What Are Some Advantages And Disadvantages Of The Serial Dilution Agar Plate Te

Each calibration standard solution is prepared based on the previous calibration standard. The process involves taking a portion of the previous standard and diluting it with the solvent to obtain the next calibration standard. The errors introduced with each successive dilution drops proportionately with the solution concentration. Preparing a series of calibration standards by this method reduces the amount of required time.

Mar 02, 2007  Best Answer: The variance in colonies produced. You get the colony size you need to work with. You do not want your plates to ' lawn ', do you? The advantage of this technique was the generation of a quantitative result (ie, the MIC). The main disadvantage of the microdilution method is some inflexibility of. Appropriate 150-mm agar plate that has been inoculated with a standardized. Has advised Accelr8 Technology and has received research support.

Most calibration standards span a large range of concentrations, so the accuracy of the calibration standard prepared increases. Calibrations Solutions More Evenly Spaced.

The dilution factor chosen for the series of calibration standards is achievable by using serial dilution. The progression of calibration standard concentration is always a geometric series. Yahoo email manager. Consider the example of making the first standard at 1/3 the concentration of the known, the next calibrant would be 1/9th the concentration of the known and the following two calibrants formed are 1/27th and 1/81st. This becomes a much greater advantage when the span of the calibration standards must cover several orders of magnitude in concentration.
