take 1 ml, add 9 ml water.
Add 2 mL of culture to 20 mL of buffer. 2/20 = 1/10
what is dilution rate for glycos
A dilution ratio is normally used for a mixture of two fluids: an active component and a carrier solvent. The dilution ratio is the ratio of the volume of the solvent to the volume of the active component.
1 part of solution A plus 99 parts solution B
In chemistry and biology, the dilution factor is the total number of unit volumes in which the material is dissolved. As I understand it, the dilution refers to the dilution ratio. If you add 1 part of something to 4 parts of something else, the dilution ratio is 1 to 4. The dilution factor counts all the parts and expresses the same thing as 1 out of 5.
You add 9.09ml of stock solution to a volumetric and make it up to 1 litre to get a 110 dilution
To make a 1 to 5 dilution you mix 1 part of your substance with 4 parts water. ie: Mix 1 tablespoon of creamer with 4 tables spoons of coffee, and the coffee is 1/5 creamer now.
To make a 500 dilution, add 1 part of the substance you are diluting to 499 parts of water. For example, if you have 1 mL of the substance, you would add 499 mL of water to make a total volume of 500 mL for the dilution.
take 1 ml, add 9 ml water.
2 times dilution from 100% acetone
Yes
measure 1 ml of the original solution and add 6.6 ml of distilled water.
1:2 dilutions
Concentration factor, CF = 1/Dilution factor, DF if DF = 5 then CF = 1/5 CF = 0.2
1:2 means "1 part to 2 parts", so if the "1 part" is what you are diluting, it is actually a 1/3 dilution (one part into 3 parts total). On the other hand, 1/2 means "1 part into 2 parts total", and in the colon nomenclature that would be a 1:1 dilution.
1 ml solute to 19 mls solvent. This gives a total volume of 20 (20 fold)
