples should be added with EDTA, heparin and other anticoagulants to prevent coagulation from affecting the separation.
Cell lysis: Destruction of cell membranes by the addition of lysates (such as Trizol reagents), releasing nucleic acids and proteins.
Centrifugal parameter setting
Low speed centrifugation: 3000-5000 rpm for 5-10 minutes to remove cell debris and unlysed cells.
High speed centrifugation: 1000-16000 rpm, 10-20 minutes, separation of nucleic acids or proteins in the supernatant.
Ultracentrifugation: >100,000 rpm, used to separate suborganelles or viral particles.
Target molecule extraction
Nucleic acid extraction: Take the supernatant, add organic solvent such as chloroform, and separate the aqueous phase (including nucleic acid) and organic phase by centrifugation.
Protein extraction: The supernatant is taken and the protein is separated using a precipitant (such as trichloroacetic acid) or a ultrafiltration membrane.
