What Is a Desktop Centrifuge?
A centrifuge is a device that uses centrifugal force to separate samples according to the specific gravity of their particles.
A desktop centrifuge is available in two types: the swing type, which rotates at several thousand rpm, and the angle type, which is capable of high-speed centrifugation at several tens of thousands of rpm.
There are several types of rotors, including those for test tubes, microplates, and microtubes, depending on the type and size of container.
High-speed rotation raises the temperature of the rotor, which may damage the specimen. In such cases, a cooling centrifuge equipped with a cooling function is used.
There are also products that can perform centrifugal separation while heating.
Uses of Desktop Centrifuges
Centrifuges are used in a variety of industries, but desktop centrifuges are most often used for scientific experiments.
- Cell culture
- Blood (separation of blood cells, serum, plasma, etc.)
- Biochemistry (e.g. DNA, RNA extraction)
- Analytical (liquid-liquid extraction, etc.)
It is used in a wide range of experiments due to the difference in rotation speed.
There are also simple desktop centrifuges that are used without a rotation speed setting.
This is a product that can be easily used to spin down samples in microtubes, octuplets, and the like.
It is also used for medical purposes. If plasma or serum needs to be separated promptly after blood collection, desktop centrifuges, which takes up relatively little space, can be conveniently installed at a medical site.
Principle of Desktop Centrifuges
Each substance has its own specific gravity. Centrifugal force is used to separate them according to the difference in specific gravity.
For example, when the difference in specific gravity is small, the centrifugal time is lengthened or g is increased. Therefore, when performing centrifugal separation, it is necessary to select a model that can handle the purpose.
For cell culture and blood cell separation, most can be separated by low-speed centrifugation at about 3000 rpm.
In the case of DNA or RNA extraction, centrifugal force of several tens of thousands rpm is required, so a high-speed centrifuge is used.
Incidentally, rpm (round per minute) refers to rotational speed, while g (gravity) refers to centrifugal force (relative centrifugal acceleration).
At the time of use, g and rpm can be converted using a conversion table provided by each manufacturer.
High-speed rotation of a sample with unbalanced weight may cause vibration and risk breaking the centrifuge. Before centrifuging, the sample must be balanced, the vessel must be undamaged, and the water in the device must be dried after use under cooling.
Care must also be taken with the material of the vessel used for centrifugation.
Before centrifuging, it is also necessary to confirm that the strength of the material of the container to be used can withstand centrifugal force.
