Elutriation

Elutriator JE 5 0 Rotor. Elutriation is a centrifugation technique that aims to separate particles based on size and density. This is achieved through an elutriation rotor. An elutriation rotor is designed to separate and/or concentrate monodisperse suspensions of single cells or particles according to size (approximately 2 to 50 µm in diameter).

What is Centrifugal Elutriation

Centrifugal elutriation was invented by Charles Lindberg in the 1930s. This technique continuously separates cells according to their sedimentation velocity using a specialized centrifuge rotor. A specialized rotor loads cells into a spinning elutriator chamber introducing an opposing directional buffer (opposite direction of centrifugal force ...

Elutriated lymphocytes for manufacturing chimeric antigen …

We investigated the use of PBMC concentrates enriched for lymphocytes using elutriation for manufacturing 8 CD19- and 5 GD2-CAR T cell products. Results: When compared to PBMC concentrates, lymphocyte-enriched elutriation fractions contained greater proportions of CD3+ and CD56+ cells and reduced proportions of CD14+ and CD15+ cells. All 13 CAR ...

Techniques

The efficiency of the hydropneumatic root elutriation technique was higher for clay soil and was comparable with the other techniques for loam and sand. In general, 92–95% of the sclerotia added to soils were recovered with the root elutriation technique. Wet sieving was the least precise, most biased, least efficient, and gave the lowest ...
