A Comprehensive Introduction to Types of Centrifuges

Sep. 01, 2021

In the previous articles, we introduced the application and working principle of decanter centrifuges. Now HUADA introduces the classification of different centrifuges, in terms of usage, speed, separators, components, etc., in detail.

 

Pusher centrifuges

HR pusher centrifuge is a type of filtering centrifuge characterized by continuous feeding and intermittent discharging.Composed of hydraulic system, pushing mechanism, base, enclosure, transmission mechanism, basket, etc., this product is able to realize continuous feeding, separation, washing, discharging and other processes at full speed. This product is applicable to the filtration of sodium chloride, ammonium chloride, ammonium bicarbonate, urea, polyethylene, polypropyl ethylene, ammonium nitrate, oxalic acid, sodium sulfate, caffeine, etc. in the chemical, fertilizer, alkali production, salt production and other industries.

Benchtop centrifuge

A benchtop centrifuge is a compact centrifuge that is commonly used in clinical and research laboratories. It is driven by an electric motor in which the tube rotates around a fixed axis, generating a force perpendicular to the tube. Because they are so compact, they are suitable for small laboratories where space is at a premium.

 

Low-speed centrifuges

Low-speed centrifuges are conventional centrifuges that are commonly used in laboratories for routine separation of particles. These centrifuges run at a maximum speed of 4000-5000 rpm.
These are usually run at room temperature because they do not provide a system for controlling running speed or temperature. These are simple and compact centrifuges that are ideal for analyzing blood samples and other biological samples.
Low-speed centrifuges work on the same principle as all other centrifuges, but their application is limited to separating simpler solutions.

 

High-speed centrifuges

High-speed centrifuges, as the name implies, are centrifuges that can run at slightly higher speeds. High-speed centrifuges range from 15,000 to 30,000 rpm. High-speed centrifuges are typically used in more complex laboratories for biochemical applications and require high-speed operation. High-speed centrifuges come with different adapters to accommodate a variety of sample tube sizes and volumes. 

 

Horizontal peeler centrifuges

Peeler centrifuge is a new type of product that is developed on the basis of the ordinary peeler centrifuge. Based on the siphon principle, this product discharges the filtrate out via a siphoning device or skimming device. The filtering impetus can be changed by adjusting the liquid level at the suction inlet of the siphon pipe (skimming pipe) to further regulate the filtering rate, handling capacity, cake moisture and washing effect. A back-flushing device is configured to realize regeneration of the filter cloth and improve the separation effect. With back-flush, scouring, siphoning and other functions by configuring special devices, the filter cloth can be regenerated completely.

Gas centrifuges

Gas centrifuges are centrifuges explicitly used to separate gases based on inherited isotopes. The centrifuges are based on the same centrifugal force principle as all other centrifuges, in which molecules are separated according to their mass.
These centrifuges are arranged in series, separating the gas into two units based on isotopes, which then go to the next centrifuge for further processing. Gas centrifuges have replaced other gas diffusion methods because they provide higher gas yields in higher concentrations than previous technologies.

 

Hematocrit centrifuges

Hematocrit centrifuges are specialized centrifuges used to determine the volume fraction of red blood cells (RBCs) in a given blood sample.
The hematocrit values provided by the centrifuge can be used for biochemistry, immunology, blood testing and other general clinical tests. For example, it can be used to help diagnose blood loss, erythrocytosis, leukemia and multiple myeloma.
The components of a hematocrit centrifuge are similar to those of a benchtop centrifuge, but this centrifuge is specifically designed for use with blood samples.

 

Vacuum centrifuges

Vacuum centrifuges use centrifugal force, vacuum and heat to accelerate the laboratory evaporation of samples. This type of centrifuge is used in chemical and biological laboratories to efficiently evaporate the solvents present in the sample and thus concentrate it. Centrifuges work by lowering the chamber pressure, which also lowers the boiling point of the sample. This leads to evaporation of the solvent and concentration of the particles to be separated.
