Laboratory Math II: Solutions and Dilutions
Let's take a look at this particular serial dilution in cartoon form. We start with a stock solution with a high concentration. We determined we would perform

concentration use the equation that follows. Prepare a 1:10 serial dilution of the concentrated (300 mg/mL) stock according to Table 3.5.
PREPARING SOLUTIONS AND MAKING DILUTIONS
A serial dilution is simply a series of simple dilutions which amplifies the dilution Example 1: Suppose you have 3 ml of a stock solution of 100 mg/ml ...
2 Amount and concentration: making and diluting solutions
The concentration of this solution could be described as. 0.009 g/mL or 9 mg/mL. Alternatively you could notice that if 0.9g is dissolved in 100mL then 9g

Making Dilutions - UMass
Figure 1 A serial dilution A small volume (vt) of solution is transferred to a vessel containing a volume (vf) of solvent After these are mixed vt of the second solution is transferred to the third vessel also containing vf of solvent The concentration of each solution is 1/d the concentration of the previous one in the series
Microbiology BIOL 275 DILUTIONS - University of Pennsylvania
What is the serum dilution? Set up the problem as 5 ml serum + X ml saline = 25 ml of the final solution = 25 - 5 = 20 ml of saline The serum dilution is the amount of serum in the amount of total solution; hence this is a 5/25 serum dilution which would equal a 1/5 dilution Titer
How do you do a 100 fold dilution? - Frank Slide - Outdoor
A serial dilution is simply a series of simple dilutions which amplifies the dilution factor quickly beginning with a small initial quantity of material (i e bacterial culture a chemical orange juice etc ) The source of dilution material for each step comes from the diluted material of the previous In a serial dilution the total dilution
Biotech 2 – Making Serial Dilutions - Los Angeles Mission
Serial dilutions can be accomplished very quickly and easily once you have made a plan Planning a serial dilution involves 3 steps: 1 Determine the dilution factors you want for each dilution (e g 1/10 or 10-1) • You typically want the dilution factor to be the same for each dilution
Dilution factor: 10X
11 Calculate the dilution factors you created To calculate the dilution factor you would use the equation: Total Volume/Volume of stock solution added = Dilution Factor In the table in Step 3 above the example dilution factor would be 1000/500 = 2 so a 2X dilution was done

How do you do a 100 fold dilution?
- How do you do a 100 fold dilution? For a 1:100 dilution, one part of the solution is mixed with 99 parts new solvent. Mixing 100 µL of a stock solution with 900 µL of water makes a 1:10 dilution. The final volume of the diluted sample is 1000 µL (1 mL), and the concentration is 1/10 that of the original solution. How do you fold a dilution?
What does 1 in 5 dilution mean?
- What does a 1 in 5 dilution mean? Answer: 1:5 dilution = 1/5 dilution = 1 part sample and 4 parts diluent in a total of 5 parts. If you need 10 ml, final volume, then you need 1/5 of 10 ml = 2 ml sample.
What is a 1 1000 dilution?
- What is the dilution factor of 1 1000? You could make 1/1,000 by adding 1 microliter of sample to 0.999 ml diluent. Why is that a poor choice? Because you can’t measure 1 microliter (or even 10 microliters) accurately with ordinary pipeters. So, make three serial 1/10 dilutions (0.1 ml [100 microliters] into 0.9 ml): 1/10 x 1/10 x 1/10 = 1/1,000.
How do you calculate solution concentration?
- To calculate the concentration of a solution, start by converting the solute, or the substance being dissolved, into grams. If you're converting from milliliters, you may need to look up the solute's density and then multiply that by the volume to convert to grams. Next, convert the solvent to liters.
