This was a result of an IBM engineer, George T. Judson, requesting to work on a continuous-flow blood centrifuge. He had observed the need for such a machine when visiting NCI in 1962 after his son was diagnosed with leukemia. As a result of this work, IBM developed the NCI-IBM Blood Cell Separator which was announced in 1965. At that ...
There are different types of laboratory centrifuges: Microcentrifuges devices for small tubes from 0.2 ml to 2.0 ml (micro tubes), up to 96 well-plates, compact design, small footprint; up to 30,000 g Clinical centrifuges moderate-speed devices used for clinical applications like blood collection tubes Multipurpose high-speed centrifuges
Whole blood is often separated, using a centrifuge, into components for storage and transport. An application in laboratories is blood separation. Blood separates into cells and proteins (RBC, WBC, platelets, etc.) and serum. DNA preparation is another common application for pharmacogenetics and clinical diagnosis. DNA samples are purified and ...
Continuous flow centrifugation (CFC) historically required two venipunctures as "continuous" means the blood is collected, spun, and returned simultaneously. Newer systems can use a single venipuncture by pooling blood in a vessel and cycling through drawing and returning blood though the needle while the centrifuge continuously processes blood remaining in the vessel.

used in photochemical analysis and quantitative estimation of substances such as blood sugar, creatinine, and hemoglobin. Burette: used to measure the amount of acid or alkali used in titration: General laboratory stands, racks, filter paper, reagents, etc. Induction coils: as a source of high voltage electricity Cathode ray oscilloscope ...
Density gradients for purifying cells are also run in these centrifuges. Swinging-bucket rotors tend to be used very widely because of the huge flexibility of sample size through the use of adaptors. [9] These machines have maximum rotor speeds of less than 10 000 rpm and vary from small, bench-top to large, floor-standing centrifuges. [11]
