The purpose of this method is to separate out the lysozyme by Dilution Series Lab Report weight. Fragile X Syndrome Analysis certain for instances, the Dilution Series Lab Report of microorganisms in a Dilution Series Lab Report over a period of time, is an important.

IS lab experiment SERIAL DILUTION

The main purpose of this experiment was to use of serial dilution-agar plate technique in order to determine the number of cells in bacterial culture. It was expected that the number of colonies in each A and B agar plate would be close to each other. However, it is impossible to suggest the exact number of cells in each plate. First of all, 1 ml of bacterial suspension was aseptically transferred to tube 2 by sterile fresh pipette. This step was repeated for tubes 3, 4, 5, 6, 7, 8. Secondly, 0. Finally, diluted bacterial cultures in plates were spread by bent glass rod on the whole surface of agar plate. Serial dilution-agar plate technique counts only viable cells whereas other methods count both viable and dead cells.

Dilution is the process which involved making the solution weak or less concentrated. Dilution factor is the amount of solvent required to reach a given concentration of solution for a given volume. Advantages: only viable cells are counted; it allows isolation of discrete colonies which can be then subcultured into pure cultures. Disadvantages: overnight incubation is needed before colonies develop on agar surface; there may be errors in dilution or plating. Chemical methods may be used to measure increases in protein concentration and DNA production. Measurement of certain metabolic parameters can be used to enumerate the bacterial population. For example, aerobic cells: increase in the amount of oxygen uptake shows the increasing number of aerobic cells; anaerobic cells: rate of carbon dioxide production is related to increased growth of anaerobes.

This process keeps the amount of solute constant, but increases the total amount of solution, thereby decreasing its final concentration. Dilution can also be achieved by mixing a solution of higher concentration with an identical solution of lesser concentration.

Diluting solutions is a necessary process in the laboratory, as stock solutions are often purchased and stored in very concentrated forms. For the solutions to be usable in the lab for a titration, for instance , they must be accurately diluted to a known, lesser concentration. The volume of solvent needed to prepare the desired concentration of a new, diluted solution can be calculated mathematically. The relationship is as follows:. M 1 denotes the concentration of the original solution, and V1 denotes the volume of the original solution; M 2 represents the concentration of the diluted solution, and V2 represents the final volume of the diluted solution.

When calculating dilution factors, it is important that the units for both volume and concentration are the same for both sides of the equation. Serial dilutions involve diluting a stock or standard solution multiple times in a row. Half of the PCA. PURPOSE: To familiarize ourselves with scientific notation and the process of using serial dilutions to make concentrations of known values. I put on my goggles, apron and tied my hair back so that it wouldn't get caught on anything during the lab.

Second, my group and i read over the directions and what materials we needed to get from the cart to perform the experiment. As soon as we got our materials. Get Access.
