Centrifuges

Centrifuges use centrifugal force to separate particles based on their density, size, and shape. This makes them ideal for separating blood cells, isolating proteins, purifying DNA, and more. Whether you’re separating cells for analysis, isolating proteins for research, or purifying DNA for production, our centrifuges will help you achieve your goals.

FREQUENTLY ASKED QUESTIONS

What is a centrifuge?

A centrifuge is a laboratory device that uses centrifugal force to separate components of a mixture based on their density. 

How to calibrate a centrifuge?

To calibrate a centrifuge, first ensure it’s clean and balanced. Check the tachometer accuracy using a calibrated tachometer or strobe light. Verify the timer accuracy with a stopwatch. Adjust settings if necessary and document the calibration process.

What is a centrifuge used for in science?

In science, a centrifuge machine is used for separating components of a mixture based on density, isolating cellular components, purifying chemicals, and analysing particle size distributions.

How does a centrifuge separate mixtures?

A centrifuge separates mixtures by spinning samples at high speeds, creating centrifugal force. Denser particles move outward, while lighter ones remain closer to the centre, allowing for separation based on density differences.

How does a centrifuge work to separate blood?

In blood separation, centrifugal force causes denser red blood cells to move to the bottom of the tube, while lighter plasma rises to the top. White blood cells and platelets form a layer (buffy coat) between these two components.

How long to centrifuge blood for plasma?

To centrifuge blood for plasma, typically spin the sample at 1000-2000 x g for 10-15 minutes. However, exact time and speed may vary depending on the specific protocol and centrifuge lab equipment  type.
