It is a mixture of 1 part of the active ingredient (by volume) to 10 parts of the solvent.
An 8-fold dilution means you are making your solution 1/8 less concentrated. So, if you want to make 100 ml of a solution diluted 8 fold you would do as follows: 1/8=.125 100*.125= 12.5 Mix 12.5 mL of your concentrated solution with 87.5 mL of your solvent (water etc..) to bring the final volume to 100 mL. If you wanted to perform a ten fold dilution you would simply mix 10 mL of your concentrated solution with 90 mL of your solvent. 1/10=.1 100*.1=10
If you mean 10 to the power of -1 then it is equal to 1/10
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.
Assuming you mean 10/20, (10/20)/(4-5)=0.5/-1=-1/2 Assuming you mean 10.20, 10.2/-1=-10.2 Assuming you mean 10-20, (10-20)/(-1)=(-10)/-1=10
1X PBS might mean 1 in 10 solution 1/10
Add 2 mL of culture to 20 mL of buffer. 2/20 = 1/10
Means that there is no dilution.
1 in 25. (10/250)
dilution rate RTU
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.
take 1 ml, add 9 ml water.

An 8-fold dilution means you are making your solution 1/8 less concentrated. So, if you want to make 100 ml of a solution diluted 8 fold you would do as follows: 1/8=.125 100*.125= 12.5 Mix 12.5 mL of your concentrated solution with 87.5 mL of your solvent (water etc..) to bring the final volume to 100 mL. If you wanted to perform a ten fold dilution you would simply mix 10 mL of your concentrated solution with 90 mL of your solvent. 1/10=.1 100*.1=10
You add 9.09ml of stock solution to a volumetric and make it up to 1 litre to get a 110 dilution
