It is a machine that uses centrifugal force to rotate Vacutainers placed in slots specially prepared for this purpose. Blood specimens occasionally need to be tested by qualified medical personnel to identify ones` blood group, separate blood particles or check disease causing pathogens found in the blood.
One of the popular models is the 80-1 which rotates at speeds topping up at 4,000 rpm. There are many other models depending on the need.
How it works.
A centrifuge works by using the principle of sedimentation: as the rotor spins around a central axis, it generates a centrifugal force acting to move particles away from the axis of rotation, if the centrifugal force exceeds the buoyant forces of liquid media and the frictional force created by the particle, the particles will sediment.

How to use a centrifuge machine
- Insert the test tube sample into one of the portals.
- If needed based on the number of samples you are testing, insert test tubes filled with water for balance.
- Secure the lid and select desired settings.
- Start the centrifuge and wait for it to complete the cycle.
- When the centrifuge has stopped spinning, take out the balances and samples.
- Each sample will now be separated into its various components and ready for analysis.
Centrifuge models
Floor-standing models offer greater sample capacity and can achieve high speeds.
Bench-top models have a smaller footprint and general-purpose models are ideal for a wide range of applications. There are many bench-top models available including high-speed, micro centrifuge, clinical and cell washer models.
What to consider when purchasing a centrifuge:
- Sample volume
- Sample temperature
- Specific use
- Laboratory spaces/Centrifuge footprint
- Maximum g-force the centrifuge is capable to generate.
