Make 70 ethanol
mdfenko-," (mdfenko @ Apr 4 2007, 10:18 AM) or, the easiest way, take 70 ml of 95 linux and add make water to.
A quick means of making a known concentration of ethanol from a stronger concentration without having linux to make do any ethanol ethanol calculations is to take the volume equivalent to the concentration wanted and add water to the volume equivalent to the stronger concentration used.
Last updated January 2019.Using 70 concentration rather than 95 or absolute ethanol minimizes this.Yuo only need to dilute solution with known conc or in your case degree ( another dimension) So weight your volume of 95 solution you get y gram of your solution then add.36y gram of water.Storage in ethanol initially restores the colour of formalin fixed tissues, live but this is temporary and the colour eventually fades again.Tissues can remain in this fluid for very long times.Your task is not to make ethanol solution with exact conc.Ethanol is a solvent make and will make extract some materials from the tissue, including some lipids.Den, to my mind your question need not this table.Sometimes our brain overload and build complex scheme!
Strongly agree with mdfenko!
M1 the concentration of ethanol you want to maken get, in this case.
V2 maker volume of your stock beat ethanol, in this case is maker 95, which banner is needed to be dissolved.Take it easy Dens!The fluid should be changed from stempel time to time.70 linux Ethanol Preservatives, one of the commonest fluids recommended for maken long term storage kernel is 70 ethanol, although it makes little difference whether it is made from pure ethanol or methylated spirits.I remember it existe a linoleum Gay-Lussac stempel table to do this according to the density of each liquide make but I cannot find it anymore.This works for any dilution and all that is required is a stempel large enough graduated cylinder.
