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. For example, in solution with a 1/5 dilution factor (which may be abbreviated as x5 dilution ), entails combining 1 unit volume of solute (the material to be diluted) with ...
Homeopathic dilutions. In homeopathy, homeopathic dilution (known by practitioners as "dynamisation" or "potentisation") is a process in which a substance is diluted with alcohol or distilled water and then vigorously shaken in a process called "succussion". Insoluble solids, such as quartz and oyster shell, are diluted by grinding them with ...
Dilution (equation) 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. To dilute a solution means to add more solvent without the addition of more solute. The resulting solution is thoroughly mixed so as to ensure that all parts of ...
In microbiology, the minimum inhibitory concentration ( MIC) is the lowest concentration of a chemical, usually a drug, which prevents visible in vitro growth of bacteria or fungi. [ 1][ 2] MIC testing is performed in both diagnostic [ 1][ 2] and drug discovery laboratories. [ 3][ 4] The MIC is determined by preparing a dilution series of the ...
The laws of chemistry give this dilution limit, which is related to the Avogadro number, as being roughly equal to 12C homeopathic dilutions (1 part in 10 24). [113] [148] [149] James Randi and the 10:23 campaign groups have highlighted the lack of active ingredients by taking large 'overdoses'. [150]
If you raise a new round of venture capital (say $2.5 million at a $7.5 million pre-money valuation, which is a $10 million post-money) you get diluted by 25% (2.5m / 10m). So you own 15% of the ...
The TCID 50 (50% Tissue Culture Infectious Dose) assay is the measure of infectious virus titer. This endpoint dilution assay quantifies the amount of virus required to kill 50% of infected hosts or to produce a cytopathic effect in 50% of inoculated tissue culture cells. This assay may be more common in clinical research applications where the ...
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. The titer corresponds to the highest dilution factor that still yields a ...
