• Understanding & Calculating Dilution Factors

  Dilution factor calculation practice -an example (not related to the original question...scroll down for the solution to the original question) When making a fruit smoothie, you combine 100 mL crushed banana, 300 mL milk, and 1 mL vanilla extract.

• Creating Serial Dilutions

  The key to making them serial is to dilute by the same factor each time.
  Steps for serial dilutions are noted. The expert determines how to create serial dilution.

• Dilution and Colony-Forming Units

  You are making dilutions to find a concentration, after which you will have colony forming units. Colony forming units are colonies of bacteria that form from the replication of a single bacteria.

• Dilutions

  An additional 1:10 will make the final dilution factor 1:25 7-3. 1:6 initial dilution for tube 1. Five more 1:2 dilutions are made, making the final dilution factor 1:6*2*2*2*2*2, or 1:192! 7-4.

• Dilution Series for Liquid Culture of Staphylococcus Aureus

  In case you're not quite sure of this, remember that if you do a 1:10 dilution and then another 1:10 dilution, it's like doing a 1:100 dilution; therefore, you multiply the dilution factors.

• Dilution Factors & Serial Dilution

  For the 10^-4 dilution because 0.1 ml is 1/10 (10^-1) of a milliliter the dilution represented on the plate is a 10^-5 dilution, not a 10^-4 dilution, the same goes for the 10^-5 and 10^-6 dilution. The plates were left to incubate for a week.

• Using a Serial Dilution to Count Bacteria in a Sample

  A 1/10 dilution is the same thing as a 0.1 dilution (1 divided by 10 = 0.1) or as a 10-1 dilution. Either way it is written it means the same thing.

• MIC Calculation & Dilution series

  Note: If for some reason you did not do a 1:10 dilution each time, but rather did a 1:100 dilution, then adjust each dilution accordingly. In other words, Tube #2 would end up as 10.0 ug/ml and Tube #3 wold be 0.100 ug/ml, etc.

• Biology Lab - Serial Dilutions and CFUs

  Think about it: The first dilution 1ml was added to 99ml diluent (so a 1:100 dilution), next a 1:10 dilution and then another 1:10 dilution. Thus the total dilution factor would be 100*10*10=10^4 Thus 417 * 10^4= 4.17*10^6 CFUs per ml of yogurt .
