Department of Immunology Microbiology and Parasitology You have to prepare 150 ml of the 10-1 dilution from a water sample. Devise a scheme to prepare.

to perform this serial dilution is 1 mL of undiluted solution In cell culture and microbiology laboratories they may be used to suspend cells. In.

The concentration of a solution is how much of the solute While serial dilutions are a great way to save on both reagents and space in the lab.

problem the concentration of each dilution will be expressed in the same unit as that used in the original solution The calculations used to determine the concentration of each solution in a series may be used in reverse to produce a dilution series having prescribed concentrations at each step

Serial Dilution Protocols convenient inoculate volume in terms of spreading absorption and calculations is 0 01 ml (10 microliters) Some bacteria rapidly attach to the agar surface so the plates should be tipped soon after delivery Working from the most dilute suspension to the most concentrated is advised

In microbiology serial dilutions (log dilutions) are used to decrease a bacterial concentration to a required concentration for a specific test method or to a concentration which is easier to count when plated to an agar plate

In this method serial dilutions of a sample containing viable microorganisms are plated onto a suitable growth medium The suspension is either spread onto the surface of agar plates (spread plate method) or is mixed with molten agar poured into plates and allowed to solidify (pour plate method)

The dilution of a sample in a diluent (the liquid used to dilute the sample) can be calculated as: For example if 1 mL of a sample was diluted by adding it to 9 mL of water (diluent) then: In microbiology dilutions are usually reported as exponents For example: 1/10 = 10-1 1/100 = 10-2 1/1000 = 10-3 1/10000 = 10-4 and so on

Serial dilutions can be used to prepare solutions of any desired concentration no matter how dilute You will perform a simple exercise to be sure you understand how to do this as it will be important in your future biological research endeavors In a pinch here’s a Serial Dilution Calculator: https://www aatbio com/tools/serial-dilution
