Serial Dilution Activity Many applications require the determination of microbial numbers. Those applications can be either clinical or in a research setting. Clinical applications include determination of antibiotic efficacy and as well as therapy. Research applications include determination of the effectiveness of antimicrobial chemicals‚ radiation‚ etc. The viable count is most common or standard method used to quantitate bacteria. With this method only microbes that are alive and able to reproduce

1) Why serial dilutions are preferred to one large dilution in lab experiments? Answer: Serial dilution is the technique of performing repeated dilutions on the same chemical in order to change its concentration. The diluted solution from a serial dilution can be used to calculate the concentration of the actual solution. In experimental work‚ often we need to obtain a range of concentrations for a specific compound. Thus‚ instead of preparing one large dilution‚ if we take a concentrated sample

First of all “A serial dilution is a series of sequential dilutions used to reduce a dense culture of cells to a more usable concentration . Each dilution will reduce the concentration of bacteria by a specific amount” .( Study . com / Serial Dilution ) A serial dilution is any dilution were the concentration decrease by the same quantity in each successive step . The purpose of serial Dilution is to reduce the concentration of cells

1. Introduction: The goal of this lab was to demonstrate the microbiology technique of serial dilutions and how they can effectively be used in experiments. E. coli cells were exposed to UV light for various amounts of time in order to asses the effect on growth and thereby mutations since this cell was modified to not have photolyse no uvr genes for DNA repair and thus can only use the SOS response. Each group then diluted the cells accordingly based on their UV exposure time and counted the cells

Vocabulary: Lesson pH and dilutions Science Starter: Determine the pH of .0103M H3PO4 solution in water. Remember to look at the H+ count. Box 1 In a dilution‚ the number of solute particles does not change‚ just the concentration with respect to the volume. This relationship is _____________________ proportional. Initially‚ there is 275mL 0.125M stock solution of a substance. -Determine the amount of moles of solute present. -What is the concentration after a dilution when the final volume is 2

a huge problem and much more difficult to solve. As the number of vehicles increase day-by-day‚ a lot of malpractices in this field happen‚ such as stealing vehicles‚ red light violations‚ unnecessary accidents etc. So the concept of Intelligent Traffic System was developed. In this system it was necessary to identify the vehicles that run on the road. So Automatic Number Plate Recognition (ANPR) System was developed. Automatic Number Plate Recognition (ANPR) System is essential in Intelligent Traffic

DILUTIONS AND STANDARDS Many of the laboratory procedures involve the use of dilutions. It is important to understand the concept of dilutions‚ since they are a hand tool used throughout all areas of the clinical laboratory. These dilutions have to be considered as they make a quantitative difference in what is going on. First‚ there are several terms used in expressing dilution: 1. "Dilution: - Dilutions are expressed as the ratio of the quantity of a desired solute (serum‚ urine‚ chemical solution

CONCENTRATION AND DILUTION Physiology 1‚ Las Positas College Name: In science‚ concentration is a measure of the number of particles (solutes) in a given volume. If one room has 100 people in it‚ and a room of equal size has 50 people‚ one can say that the concentration of people in one room is twice that of the other. Quite simple‚ isn’t it? On a molecular level‚ consider whether you put one lump or two of sugar‚ or no sugar at all‚ in your coffee. If you use two lumps‚ you prefer twice
