Work Specific Skills Work specific skills focusing on the use of standard operating procedures for different types of laboratory equipment‚ the calibration of standard laboratory equipment and the use of a lab book. This was chosen as a priority for me due to these skills being an essential part of any work I wish to do in the future‚ working or continuing my studies with in a lab. This set of skills is relevant to my skills matrix because it is a skill I have only had the chance to develop at

The total protein content was estimated as proposed by Lowry et al. A bovine serum albumin stock solution (1mg/ml) was prepared in sodium hydroxide (1N). Five different concentrations (0.2‚ 0.4‚ 0.6‚ 0.8‚ 1 ml) of the prepared solution were taken in different test tubes. In another set of test tubes‚ 0.1 and 0.2 ml of the extract were taken. In each test tube‚ the volume was made up to 1 ml‚ followed by addition of the prepared alkaline solution (5 ml) at room temperature. The solutions were left

determine the accuracy of the copper and zinc composition percentages in a random sampling of pennies. The penny was dissolved to make aqueous copper ions and four copper dilutions were made from stock solution. Each cuvette sample was measured in a colorimeter and the data was plotted linearly using Beer’s law plot. Mass percent and percent error were found using calculations. Analysis of class data provided further data to determine the copper and zinc composition percentages. Experimental Procedure

Procedure: Mix 10 mL of sodium hydroxide and crystal violet solution together. After calibrating the colorimeter‚ insert the mixture. Absorbance data will be collected for three minutes. Analyze the data graphically to determine the reaction. Discussion: The hypothesis that I stated was sadly‚ not supported by the data that my partner and I obtained. Comparing
