A Centrifuge Machine

A centrifuge is a system that separates the components of a liquid or fluid (and even gases) using the centrifugal force. It is a biological instrument used for the separation of liquid material based on its density and weight. This is done by rotating the fluid in a container at high speed.

Centrifuges are mainly used in laboratories to prepare test samples for analysis. For example, a centrifuge may be used to separate plasma from the blood. This machine is equipped with a rotor in which the samples to be prepared are placed.

To explain it better, it is like getting butter from the buttermilk.

There are different types of centrifuges with one or more applications linked to them. So one must look into the exact requirement while choosing a centrifuge

The different types of centrifuges-

1. Standard centrifuges: 

These are models and that can be used for urine analysis, stool analysis, etc. They have a rotational speed of between 5,000 and 15,000 rpm.

2. Micro centrifuges:

These are generally used for small sample quantities, such as capillary tubes for example. They are mainly used for blood sample work. Their rotational speed is greater than 10,000 rpm. These centrifuges machines have a compact design.

3. Ultra centrifuges: 

These types are very high-speed centrifuges. They are majorly used for advanced analyses in specialized laboratories or research organizations. Their rotational speed is quite high ranging between 50,000 and 100,000 rpm.

4. Manual centrifuges

They are operated manually by a person using a crank, having a rotational speed of around 3,000 rpm.

There are a variety of rotors that are installed in the centrifuge machines such as High capacity swinging bucket rotor, High-performance fixed-angle rotor, etc. They are used in separation and extraction.

The centrifuge may have the following functions:

Hematology: These include Hematocrit Centrifuges which effectively determines blood’s erythrocyte volume fraction. They can often manage 24 capillaries at the same time and their maximum rotational speed is usually 12,000 rpm.

Molecular biology: Herein centrifuges are used for DNA extraction for example. In this category, we may also require a refrigerated centrifuge. Refrigerated centrifuges are used to process samples that need to be kept at a constant/similar temperature. It is therefore essential that they operate at high speeds while maintaining the same temperature. In most cases, the temperature range offered by these centrifuges is between -20 and -40 degrees Celsius, which makes them appropriate for DNA or RNA analysis

 Bacteriology: Here centrifuges are used for the cytology of liquids from different sources, for example, Parasitology centrifuges may help in performing parasite concentration tests.

Key Considerations while buying a Centrifuge

Here are some of the most important points to be kept in mind when purchasing a centrifuge.

1. The G-Force

One of the most important things to consider while choosing a centrifuge is G-Force. It is a critical factor that determines the applications that your centrifuge will handle. 

2. Maintenance Reliability

Centrifuge equipment maintenance is critical if you wish to have an extended lifespan. You could go in for yearly maintenance. This would include checking the temperature, brushes, and speeds.

3. Replacement Parts Availability

One needs to be sure that the replacement parts are easily available even after purchase. It would be unwise to buy a device whose spare parts are not available! 

4. The Size & Capacity of the Centrifuge

The wide variety of centrifuges in the market features a different capacity or size. One must review the equipment’s capacity as it determines the applications that it can handle and it suits your requirement. The capacity determines the total number of sample tubes that can be placed in a centrifuge each time. Since different centrifuges can handle different sample sizes.

Hence, Moglix comes up with a wide variety of Centrifuge machines with a long-lasting time-span and will provide you with accurate results.
