Chemistry Laboratory Safety Rules
Orange Coast College Chemistry Laboratory Safety Rules All chemistry students must successfully pass a test on the following material before they are allowed to work in the laboratory. The test consists of 20 multiple choice questions. The importance of safety requires a high passing score. General Rules 1. No eating, drinking, chewing gum, smoking, or vaping is permitted in the laboratory. 2. Shoes (closed-toed) and appropriate clothing must be worn in the laboratory. Sandals, shorts, etc. do not provide sufficient protection from an accident. To prevent damage, avoid wearing expensive clothing in the lab. 3. Be prepared for lab. Read the procedures carefully before your scheduled lab period and follow all instructions. 4. No unauthorized experiments or unsupervised laboratory work is permitted. An unauthorized experiment is anything that is not in the experimental procedures or instructions given by your professor. 5. Visitors and children are not allowed in the laboratory. Exit the lab if you need to communicate with your visitors. 6. Clean up all chemical spills immediately, including water on the floor. 7. Report any accident, no matter how minor, to the instructor. 8. Never leave your experiment unattended when there is a hazard such as a lit burner. 9. Before you leave the laboratory, always clean your work area, lock your drawer, make certain that water and gas are off, and counters and floor are clean and dry. Safety goggles are to be removed only immediately before leaving lab. 10. Keep backpacks & personal items on the coat rack or shelves above them, to keep the aisles free of tripping hazards. -

Laboratory Equipment Used in Filtration
KNOW YOUR LAB EQUIPMENTS Test tube A test tube, also known as a sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top and closed at the bottom. Beakers Beakers are used as containers. They are available in a variety of sizes. Although they often possess volume markings, these are only rough estimates of the liquid volume. The markings are not necessarily accurate. Erlenmeyer flask Erlenmeyer flasks are often used as reaction vessels, particularly in titrations. As with beakers, the volume markings should not be considered accurate. Volumetric flask Volumetric flasks are used to measure and store solutions with a high degree of accuracy. These flasks generally possess a marking near the top that indicates the level at which the volume of the liquid is equal to the volume written on the outside of the flask. These devices are often used when solutions containing dissolved solids of known concentration are needed. Graduated cylinder Graduated cylinders are used to transfer liquids with a moderate degree of accuracy. Pipette Pipettes are used for transferring liquids with a fixed volume and quantity of liquid must be known to a high degree of accuracy. Graduated pipette These Pipettes are calibrated in the factory to release the desired quantity of liquid. Disposable pipette Disposable transfer. These Pipettes are made of plastic and are useful for transferring liquids dropwise. Burette Burettes are devices used typically in analytical, quantitative chemistry applications for measuring liquid solution. Differing from a pipette since the sample quantity delivered is changeable, graduated Burettes are used heavily in titration experiments. -
Whitall Tatum – Part I – Whitall Tatum & Co
Whitall Tatum – Part I – Whitall Tatum & Co. Bill Lockhart, Pete Schulz, Beau Schriever, Bill Lindsey, Carol Serr, and Bob Brown The history of the Whitall Tatum firms may be divided into four sections: The early companies, Whitall Tatum & Co., Whitall Tatum Co., and the factories after the sale to the Armstrong Cork Co. (and later to the Kerr Glass Mfg. Co.). Since we have discovered no glass manufacturer’s marks for the early firms, we have included a brief history of those houses in Part I with Whitall Tatum & Co. Part II is comprised of the history and marks of the second major division, the Whitall Tatum Co. See the Armstrong Cork and Kerr Glass sections for more information on those glass houses both before and after their respective acquisitions of the Whitall Tatum plants. One of the best-known manufacturers of prescription glassware was Whitall Tatum & Co. Once perhaps the largest manufacturer of flint container glass in the world, the firm produced a huge variety of bottles and jars over a long time span. In addition, most Whitall Tatum bottles were clearly marked with the company initials in a variety of styles from the last third of the 19th century until near the end of the 20th century. [This study was originally published as Lockhart et al. 2006, but much of it – especially the history and fruit jar sections – has been greatly expanded.] Histories Whitall Tatum & Co. had a long and involved history that went back to the cylinder window-glass house of James Lee, established in Millville, New Jersey, in 1806. -
Chemistry 2A Lab Manual Standard Operating Procedures Winter Quarter 2018
Chemistry 2A Lab Manual Standard Operating Procedures Winter Quarter 2018 Department of Chemistry University of California - Davis Davis, CA 95616 Student Name Locker # Laboratory Information Teaching Assistant’s Name Laboratory Section Number Laboratory Room Number Dispensary Room Number 1060 Sciences Lab Building Location of Safety Equipment Nearest to Your Laboratory Safety Shower Eye Wash Fountain Fire Extinguisher Fire Alarm Safety Chemicals Revision Date 12/1/2017 Preface Chemistry is an experimental science. Thus, it is important that students of chemistry do experiments in the laboratory to more fully understand that the theories they study in lecture and in their textbook are developed from the critical evaluation of experimental data. The laboratory can also aid the student in the study of the science by clearly illustrating the principles and concepts involved. Finally, laboratory experimentation allows students the opportunity to develop techniques and other manipulative skills that students of science must master. The faculty of the Chemistry Department at UC Davis clearly understands the importance of laboratory work in the study of chemistry. The Department is committed to this component of your education and hopes that you will take full advantage of this opportunity to explore the science of chemistry. A unique aspect of this laboratory program is that a concerted effort has been made to use environmentally less toxic or non-toxic materials in these experiments. This was not only done to protect students but also to lessen the impact of this program upon the environment. This commitment to the environment has presented an enormous challenge, as many traditional experiments could not be used due to the negative impact of the chemicals involved. -

Laboratory Procedure Manual
Laboratory Procedure Manual Analyte: Triglycerides \ Matrix: Serum Method: Roche/Hitachi Modular P Chemistry Analyzer as performed by: Collaborative Studies Clinical Laboratory University of Minnesota Medical Center Fairview-University Medical Center University Campus Minneapolis, Minnesota Contact: Dr. Jack Eckfeldt., M.D. Important Information for Users The Fairview -University Medical Center periodically refines these laboratory methods. It is the responsibility of the user to contact the person listed on the title page of each write-up before using the analytical method to find out whether any changes have been made and what revisions, if any, have been incorporated. Triglyceride in Serum NHANES 2011-2012 Public Release Data Set Information This document details the Lab Protocol for testing the items listed. Data File Name Variable Name SAS Label (and SI units) TRIGLY_G LBXTR Triglycerides(mg/dL) LBDTRSI Triglycerides(mmol/L) Triglyceride in Serum NHANES 2011-2012 1. SUMMARY OF TEST PRINCIPLE AND CLINICAL RELEVANCE A. Clinical Relevance Triglycerides are fatty acid esters of glycerol that have three hydroxyl groups. Because they are insoluble in water, the triglycerides are transported with other more polar lipids. Elevated triglyceride measurements are associated with diabetes mellitus, pancreatitis, alcoholism, glycogen storage disease, hypothyroidism, nephrosis, pregnancy, use of oral contraceptives and gout. Triglyceride levels are decreased in hyperthyroidism, use of certain lipid-lowering drugs and malabsorption syndrome. B. Principle In this enzymatic method reagent 1 (glycerol blanking) is added first. Free glycerol is converted to glycerol-3-phosphate (G3P) by glycerol kinase. G3P is acted upon by glycerol phosphate oxidase to produce dihydroxyacetone phosphate and hydrogen peroxide. The hydrogen peroxide combines with 4- chlorophenol under the action of peroxidase to produce an oxidation product that that does not react with the colorometric component of reagent 2.
