Problem set 8.8

51. A centrifuge rotor has a moment of inertia of 3.15 x 10^-2 kg m^2. How much energy is required to bring it from rest to 8000 rpm? The energy required would be the kinetic energy it has when you are done: w = (8000 Revolutions/Minute)(2 p radians/revolution)(1 minute/60 sec) = 837.76 rad/s I = 3.15x10-2 kgm 2 E k rot = 1 / 2 I w 2

Fixed Angle Centrifuge Rotors - Beckman Coulter

Fixed Angle Centrifuge Rotors. Fixed-angle rotors feature a medium pathlength, a fast run time and excellent resolution. In fixed-angle rotors, tubes are held at a constant angle during the spinning operation, typically between 23 – 38 from vertical. They’re commonly used at higher speeds, for small to large volumes, for pelleting applications, such as bacteria and yeast to …

Overview of blood components and their preparation - PMC

INTRODUCTION. Blood is a lifesaving liquid organ. Whole blood is a mixture of cellular elements, colloids and crystalloids. As different blood components have different relative density, sediment rate and size they can be separated when centrifugal force is applied.[]In increasing order, the specific gravity of blood components is plasma, platelets, leucocytes (Buffy Coat [BC]) and …

Centrifugation - Wikipedia

The conversion factor between RPM and g depends on the radius of the centrifuge rotor. The particles' settling velocity in centrifugation is a function of their size and shape, centrifugal acceleration, the volume fraction of solids present, the density difference between the particle and the liquid, and the viscosity. The most common ...

7422 - Gene ResultVEGFA vascular endothelial growth factor ...

This gene is a member of the PDGF/VEGF growth factor family. It encodes a heparin-binding protein, which exists as a disulfide-linked homodimer. This growth factor induces proliferation and migration of vascular endothelial cells, and is essential for both physiological and pathological angiogenesis. Disruption of this gene in mice resulted in abnormal embryonic blood vessel …
