Materials and Methods The laboratory procedures were conducted based on the steps provided in ‘An Introduction to Chemical Systems in the Laboratory’1. Specifically‚ 1.90 grams of KCL was weighed in a 250ml beaker and dissolved in 25 ml of deionized water. This solution was then quantitatively transferred to a 250ml volumetric flask. Proper technique is needed for quantitative analysis. This transfer was done to ensure that there was no detectable KCl left in the beaker. After transferring the

with the caffeine. The column now only contains the desired compound caffeine and to extract caffeine from the column‚ a smaller one-armed Erlenmeyer flask that is clean will used to hold this extraction and 5 mL of ethyl acetate will be passed through SPE column‚ to obtain and remove the caffeine from the SPE column. A small one-armed Erlenmeyer flask containing 5 mL of ethyl acetate along with the compound caffeine‚ should be the result after using the SPE column

Biology Laboratory Report Practical 4 Food tests Introduction The main components of food are proteins‚ fats‚ carbohydrates‚ and‚ of course‚ water. Proteins‚ lipids and carbohydrates are carriers about energy necessary for vital activity. They are a plastic material for the formation of structures of the body‚ as well as used for the synthesis of hormones and substances that transmit signals in the nervous system. Our food also includes food (plant) fibers‚ has recently seemed unnecessary ballast

Essay Rough Draft Theranos started out as an epiphanic idea of a Stanford dropout by the name of Elizabeth Holmes. The privately-held medical laboratory service prided itself on its transparency and the innovative ways of collecting and processing lab results so that the patient would spend less money‚ less time‚ and less stress with regards to laboratory results (Topol 2013). Holmes wanted to reshape healthcare‚ promote altruism‚ and make a name for herself‚ but instead has been unable to adequately

On Friday July 15‚ my group of medical student visited the simulation laboratory. After climbing a couple sets of stairs we were broken off into three different groups for three different sets of activities. The first for me a combination of a couple of simulations. The first one was a simulation designed to help surgeons further develop their skills. We used small clamps to pick up and move rings to different poles. This seems quite simple but we had to do it looking at a monitor that projected
