Serial dilution

Serial dilution Definition. Serial dilution, as the name suggests, is a series of sequential dilutions that are performed to convert a dense solution into a more usable concentration. In simple words, serial dilution is the process of stepwise dilution of a solution with an associated dilution factor In a single and very simple word, Serial dilution is a laboratory technique, in which a stepwise dilution process is performed on a solution with an associated dilution factor. In the laboratory, this method is used to decrease the counts of cells within a culture to simplify the operation A serial dilution is the repeated dilution of a solution to amplify the dilution factor quickly. X Research source It's commonly performed in experiments requiring highly diluted solutions, such as those involving concentration curves on a logarithmic scale or when you are determining the density of bacteria To perform a serial dilution, a small amount of a well-mixed solution is transferred into a new container, and additional water or other solvent * is added to dilute the original solution. The diluted sample is then used as the base solution to make an additional dilution. Doing this several times results in a range of concentrations 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

SERIAL DILUTIONS - TUBE METHOD Principle Serial dilution is a common technique used in many immunologic procedures. A small amount of serum or solute can be serially diluted by transferring aliquots to diluent. One of the most common series doubles the dilution factor with each transfer (1:2, 1:4, 1:8). These dilutions can be done in microtiter plates or test tubes depending on th A serial dilution is a sequence of dilutions created using the same dilution factor. For instance, creating a two-fold dilution with a starting concentration of 10 µM yields the following concentrations: 10 µM, 5 µM, 2.5 µM, 1.25 µM, etc

In serial dilutions, you multiply the dilution factors for each step. The dilution factor or the dilution is the initial volume divided by the final volume

Serial dilutions are made by making the same dilution step over and over, using the previous dilution as the input to the next dilution in each step. Since the dilution-fold is the same in each step, the dilutions are a geometric series (constant ratio between any adjacent dilutions). For example: 1/3, 1/9, 1/27, 1/81 A serial dilution is a step-wise and geometric series of dilutions which starts with a small amount of starting material and amplifies the dilution factor serially by using diluted material as a source for subsequent dilutions Serial Dilutions . Serial dilutions are often performed when titering antibodies or when generating amplified dilutions of . an analyte.

Do first dilution in sample source well: Begin the serial dilution in the sample wells instead of transferring samples to the target wells before starting the dilutions. Tap Next after the dilutions have been configured. Create a diluent, or select an existing one. Skip this step if you are not pipetting diluent in the Serial Dilution step In serial dilutions, you multiply the dilution factors for each step. The dilution factor or the dilution is the initial volume divided by the final volume. For example, if you add a 1 mL sample to 9 mL of diluent to get 10 mL of solution, DF=ViVf = 1mL10mL=110 Serial dilutions are used to accurately create extremely diluted solutions, as well as solutions for experiments that require a concentration curve with an exponential or logarithmic scale. Serial dilutions are widely used in experimental sciences, including biochemistry, pharmacology, microbiology, and physics


  1. Dilution is the act of mixing a chemical with other substance, usually distilled water to make it lighter in composition. It is usually done if the chemical concentration is too high than the desired composition. Thus, serial dilution simply means a series of repeated dilution performed on the same chemical basically to change its concentration
  2. Making serial dilutions.

From the first tube, take 1ml of the sample and transfer it to the second tube Dilutions: Principles and Applications Dilutions: Principles and Applications Because solutions in science are often much more concentrated than are desired or can be managed for a given protocol, it is frequently necessary to dilute these solutions to a desired level. This requires a working knowledge of the principles of diluting, dilution factors, concentration factors an Background. Serial dilution tests measure the concentration of a target microbe in a sample with an estimate called the most probable number (MPN). The MPN is particularly useful for low. Serial dilution is one of the core foundational practices of homeopathy, with 'succussion', or shaking, occurring between each dilution. In homeopathy, serial dilutions (called potentisation) are often taken so far that by the time the last dilution is completed, no molecules of the original substance are likely to remain. [3] [4

How do you calculate serial dilutions? + Exampl

serial dilution: A serial dilution is used to set up a series of different sample concentrations for an experiment. To accomplish this, a high concentration of sample is used as a starting point. A measured amount of sample is transferred to another well and mixed with dilution solvent, creating a lower concentration Serial dilution is a common technique used in many immunologic procedures. A small amount of serum or solute can be serially diluted by transferring aliquots to diluent. One of the most common series doubles the dilution factor with each transfer (1:2, 1:4, 1:8 ) Serial dilutions follow the same dilution rule as normal dilutions -> M1V1 = M2V2. The initial molarity (or whatever concentration unit you're using - could be Cheerios per spoonful it just has to be the same on both sides of the equation) times the initial volume equals the final molarity times the final volume
