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.
Florence Flask Rarely used in first year chemistry, it is used for the mixing of chemicals. Narrow neck prevents splash exposure.
Beaker Beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated.
Thermometer The thermometer is used to measure the temperature. In science we use the Celsius measurement.
Test Tubes Students and scientists use test tubes to grow plants, small animals (insects) and other organisms in controlled environment. Chemists used test tubes for chemical reactions, heat reactions, simple distillations, and temporary storage of chemical samples.
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.
Test Tube 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.
Mohr Pipet A Mohr pipet measures and delivers exact volumes of liquids.
Graduated Cylinder A graduated cylinder is used to measure volumes of liquids.
Triple Beam Balance The triple beam balance is used to measure the mass of objects.
Safety Goggles Safety goggles are used to protect your eyes from foreign objects.
Magnifying Glass / Hand Lens The hand lens helps magnify objects so that a scientist may see details that the naked eye could not observe.
Test Tube Holder A test tube holder is useful for holding a test tube which is too hot to handle.
Bunsen Burner Bunsen burners are used for the heating of nonvolatile liquids and solids.
Petri Dish A petri dish is a shallow glass or plastic cylindrical lidded dish that biologists use to culture (grow) cells.
Beaker Tongs Beaker tongs are used to move beakers containing hot liquids
Metric Ruler The metric ruler is used to measure length or distance. In science we use the metric system because the conversions are much easier.
Medicine Dropper A medicine dropper is used to transfer a small volume of liquid (less than one mL). On top of each medicine dropper is a “rubber bulb”
