Multiply by dilution factor
Web2 sept. 2002 · Multiply the count obtained in (2) by the dilution factor. Example: Assume that you dilute the original semen sample by adding 0.1 ml of semen to 9.9 ml of diluent (1:100 dilution factor). You then count the number of sperm in 5 of the 25 large squares within the central counting area of two chambers, obtaining counts of 132 and 128 cells. WebThe titer in tube 4 can be calculated by multiplying the dilution factors of all the dilutions used. Here's how you can do it: The initial dilution is 1:4 with saline, which means 1 part serum is mixed with 4 parts saline. ... Now, to calculate the titer in tube 4, we multiply all the dilution factors together:

A Serial dilution is a series of dilutions, with the dilution factor staying the same for each step.The concentration factor is the initial volume divided by the final solution volume. The dilution factor is the inverse of the concentration factor. For example, if you take 1 part of a sample and add 9 parts of water (solvent), then you have …
WebDilutions are often made serially, although this is not the best approach as any errors made with each dilution are compounded. Results can be displayed by several methods, of which the simplest is to calculate the final concentrations by multiplying by the appropriate dilution factor and plotting these against dilution. WebThese two components proportionally combine to create a dilution. For example, a 1:20 dilution converts to a 1/20 dilution factor. Multiply the final desired volume by the dilution factor to determine the needed volume of the stock solution. In our example, 30 mL x 1 ÷ 20 = 1.5 mL of stock solution. Why do you make a calibration curve?
This method is called multiplying by the inverse (of the dilution factor). 1. If the dilution factor is in the form of a fraction, “flip” the fraction. (i.e., 1/50 becomes multiply by 50/1). 2. If the dilution factor is in decimal form, multiply by 1 over the decimal. (i.e., 0.02 becomes multiply by 1/0.02).
