Important Reconstitution Calculations Concepts In this video you will learn the easiest way to solve a difficult looking but fairly straightforward reconstitution calculations question which was asked by a viewer. While reconstitution calculations are fairly easy there are certain types of question that are problematic.

Pharmaceutical preparations are sometimes manufactured as a dry powder to extend shelf-life and reconstitution is the process of adding a special diluent such as sterile water for injection to the dry powder resulting in a solution or suspension.

What is the advantage of performing a serial dilution instead of a single dilution?Įasier and Faster Preparation of Calibration Standards The errors introduced with each successive dilution drops proportionately with the solution concentration. Essential to direct dilution is the ability to accurately transfer extremely small volumes of stock solution, which is generally not possible with pipets. This figure shows only the first four concentrations via direct dilution.

The direct dilution method uses far less sample than the serial dilution method.

Hereof, is direct or serial dilution more accurate? Serial dilutions are used to accurately create highly diluted solutions as well as solutions for experiments resulting in concentration curves with a logarithmic scale. Secondly, what is serial dilution and why is it used? Serial dilution is the stepwise dilution of a substance in solution. Conditions can be adjusted as the experiment progresses (e.g., drug concentrations increased as drug resistance improves). Serial dilution has many advantages: the materials necessary are typically already present in the lab and require no special engineering. Similarly, you may ask, what are the advantages of serial dilution? Clearly, accurate pipetting during preparation of serial dilutions is critical, because any deviation will propagate to all of the subsequent steps. It is much more accurate to make several smaller stepwise dilutions to reach a final concentration when the required reduction in concentration is large.
