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. -

In Eye(s) • Immediately flush eye(s) using emergency eyewash station for a minimum of 15 minutes. In Laboratory • Assess the scene. If the situation is beyond your capabilities, contact your supervisor. • If safe to do so, turn off any ignition sources if flammable material is present. • Use spill kits to assist in spill containment. • Dispose of waste material with other hazardous waste. Fire • If you hear the Fire Alarm ring continuously evacuate the building immediately. • If you hear the Fire Alarm ring intermittently be alert however evacuation is not necessary. • If Fire Alarm changes from intermittent to continuous evacuate immediately • If you detect a fire, do not attempt to extinguish it yourself unless you are capable and it is safe to do so. Report the injury/incident to your supervisor as soon as possible. ** This is to be used as a quick reference only. For more detailed information, please refer to section 8.0 Emergency Procedures.

Gas Generator Bottle Introduction SCIENTIFIC This Gas Generator Setup Provides an Easy Way to Generate and Collect Gas
Gas Generator Bottle Introduction SCIENTIFIC This gas generator setup provides an easy way to generate and collect gas. Specific instructions are provided for the generation of hydrogen gas using zinc and acid. Concepts • Generation of gases • Water displacement Materials Hydrochloric acid solution, HCl, 3 M Glass plates or Sulfuric acid solution, H2SO4, 3 M Glass tubing Mossy zinc, Zn, 6 g Pneumatic trough Water, tap Rubber tubing Bent glass tubing* Silicone grease packet* Gas collecting bottles or tubes, 3 or 4 Thistle tube* Gas generator bottle* Two-hole rubber stopper* *Materials included. Safety Precautions Hydrochloric acid solution is toxic by ingestion and inhalation and is severely corrosive to skin, eyes and other tissues, as is sulfuric acid solu- tion. Hydrogen gas is a highly flammable gas and a severe fire hazard. Exercise extreme caution when testing the gas and keep the gas generator away from flames. Wear chemical splash goggles, chemical-resistant gloves, and a chemical-resistant apron. This activity requires the use of hazardous components and/or has the potential for hazardous reactions. Please review current Material Safety Data Sheets for additional safety, handling, and disposal information. Procedure 1. Set up the apparatus as shown in the figure to the right. Lubricate the glass tubing and thistle tube with silicone grease before inserting into the stopper. Make sure Thistle tube the water level is above the platform. Prepare bottles for collecting gas by water Two-hole rubber stopper displacement. To do this, fill each gas collecting bottle (or tube) over the brim with tap water, and then cover each with a flat glass plate. -
