Lab Equipment Erlenmeyer Flask
Lab Equipment Erlenmeyer Flask • Erlenmeyer flasks hold solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated. Beaker • Beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated. Graduated Cylinder • A graduated cylinder is used to measure volumes of liquids. Test Tubes • Test tubes are used to hold small amounts of liquid and to conduct small chemical reactions in. Test Tube Clamp • A test tube holder is useful for holding a test tube which is too hot to handle. Test tube and beaker Brushes • Test tube brushes are used to clean test tubes and graduated cylinders. • Forcing a large brush into a small test tube will often break the tube. Test Tube Racks • Test tube racks are for holding and organizing test tubes on the laboratory counter. Plastic racks may melt in contact with very hot test tubes. Spot Plates • Spot plates are used when we want to perform many small scale reactions at one time. We will use these many times during the year. Watch Glass • A watch glass is used to hold a small amount of solid, such as the product of a reaction. Glass Stir Rod • A glass rod is used to manually stir solutions. It can also be used to transfer a single drop of a solution. Funnel • A funnel is used to aid in the transfer of liquid from one vessel to another. • A funnel is used to separate a solid from a liquid Wash Bottle • A wash bottle has a spout that delivers a wash solution to a specific area. -
Standard Operating Procedures
Standard Operating Procedures 1 Standard Operating Procedures OVERVIEW In the following laboratory exercises you will be introduced to some of the glassware and tech- niques used by chemists to isolate components from natural or synthetic mixtures and to purify the individual compounds and characterize them by determining some of their physical proper- ties. While working collaboratively with your group members you will become acquainted with: a) Volumetric glassware b) Liquid-liquid extraction apparatus c) Distillation apparatus OBJECTIVES After finishing these sessions and reporting your results to your mentor, you should be able to: • Prepare solutions of exact concentrations • Separate liquid-liquid mixtures • Purify compounds by recrystallization • Separate mixtures by simple and fractional distillation 2 EXPERIMENT 1 Glassware Calibration, Primary and Secondary Standards, and Manual Titrations PART 1. Volumetric Glassware Calibration Volumetric glassware is used to either contain or deliver liquids at a specified temperature. Glassware manufacturers indicate this by inscribing on the volumetric ware the initials TC (to contain) or TD (to deliver) along with the calibration temperature, which is usually 20°C1. Volumetric glassware must be scrupulously clean before use. The presence of streaks or droplets is an indication of the presence of a grease film. To eliminate grease from glassware, scrub with detergent solution, rinse with tap water, and finally rinse with a small portion of distilled water. Volumetric flasks (TC) A volumetric flask has a large round bottom with only one graduation mark positioned on the long narrow neck. Graduation Mark Stopper The position of the mark facilitates the accurate and precise reading of the meniscus. If the flask is used to prepare a solution starting with a solid compound, add small amounts of sol- vent until the entire solid dissolves. -
