Some techniques operate and are applicable to a wide range of concentrations of the species in question. A windows version of the same application is available as part of a larger program (8). To ensure the accuracy of your results, chemical analysis requires you to calibrate your instruments. A video demonstration of the downloading instructions and use of the Android application is available at.

#SERIAL DILUTION FOR FREE#
An Android application for the dilution/Serial dilution instructions, developed based on the MDE and named as “TheDilutionApp” is now available for free for a limited period at "/bbassa9824/TheDilutions/releases". The equation is useful when the volume of the stock solution made up to the final volume as calculated with basic dilution equation is not measurable physically. The equation is D = C1p/C2V2, where D is the fold dilution required of a stock solution of C1 concentration which is diluted and delivered (pipetted) at a volume p to cell culture media, assay mixture etc., of volume (V2 – p), to achieve a final concentration of C2. We demonstrate with examples how the equation can be used in delineating serial dilution steps either manually or through programming. We present here a modified dilution equation (MDE) that has the delivered volume as one of the variables.
The best solution to this dilemma is to develop an equation with the delivery volume as one of the variables. The basic dilution equation (C1V1 = C2V2) alone is not amenable for the programming and computerization of the serial dilutions. Stock solutions made with accurately weighable quantities of biologically active compounds often do not result in physically measurable delivery volumes, delivered to cell cultures, assay buffers etc., consequently requiring delineation of the serial dilution steps of the stock solution in a case by case manner.
