Benchtop Centrifuge Machines

According to Wikipedia, “A centrifuge is a device that uses centrifugal force to separate various components of a fluid.” They were first used in the late 1800s to separate cream from milk, and have been used in laboratories ever since.

Centrifuge machines are the most common items of equipment found in a laboratory and are used in research, clinical, biochemistry, and molecular biology labs.

There are two main types of centrifuge machines: floor standing and benchtop. Floor-standing units can be full-height models or small enough to be able to fit under a workbench. Benchtop models, as the name implies, have a small footprint and several models can be placed on a trolley allowing you to relocate them to another location.

Benchtop units are the most popular type of centrifuge found in the workplace due to their relatively low cost and the fact that they are small enough to fit on most workbenches. The larger, floor-standing units, may be cost-prohibitive unless you have a large budget.

So, let’s examine what you should look for when you’re in the market for a centrifuge, in particular, a benchtop model.

G-force—maximum RCF (Relative centrifugal force)and RPM (Revolutions per minute).
This is one of the factors you should consider carefully when choosing a centrifuge. The G-force (RCF) should not be confused with RPM.
Capacity and size—the number of tubes and their size.
Depending on your requirements, you should make sure the unit can cater to the number of tubes you need and what size of tubes it can handle.
Refrigeration options (or not).
Do you require samples to be refrigerated or not? Bear in mind that refrigerated centrifuges are considerably more expensive.
Warranty/after-sales service. Look closely at the unit’s warranty. Do they offer a one-year or two-year warranty? Perhaps even longer if the model is particularly expensive. What after-sales service do they have?

In addition, one more vital factor in choosing a centrifuge is what kind of safety features does it have? A few to watch for are:
An electronic lid lock. This will prevent the lid from being opened while the machine is running.
A balance sensor. This will sense if the centrifuge has been loaded correctly and is in balance and will stop the machine if it senses a high degree of vibration.
Rotor seals. This will prevent any leakage of any bio-hazard material while the centrifuge is running.

Here are our suggestions for the best benchtop centrifuge machines (We wanted to thank the community our community of Metallurgists from around the world that supported us in producing this list):

You can place up to six 20ml tubes in the centrifuge, but to ensure the machine runs smoothly, there must be an even number of tubes placed symmetrically in the machine. If you have only one sample, then it is recommended that you add a tube of clean water in the opposite slot to balance the machine.

It must be noted that the application guide that accompanies the unit has obviously been translated into English and as such, users may have difficulty understanding the instructions given. However, if you read them a few times, then the intended meaning will become clear albeit somewhat disjointed.

In conclusion.

If you are looking to buy a benchtop centrifuge for your lab, school, or workplace, then choose a model that will fit your requirements in size, tube capacity, and mL. Other important factors you need to bear in mind include:
• RPM and RCF.
Do you need the centrifuge to spin fast? A centrifuge may have a high RPM (revolutions per minute), but a low RCF (relative centrifugal force), so look at both numbers in the specifications.
• Temperature selection.
Do you need heating or cooling facilities in a centrifuge? Most models are designed to operate at room temperature. There are, however, some refrigeration models that can run at -10°C or -20°C.
• Safety features.
What safety features does the unit have? Does the lid or cover lock when the unit is in motion? Is there a balance sensor that stops the machine if it is out of balance? Is the rotor sealed to prevent leakage during the process?
• Warranty.
Buying a centrifuge can be a large investment, so look at the warranty given by the manufacturer. Some offer a one-year warranty, while a few offer a five-year warranty.

Choose a centrifuge model that has the most options, has built-in safety features, is the size you need for the workplace, and is within your budget.
