Let stand a few minutes, and revolve in thecentrifuge until the bulk of precipitate remains constant.
Centrifugalize thoroughly and pour off all the clear fluid into a graduated centrifuge tube.
Let stand a few minutes for a precipitate to form, and then revolve in thecentrifuge for three minutes at 1200 revolutions a minute.
This is revolved in the centrifuge at 1000 revolutions a minute for three minutes, or until the fat has separated.
The apparatus consists of a special tube which fits the aluminum shield of the medical centrifuge (Fig.
The electric centrifuge is to be recommended, although good work can be done with a water-power centrifuge, or, after a little practice, with the hand centrifuge.
If a centrifuge is not available, the urine may be allowed to stand in a conical test-glass for six to twenty-four hours after adding some preservative (p.
Purdy, the centrifuge offers an important means of making quantitative estimations of a number of substances in the urine.
Then you should be glad to hear the power-up simulation in the centrifuge this morning took me right through Mach 9.
This morning's run-up in thecentrifuge had gone well.
The centrifugeitself was pure white enamel, spotless, just like the room.
He waited a few seconds longer, till the huge white centrifugehad come to a complete stop, then shoved down the metal hatch release and stepped out.
The former force is called by French writers the force centrifuge ordinaire, and the latter the force centrifuge composee, or force de Coriolis.
If this phenol-purified RNA is dissolved in a concentrated sugar solution and spun in a centrifuge at a very high velocity, it will separate into three major components.
We can also identify a third component, m-RNA, with the centrifuge system but only with some difficulty and only after labeling it with a radioactive precursor, because the amount of m-RNA in a cell is very small.
The rotors, in fact, would be floated in oil just as the high-speed centrifuge the Chief had mentioned had floated on compressed air.
A special test bottle and centrifugeare necessary.
These pockets are hinged so that when standing still the bottle is in an upright position and when the centrifuge is running, it is in a horizontal position.
For example, the centrifuge used in the butterfat test, discovered in 1890 by Stephen M.
A centrifuge used for running the Babcock milk test, which determined the percentage of butterfat.
Remove as much of its blood as possible from the heart under aseptic precautions into sterilized centrifuge tubes.
Blood to the volume of several cubic centimetres will now drop from the punctured vein, and should be caught in a tapering centrifuge tube, the tube transferred to the incubator at 37° C.
Take a small centrifugetube and half fill it with sodium citrate solution.
Allow the tube to stand for a few minutes so that the large masses of growth may settle down; transfer the upper portion of the saline suspension to a centrifuge tube and centrifugalise thoroughly.
Transfer it to a sterilecentrifuge tube and place the tube in the incubator at 37° C.
Apparatus: Small centrifuge and tubes for same (made from the barrels of broken capillary pipettes by sealing the conical ends in the bunsen flame).
The introduction of improved forms of the centrifuge has brought the second method of securing a sediment into preference.
It is not necessary to wash the crystals in the centrifuge until they are white.
The crystals are then transferred to a small laboratory centrifuge and centrifuged for several minutes.
The crystals are washed in thecentrifuge with about 15-25 cc.
If an efficient centrifuge is available for use at this stage of the operation, this separate washing may prove to be less essential.
I put the whole gate on the centrifuge and swung it up to twelve gees" I said.
I've got the problem of an expensive training centrifuge about beat.
First there was the dizzying, mind-blackening centrifuge test, to see if you could take enough Gs of acceleration, and still be alert enough to fit a simple block puzzle together.
This process naturally removes the solid impurities as dirt, hairs, epithelial scales and cells, also some of the casein, making what is known as centrifuge slime.
This digestive ferment may be separated from fresh milk by concentrating centrifuge slime extracts by the usual physiological reagents.
Only one of the score of men in the centrifuge tank remained voluntarily in his cot.
The huge headquarters base centrifuge aboard the man-made satellite had gradually caused their bodies to respond once more to a single source of pull.
Subsequent centrifuge studies showed that its vascular responses exceeded those of a control group.
The surface of this centrifuge is parabolic, so that the resultant of the centrifugal g and the Earth's gravity is always normal to the surface.
It also can be increased by using a centrifuge which adds a radial acceleration vector to the 1 g of Earth.
