What is a Centrifuge?

Centrifuges separate or concentrate substances suspended in a liquid medium by density. Space-saving fixed- and variable-speed benchtop or tabletop centrifuges are used for applications including tissue culture, protein work, DNA/RNA research, and cell harvesting.

Although spinning is used to achieve separation in all centrifuges, the rotor’s rpm only indicates the power of the motor. The best indication of separation power is its RCF, or relative centrifugal force. Versatile multipurpose centrifuges are the most common type, with an RCF up to about 24,000 × g, a variety of volume ranges, and the ability to spin plates.

They can accommodate different types of rotors, including fixed angle, swinging bucket, and continuous flow. Ultraspeed centrifuges offer g-forces up to 1,000,000 × g, useful in nanotechnology.

Microcentrifuges spin small sample volumes, such as 0.2-mL PCR tubes, at very high speeds. Other factors to consider include noise level, easy bowl access, refrigeration capabilities, and rotor material, which can be metal, plastic, or composite.

Things to Note When Choosing the Best Benchtop Centrifuge

With a number of choices available in the market, it is necessary to know how to select the most appropriate and best type of centrifuge.  Remember three significant factors while choosing a centrifuge.

  • Requirements
  • Specifications
  • Total cost

Requirements

Requirements

It is essential to know your requirements before purchasing a centrifuge since there is a suitable and appropriate type of centrifuge available for each application. The most widely recognized applications that use centrifuge devices are medical and research laboratory tasks.

The most commonly utilized centrifuges in these fields are micro-centrifuges, benchtop centrifuges, high-speed centrifuges, ultracentrifuge, and hematocrit centrifuges. For instance, ultracentrifuges are generally utilized to extract cellular components, for example, DNA, in the fields of molecular biology, biochemistry, and microbiology.

Hematocrit centrifuge models, alternatively, are frequently utilized to divide blood components into the plasma and RBC layer.

Specifications

A few of the specifications that you ought to consider are:

  • Speed and performance (cycles/minute and relative centrifugal force)
  • The capacity of the device
  • Easy to operate
  • Reliability

The rate of centrifugation, generally known as revolutions per minute (RPM), is a term utilized by the developers to tell how quickly the centrifuge will rotate despite the size of the rotor. In contrast, the relative centrifugal force (RCF) is the force produced by the revolutions of the rotor and applied to the contents of the rotor which results in separation of fluids in the centrifuge.

The RPM and RCF forces are among the most important specifications to consider while selecting centrifuges because the requirement for the centrifugal force varies for the sedimentation of a different specimen. For instance, to accurately isolate specific bacterial cells from a specimen, high-speed or ultracentrifugation is required.

A few centrifuges have fixed speed, whereas other centrifuges have variable speed settings because of control panels or rotating frameworks that allow the user to choose a particular speed or power.

This variable-speed option and rotary selection enable the users to utilize their device for a wide range of applications (multipurpose centrifuge).

The capacity of the device is determined by the maximum quantity or volume of samples that you can accommodate inside the rotor. Benchtop centrifuges, ultracentrifuges, or multipurpose centrifuges, can fit up to 1000 ml of sample per tube or bottle, based upon the model.

In addition, a few centrifuges are assembled with refrigeration systems, which are helpful for temperature labile specimen.

Total Cost

It is important to keep in mind that a centrifuge with higher power will require a higher amount of energy to operate. Consequently, it is less energy-efficient as compared to the low-speed centrifuges.

However, a few models are less expensive and could still deliver acceptable outcomes, although not as precise as expensive high-speed centrifuges.

Another significant point to consider while choosing a centrifuge is that the device can be purchased with or without rotors; you need to purchase the rotors separately if the rotors are excluded from the model.

In addition, the warranty of the device ought to be taken into consideration in case there is an unexpected turn of events that you did not anticipate.
