Volume

Volume

1. A roll; a scroll; a written document rolled up for keeping or for use, after the manner of the ancients. The papyrus, and afterward the parchment, was joined together [by the ancients] to form one sheet, and then rolled upon a staff into a volume (volumen). (Encyc. Brit)

2. Hence, a collection of printed sheets bound together, whether containing a single work, or a part of a work, or more than one work; a book; a tome; especially, that part of an extended work which is bound up together in one cover; as, a work in four volumes. An odd volume of a set of books bears not the value of its proportion to the set. (Franklin)

4. Anything of a rounded or swelling form resembling a roll; a turn; a convolution; a coil. So glides some trodden serpent on the grass, And long behind wounded volume trails. (Dryden) Undulating billows rolling their silver volumes. (W. Irving)

4. Dimensions; compass; space occupied, as measured by cubic units, that is, cubic inches, feet, yards, etc.; mass; bulk; as, the volume of an elephants body; a volume of gas.

5. Amount, fullness, quantity, or calibre of voice or tone.

(Science: chemistry) atomic volume, molecular volume, the ratio of the atomic and molecular weights divided respectively by the specific gravity of the substance in question.

(Science: physics) specific volume, the quotient obtained by dividing unity by the specific gravity; the reciprocal of the specific gravity. It is equal (when the specific gravity is referred to water at 4 deg c. As a standard) to the number of cubic centimeters occupied by one gram of the substance.

Origin: f, from L. Volumen a roll of writing, a book, volume, from volvere, volutum, to roll. See voluble.

Problems making chemically competent cells

... overnight from a single colony, in SOC medium 2. The next day, inoculate 100ml pre-warmed SOC medium with 5ml of the overnight pre-culture. The volume of the flask here is important for aeration. I use a 2 litre baffled flask for improved aeration (volume of medium 1/10 or 1/30 volume of the ...

Re: Lipid Bilayers vs Micelles

... however, the hydrophobic tails have a greater cross-sectional area than the heads, and so they cannot form stable micelles - in other words, the volume of the interior of a hypothetical phospholipid micelle would not allow the hydrophilic heads to make a continuous, unbroken surface. The simplest ...

The same old silly question about molarities

... Cellulase and so on... I know how to prepare each stock solution individually but how can I translate all these molarites and percentages into one volume to work with? lets say I need 10 ml of this enzyme solution with the mentioned contents. Thank you very much for your help.

conversion

nmol is amount (of molecules), while microlitr is volume. There is no conversion. You need to tell us about the concentration.

Increasing the amount of bacteria per ml in a suspension

What about to spin your bacteria and resuspend in 1/100 of volume? :roll:
