Microbiology Sec 147848 November 18‚ 2013 Title of the Experiment: Enterobacteriaceae Identification: The Enterotube II System Learning Objectives: After completing this exercise we were able to inoculate an unknown bacterium that belongs to the Enterobacteriaceae by using technology effectively with a Enterotube II. An Enterotube II is a miniaturized multi-test system for rapid identification of enterbacteriaceae. We then evaluated the test results and generated a five-digit code for the unknown

Chem 105 Guide to the Formal Laboratory Report The purpose of a formal report is to communicate effectively to another person the goal‚ procedure‚ data analysis method‚ and results of your laboratory work. The report is divided into several well-defined sections. Each section must be present in a complete report. To earn an outcome point for the laboratory report‚ a student must submit a formal lab report that earns a score of at least 90/100. Each error (factual‚ grammatical‚ typographical

Recrystallization and Melting Point Determination W. H. Bunnelle‚ L. A. Meyer‚ R. E. Glaser (Version 3) Introduction Consider what happens when a solid material is placed in a solvent in which it has a low solubility. Not much! A small fraction of the solid will dissolve‚ but the rest will just sit there. (Actually‚ it doesn’t just ’sit there’ since an equilibrium is in effect‚ with solid molecules going into solution‚ and an equivalent number of dissolved molecules reforming solid‚ but we

Lab Report - Microbes Aim: To investigate four areas of the school and to find out which of the four have the most microbes. Areas to Sample: 1. Girl’s locker room (Senior school) 2. Girl’s locker room (Elementary school) 3. Boy’s locker room (Senior school) 4. Boy’s locker room (Elementary school) Hypothesis: We predict that the boy’s locker room in the senior school will have the most microbes. First of all‚ there are more people using our locker rooms in the Senior School

Physics 1003 Experiment Report In this experiment‚ the technician began with the demonstration of solar energy. Solar energy is the conversion of light energy to electrical energy by using solar panels. Solar panels are devices that contained solar module which use light energy from light to generate electricity through the photovoltaic effect. And photovoltaic modules generate electricity from a frequency of light. From my observation of the experiment‚ I found that the panel is black in

EXPERIMENT 3: ISENTROPIC EXPANSION PROCESS Objective In order to demonstrate the isentropic expansion process. Introduction Isentropic means no change in entropy. Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. In simple terms‚ the measure of the level of disorder in a closed but changing system‚ a system in which energy can only be transferred in one direction from an ordered state to a disordered

melting point of pure compound is in the range of 169-172 ℃. During lab Paracetamol medication was dissolved in water‚ purified and recrystallized again. The purpose of the experiment was to learn basic recrystallization techniques that include hot and cold filtration. During experimental procedure sample was purified and its final melting point was measured. Procedure 1.0 g of impure Paracetamol was added to the flask with 2 boiling chips. 30 mL of distilled water were poured to the flask and

ENZYME LAB REPORT 1. In your own words‚ define objective qualitative and objective quantitative data. DO NOT USE EXAMPLES AS YOUR SOLE DEFINITION. (3) There are two different types of information that can be obtained from research. The types of information that can be obtained are quantitative and qualitative data. Research results are considered qualitative when the results can be answered with a simple statement of yes or no. Qualitative data does not attempt to give a numerical value; instead
