Urine should be spun at a slow speed. Most centrifuges have a radial arm of ~14.5 cm and should be spun at ~1,500 rpm (with a range of 1,000−2,000 rpm) for ~5 minutes (with a range of 3-5 minutes, longer time for slower speeds). Centrifuging the urine at too high of a speed or for a prolonged amount of time can cause artifacts such as cell rupture and cast fragmentation.

What is the best speed to separate a soil sample in a centrifuge?
Very high speed is the best speed to separate a soil sample in a centrifuge.
Centrifuge : inertia :: wheel:?
speed
What are the conditions that affect the microhematocrit value?
The speed and time of the centrifuge directly affect the microhematocrit values. Errors can be caused if it is not spun at the correct speed.
What are the parts of a centrifuge and their functions?
A centrifuge has holes to insert the centrifuge tubes in, a cap to secure the tubes inside, and a lid to protect both the samples and experimenter in case of malfunction. There is also typically a way to set the centrifuge speed and a power switch to turn the centrifuge on and off.
What Quality control must be performed on a centrifuge?
There are two main issues with a centrifuge concerning quality controls. These are the speed of the motor and the smoothness of the spin.
What laboratory apparatus is used to speed up the settling of precipitate?
A centrifuge
Low speed centrifuge and high speed centrifuge?
The terms are relative, like high power and low power for motors. It is relative to RPM. All centrifuge speeds are delineated in RPM. revolutions per minute. The type used in medical labs require specialized centrifuge test tubes (tapered and made of pyrex or some special centrifuge-specific glass). These normally run at a set speed but may have limited speed range control with a directional knob. There are really heavy duty centrifuges which are horizontal axis and look almost like UFOs and have a variety of chemical processing applications.
What test tube is used for separating sediment from urine?
The tube is not so important . It's the centrifuge that does the work.
What is the structure and function of a serofuge?
A serofuge is a small centrifuge specifically designed to separate serum from cells and to complete blood cell washing procedures. Like a centrifuge, a serofuge has holes to insert the centrifuge tubes in, a lid to protect both the samples and experimenter in case of malfunction, and a way to set the centrifuge speed and way to turn the centrifuge on and off.
What is the optimal speed to centrifuge and collect cells?
It depends on the density of the medium in which the cells are suspended.
What is clinical centrifuge?
Clinical centrifuge are devices used for clinical applications like blood collection tubes. These laboratory equipment are driven by motor and spins liquid samples at high speed.
What is the Process of seperating cell parts by spinning cells in a tube at high speed?
using the Centrifuge
