  2. Serial dilution - Wikipedia

    en.wikipedia.org/wiki/Serial_dilution

    A serial dilution is the step-wise dilution of a substance in solution, either by using a constant dilution factor, or by using a variable factor between dilutions. If the dilution factor at each step is constant, this results in a geometric progression of the concentration in a logarithmic fashion.

  3. Dilution (equation) - Wikipedia

    en.wikipedia.org/wiki/Dilution_(equation)

    Diluting a solution by adding more solvent. Dilution is the process of decreasing the concentration of a solute in a solution, usually simply by mixing with more solvent like adding more water to the solution.

  4. Homeopathic dilutions - Wikipedia

    en.wikipedia.org/wiki/Homeopathic_dilutions

    Serial dilution of a solution results, after each dilution step, in fewer molecules of the original substance per litre of solution. Eventually, a solution will be diluted beyond any likelihood of finding a single molecule of the original substance in a litre of the total dilution product.

  5. Titer - Wikipedia

    en.wikipedia.org/wiki/Titer

    Titer (American English) or titre (British English) is a way of expressing concentration. [1] Titer testing employs serial dilution to obtain approximate quantitative information from an analytical procedure that inherently only evaluates as positive or negative.

    Serial dilution, stepwise; Homeopathic dilution; Dilution (equation), an equation to calculate the rate a gas dilutes; Trademark dilution, weakening of a trademark by unauthorised use; Stock dilution, issuing of new company shares; Dilution gene, lightening animal coat color; Expectational Dilution, album by Overcast; Dilution ratio

  7. Dilution ratio - Wikipedia

    en.wikipedia.org/wiki/Dilution_ratio

    The "dilution factor" is an expression which describes the ratio of the aliquot volume to the final volume. Dilution factor is a notation often used in commercial assays.

  8. Isolation (microbiology) - Wikipedia

    en.wikipedia.org/wiki/Isolation_(microbiology)

    Depending on the expected density and viability of microbes present in a liquid sample, physical methods to increase the gradient as for example serial dilution or centrifugation may be chosen. In order to isolate organisms in materials with high microbial content, such as sewage, soil or stool, serial dilutions will increase the chance of ...

  9. Miles and Misra method - Wikipedia

    en.wikipedia.org/wiki/Miles_and_Misra_method

    The sectors are labelled with the dilutions. In each sector, 1 x 20 μl of the appropriate dilution is dropped onto the surface of the agar and the drop allowed to spread naturally. In the original description of the method a drop from a height of 2.5 cm spread over an area of 1.5-2.0 cm.
