Key Differences
A centrifuge is a device that uses rotational force to separate components of a mixture based on their density. On the other hand, a spindown refers specifically to using a centrifuge at high speeds for a short duration to quickly sediment particles, typically for preparatory steps in laboratory protocols.
Centrifuges are versatile and used in various settings, including medical labs, research institutions, and industrial applications, facilitating a wide range of separation tasks. Whereas spindowns are generally limited to laboratory settings, where rapid sedimentation of cells, precipitates, or particulate matter is required.
The operation of a centrifuge can be adjusted in terms of speed and time to suit different separation needs, ranging from gentle separation of delicate cells to the robust separation of heavier particles. On the other hand, spindowns typically operate at high speeds for brief periods to achieve quick results, often sacrificing some precision for speed.
In terms of equipment, centrifuges come in various sizes and specifications, from small benchtop units to large floor models with advanced features like temperature control. In contrast, a spindown usually utilizes smaller, more specific centrifuges designed for quick operations, such as microcentrifuges.
While the principle of centrifugation underlies both centrifuges and spindowns, the latter is essentially a subset of centrifugal applications, focusing specifically on rapid process applications necessary in certain experimental or clinical protocols.

We avoided using spindown for delicate cell types to prevent damage.
Centrifuge
An apparatus rotating at high speed to achieve separation of mixed substances.
We placed our samples in the centrifuge to clarify the suspension.
Spindown
A rapid centrifugation technique to sediment larger particles in a mixture.
For the PCR setup, we performed a quick spindown of the samples.
Centrifuge
A tool in industrial applications to separate out components such as in wastewater treatment.
The factory utilizes a large centrifuge to extract solids from liquids.
Spindown
A specific use of centrifuges focusing on speed rather than separation accuracy.

Centrifuge
A device in clinical settings for processing blood and other bodily fluids.
The centrifuge hummed quietly as it spun the vials.
Spindown
Often used in laboratory protocols to prepare samples for further analysis.
After adding the reagent, a brief spindown was necessary.
Centrifuge
A centrifuge is a device that uses centrifugal force to separate various components of a fluid. This is achieved by spinning the fluid at high speed within a container, thereby separating fluids of different densities (e.g.
Spindown
A reduction in spin speed (of a hard disk, pulsar etc)
Centrifuge
An apparatus consisting essentially of a compartment spun about a central axis to separate contained materials of different specific gravities, or to separate colloidal particles suspended in a liquid.
Centrifuge
An apparatus in which humans or animals are enclosed and which is revolved to simulate the effects of acceleration in a spacecraft.
Centrifuge
To rotate (something) in a centrifuge or to separate, dehydrate, or test by means of this apparatus.
Centrifuge
A device in which a mixture of denser and lighter materials (normally dispersed in a liquid) is separated by being spun about a central axis at high speed.
Centrifuge
(figuratively) An apparatus in which humans are spun to simulate acceleration in an aircraft or spacecraft.
Centrifuge
To rotate something in a centrifuge, typically in order to separate its constituents.
Centrifuge
An apparatus having containers for liquids arrayed around a central pivot and rotated at a high speed, thus generating centrifugal force on the liquid, and separating substances (such as particles of solid or globules of an immiscible liquid) mixed together in suspension within the liquid. Suspensions which would settle only very slowly or not at all under gravity can be made to separate quickly in such a device.

Common Curiosities
How does a spindown differ from general centrifugation?
Spindown is a specific type of centrifugation that focuses on rapid sedimentation of particles for quick results.
What types of samples are typically processed using a spindown?
Samples requiring quick sedimentation like cells, precipitates, or particulate matter in laboratory settings.
What is a centrifuge used for?
A centrifuge is used to separate components of a mixture based on density through rotational force.
Can spindown be used for all types of centrifugation tasks?
No, spindown is typically used for rapid tasks requiring less precision and is not suitable for all centrifugation tasks.
Can spindowns be used with any centrifuge?
Spindowns can be performed with any centrifuge that can reach the necessary high speeds, though they are often done with microcentrifuges designed for quick operations.
What are the main benefits of using a centrifuge in a laboratory?
Centrifuges provide flexibility in separation processes, allowing for adjustments in speed and duration to achieve optimal separation for various samples.
How does the speed of a centrifuge affect the separation process?
The speed of a centrifuge affects the centrifugal force applied to the samples, with higher speeds typically resulting in faster and more efficient separation of denser particles from lighter ones.
How does a spindown differ from other centrifugation techniques like ultracentrifugation?
A spindown is typically much quicker and used for less precise separations compared to ultracentrifugation, which is used for very fine separations at much higher speeds.
Why would one choose a centrifuge over a spindown?
One would choose a centrifuge over a spindown for tasks requiring variable speeds and longer run times to achieve desired precision and separation.
What safety precautions should be taken when using a centrifuge?
Safety precautions include ensuring the rotor is balanced, the lid is securely fastened during operation, and the device is maintained regularly to prevent mechanical failures.
Are there specific protocols for using a spindown in research experiments?
Yes, specific protocols must be followed when using a spindown in research, often detailing the exact speed and duration to ensure consistent results across experiments.
What are the limitations of using a spindown?
The limitations include a lack of precise control over separation outcomes and potential damage to sensitive samples due to the high speeds used.
What is the primary advantage of a spindown in clinical settings?
The primary advantage of a spindown in clinical settings is its ability to quickly prepare samples, which is crucial in time-sensitive diagnostic procedures.
What types of industries benefit from using large industrial centrifuges?
