This solution dilution calculator tool from sigma-aldrichcom calculates the volume of stock concentrate to add to achieve a specified volume and concentration using the formula m1v1 = m2v2. The technique used to make a single dilution is repeated sequentially using more and more dilute solutions as the stock solution at each step, 1ml of the previous dilution is added to 9ml of distilled water. Serial dilution technique : this technique is useful for obtaining countable numbers of bacterial colonies by diluting a highly concentrated culture.

Serial dilution method: definition and procedure explained. This calculator is intended for laboratory scale applications although it can also be used for bigger scale applications as well a solution of lower concentration is made by diluting a calculated volume of a solution of higher concentration with solvent (most commonly water) up to a specified volume (the volume of the lower concentration. How to do serial dilutions a dilution in chemistry is a process that reduces the concentration of a substance in a solution a serial dilution is the repeated dilution of a solution to amplify the dilution factor quickly.

There are many ways of expressing concentrations and dilution the following is a brief explanation of some ways of calculating dilutions that are common in biological science and often used at quansys biosciences. Calculate the volumes required to prepare a serial dilution for an assay generates a step-by-step protocol for planning serial dilutions calculates serial dilution using initial concentration and dilution factor or a concentration range main applications include elisa and other microplate-based experiments. Sometimes it is necessary to dilute by a large factor so several serial dilutions are necessary.
