Buying A Laboratory Centrifuge

A laboratory centrifuge is a piece of equipment which spins liquid samples at high speeds with the help of a motor. There is a very wide variety of lab centrifuge for sale today. This can be attributed to the speed at which advancements in medicine and technology are made. As such, it can be daunting task for medical institutions to zero in on the appropriate product.

However, there are certain criteria that they can use especially when deciding to buy centrifuge. The major one is the protocols and applications the lab centrifuge will be needed for. These include the formats the equipment supports such as disposable tubes, centrifuge tube, centrifuge bottles, microplate centrifuge tubes or blood collection tubes. The relative centrifugal force (RCF) required, centrifuge price and sample volume needed are also important factors to consider.

Depending on the schedule of activities in the laboratory, number of people using the product and range of protocols, the number of samples that can be processed at a go should be determined. Different centrifuge tubes come with separate types of rotors such as swinging bucket and fixed angle rotors.

Additionally, the space available in the laboratory will determine if a bench top or floor based centrifuge should be purchased. The final determining factor is of course the centrifuge cost. Herein are several types of laboratory centrifuges depending on the needs and requirements of a clinic or hospital.

General Purpose Benchtop Centrifuges

lab centrifuge for saleGeneral purpose bench top centrifuges are the most common machines found in laboratories. They are very versatile and often highly practical. These products provide a wide range of speeds, volumes and rotor types within a single piece of equipment. This means that they can be easily tuned to suit the protocols of any laboratory.

General purpose bench top centrifuges offer relative centrifugal forces of up to 24,000 x g. Their volumes range from 0.2 ml to 750 ml and they can be equipped with an array of swinging bucket and fixed angle rotors. They are preferred because they are fit for multiple users when there is a limitation of space or time in a laboratory.

These bench top centrifuges have a wide range of uses including protein research, sub cellular separations, cell harvesting, DNA or RNA separation and culturing of tissues.

where to buy centrifugeHigh Speed Floor Based Centrifuges

These are very powerful, versatile and high capacity centrifuges. They are ideal for laboratories with multiple users, wide range of protocols and applications offering a choice of up to 40 rotors. Most high speed floor based centrifuges have a relative centrifugal force of up to 70,450 x g and volume ranges from 1.5 ml to 1000ml.

Their main advantage is there is no need for laboratories to get specialized centrifuges for different applications. They are advisable choices for institutions that perform general applications such as sub cellular separations, DNA/RNA separations, protein precipitation, tissue culturing and whole cell separations.

High Speed Bench Top Centrifuges

These are also very powerful and provide g forces almost similar to those of their floor based counterparts. The main difference between them is that bench top high speed centrifuge has a limited set of rotors. Their more common applications and rotors include three types.

A high speed fixed angle rotor with low volumes of between 1.5 ml – 2.0 ml. These are recommended for DNA/RNA research applications. There is also a high speed fixed angle rotor with middle range volumes from 5.0 ml – 15 ml. They are commonly used for sub cellular pelleting steps. Finally they have lower speeds swinging bucket rotors with high volumes of up to 200 ml that are used mainly for whole cell harvesting.

As such, the average relative centrifugal force provided by high speed bench top centrifuges is about 50,000 x g with a volume range of 1.5 ml to 200 ml. They offer a significant range of swinging bucket and fixed angle rotors.

Clinical Centrifuges

This medical centrifuge is a compact machine that is specially designed for clinics or hospitals that need low throughput units to rotate tubes at very low speeds to enable medical examination. However, clinical centrifuge is mostly used for spinning urine samples and blood collection tubes for diagnosis. Moreover, this machine is often portable centrifuge.

Most clinical bench top centrifuges have a relative centrifugal force that peaks at or below 3000 x g. They support a volume range of 3 ml to 15 ml. Also, their throughput ranges from 4 to 28 tubes per run. The number depends on the unit selected and the size of the tubes.


Microcentrifuges are incredibly necessary machines in all laboratories. These compact units provide relative centrifugal forces of up to 21,000 x g. The rotors they are equipped with support for the commonly utilized 0.2 ml plate centrifuge rotor tubes and the 1.5 ml or 2.0 ml disposable microcentrifuge (microfuge) tubes and filters.

These centrifuge tubes are caped, semi-conical and are manufactured from a flexible plastic that resembles polythene. Microcentrifuges are used for applications that require micro volumes such as mini preparation kits, plasmid research and DNA or RNA separation. They are one of the more portable products.

Industrial Centrifuges

Industrial centrifuges are machines that are used to separate fluids or particles. They are broadly classified as either sedimentation or filtering centrifuges. Sedimentation centrifuges use centrifugal force to separate solids from liquid or liquids from other liquids. Filtering centrifuges use centrifugal force to pass a liquid through a filtration medium.

Industrial centrifuges are used in several fields. They are employed in pharmaceutical laboratories to produce drugs and vaccines. Chemical processing plants use them to produce raw materials such as salts and plastics. Additionally, the production of bio diesel, synthetic fuels and ethanol depends on industrial centrifuges.

Refrigerated Centrifuges

Refrigerated centrifuges are ideal for use with samples that are sensitive to temperature. They are highly versatile and are available in table top centrifuge or floor based designs. They are unique in that they have temperature programming features with most possessing a digital temperature controller.

Additionally, they can be high, moderate or low speed depending on the lab protocols. Refrigerated centrifuges are mostly used in bio technology and pharmaceutical laboratories. The type of blood centrifuge that is mostly used in blood banks is the refrigerated microcentrifuge.

It is important to note that laboratory centrifuges are not mass produced; therefore the centrifuge machine price will be higher than other processing laboratory equipment. The cost of centrifuge will vary depending on the centrifuge manufacturers. However, it is a worthwhile investment to buy a new one as used centrifuge break down easily due to the high speeds involved.
