Calculation Of Dilution Factor In Microbiology at Sergio Hoff blog

Calculation Of Dilution Factor In Microbiology. Total volume = (volume of sample +. Aliquots from a stepwise or serial dilution of the original sample are spread on plates. Serial dilution is most commonly used in the microbiology laboratory to reduce microbial concentration through a successive dilution of a sample in a fixed volume of liquid. The ratio of sample, reagent, chemical or compound to diluent is defined as the dilution factor. Determining the dilution factor in serial dilutions can be approached in two ways: The dilution factor is the inverse of the concentration factor. To calculate the dilution factor (df), you need to divide the solution’s total volume by the sample volume (i.e., sugar solution in this case). Multiply the individual dilution factor for the tube and all previous tubes. Determine the dilution factor for each tube in the dilution series. The preparation of dilutions and the calculation and use of dilution factors to obtain the number of microorganisms present in a sample are important basic techniques in microbiology. This has a concentration of 1/10th (0.1) of the original For example, if you take 1 part of a sample and add 9 parts of water (solvent), then you have made a 1:10 dilution; Widely used dilution factors are two and ten, which is why we often talk. For individual test tubes within the series.
