Dilutions - Part 3 of 4 (Calculating Colony Forming Units/ml) - Duration: 6:51. SJU GEP Science 154,083 views.
Dilution factor is the final volume / aliquot volume.
Aliquot volume is the measure of sub volume of original sample.Final volume is the total volume.
Dilution factor =final volume /aliquot vol.
for example ; what is the df when you add 2ml sample to8m???
total vol is 2+8=10
DF=total vol/aliquot.
10/2=5
So 5 is dilution factor
Distinguish between dilution and dilution factor?
Dilution is the process of making a less concentrated solution and dilution factor is the amount of solvent required to make a certain concentration of solution.
What is the formula used for counting CFU ml?
cfu/ml = (no. of colonies x dilution factor) / volume inoculated
Definition of dilution and dilution factor?
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.
What is dilution factor?
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.

What is concentration factor when dilution factor is 5?
Concentration factor, CF = 1/Dilution factor, DF if DF = 5 then CF = 1/5 CF = 0.2
What is the Formula for manual blood cell count?
Total count = (cells counted x dilution factor)/(area x depth)
What factor affect pH of buffer?
What is the formula used to calculate dilution ratios?
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.
What is the total dilution factor from 1.00 M NaCl to 1.00 M NaCl solution?
What are two examples of dilute solution?
Example 1: Frozen orange juice concentrate is usually diluted with 4 additional cans of cold water (the dilution solvent) giving a dilution factor of 5, i.e., the orange concentrate represents one unit volume to which you have added 4 more cans (same unit volumes) of water. So the orange concentrate is now distributed through 5 unit volumes. This would be called a 1:5 dilution, and the OJ is now 1/5 as concentrated as it was…
In the calculation trypan blue exclusion assayof haemocytometer why dilution factor 2 is used not 0.5?
Because you probably used a 2-fold dilution. So you need to multiply your count by 2 to get the ACTUAL amount.

What percent by volume of acid is in dilute sulfuric acid?
The answer depends on the dilution factor and if the sulfuric acid was 100% to start.
What is the molarity of the resulting solution when 300 mL of a 0.600 M aqueous solution is diluted by the addition of 400 mL of water?
This is a simple case of applying a dilution factor. Your dilution factor is 7/3. i.e. you have a concentration that is 3/7 of what it was (i.e. 300/(300+400)). 0.6/7*3 is 0.25714M.
What is the effect of dilution on viscosity of oil?
dilution will reduce the viscosity The effect of dilution on viscosity of oil is that it will decrease.
