  • Bunsen Burner Safety
    Proper Use of a Bunsen Burner If using a Bunsen burner in a biological safety cabinet, see: http://research.wayne.edu/oehs/pdf/gas-in-bsc.pdf Prior to Lighting Bunsen Burner: • Know the location of the laboratory’s main gas shut off valve and fire extinguisher. • Place the Bunsen burner away from any overhead shelving, equipment, or light fixtures by at least 12 inches. • Remove all papers, notebooks, combustible materials, and excess chemicals from the area. • Tie-back any long hair, dangling jewelry, or loose clothing. • Use correct tubing (butyl rubber hose). Inspect hose for cracks, holes, pinch points, or any defect and replace if necessary. Ensure that the hose fits securely on the gas valve and the burner. • Notify others in the lab that the burner will be in use. Lighting Bunsen Burner: • Before turning on gas, have a sparker/lighter with extended nozzle to ignite burner. Never use matches. • Check connections to burner and desk outlet valve. • Close needle valve and collar. • Open gas valve fully. • Open needle valve 1/2 turn. • Use the spark/lighter to light the flame. • Adjust flame by turning the collar to regulate air flow and produce an appropriate flame for the experiment (typically a medium blue flame). During Use: • Never leave a lighted burner unattended. Drafts (including those created by a hood) may extinguish the flame, but the gas will still be on. This could result in an explosion. • Never face the vessel (test tube, beaker, etc.) being used to heat a material toward yourself or others near the burner. In some experiments, a hot plate may be used in place of the Bunsen burner.

  • SF#11086 Sterilization and Aseptic Technique
    Publication No. 11086 Sterilization and Aseptic Technique Introduction Microbiology lab activities are common in middle school and high school life science courses. Learning basic microbiology lab techniques and procedures is interesting and relevant to most students—many of them, after all, have had at least one throat culture or other microbiology lab test in their lives. The requirements for safe microbiological work in the classroom include the knowledge and practice of aseptic technique and sterilization procedures. Standard Microbiology Practices The federal government has outlined general safety standards for microbiological work in their publication Biosafety in Microbiological and Biomedical Laboratories. Biosafety Level I (BSL 1) practices described in this book are appropriate for secondary educational teaching laboratories. BSL 1 work involves using strains of viable, nonpathogenic microorganisms that are known not to cause disease in healthy adult humans and are thus of minimal potential hazard to students, teachers or the environ- ment. The level of containment in BSL 1 relies on standard microbiological practices in laboratory settings. Students and lab per- sonnel should receive specific training in the procedures conducted in the laboratory. Standard microbiological practices include: • Wash hands thoroughly with soap and water before and after handling viable materials, after performing microbiological transfers and observations or working with potentially hazardous materials, and before leaving the laboratory. • Eating, drinking, smoking, handling of contact lenses, applying cosmetics, and storing food for human use are not permit- ted in laboratory work areas. • Pipetting by mouth is prohibited—use only mechanical pipetting devices. • There should be policies and procedures for safe disposal of sharps, including broken glassware.

  • 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.
