Laboratory tools

  1. 1. Laboratory Tools <ul><li>Laboratory tools are used to make measurements and gather data in lab. Knowing how to use these tools is important for making precise and accurate measurements. Some common laboratory tools are shown below. </li></ul>
  2. 2. Triple Beam Balance A triple beam balance is used to measure the mass of solid objects. It has three beams that each measure mass to a different unit place (ones, tens, hundreds). Units of mass include milligrams, grams, and kilograms.
  3. 3. Graduated Cylinder <ul><li>A graduated cylinder is used to measure the volume of liquids in milliliters (mL). A graduated cylinder is read by looking at the very bottom of the curve of liquid in the cylinder. This curve of liquid is called a  meniscus . </li></ul>
  4. 4. Test Tube A test tube is a long, narrow type of glassware in which liquids can be stored and heated. Test tubes have round bases and are stored in test tube racks or mounted on test tube stands.
  5. 5. Beaker A beaker is a type of glassware. It can be used to store liquids, heat liquids, and measure the volumes of liquids. Beakers have broad, flat bases. Beakers usually measure liquid volumes in milliliters (mL).
  6. 6. Measuring Cup <ul><li>A measuring cup is used to measure the volume, or amount, of a liquid. To measure how much liquid is in a measuring cup, use the lines marked on the front of the cup. Measuring cups can measure volume in metric units, such as milliliters (mL), or in U.S. system units, such as ounces and cups. </li></ul>
  7. 7. Ruler, Meter Stick, and Tape Measure <ul><li>Rulers, meter sticks, and tape measures are used to measure length. These tools usually have two edges—one that measures in metric units (millimeters, centimeters, and meters), and one that measures in English units (inches and feet). </li></ul>
  8. 8. Spring Scale <ul><li>A spring scale is used to measure the weight, or gravitational force, of an object. It is used by attaching an object to the hook at the end of the scale, then the weight is displayed on the tube of the scale in Newtons (N) or pounds (lb). </li></ul>
  9. 9. Compass <ul><li>A compass is a tool that detects magnetic fields. When no local fields are present, a compass will detect Earth's magnetic field. The arrow of a compass generally points North, so a person using a compass can tell which direction (North, South, East, or West) he or she is facing. </li></ul>
  10. 10. Microscope <ul><li>A microscope is used to view objects, such as cells, that are too small to be seen with the naked eye. </li></ul>
  11. 11. Binoculars <ul><li>Binoculars are used for seeing objects that are distant, but not as far away as outer space. </li></ul>
  12. 12. Hand Lens <ul><li>A hand lens is used to look at objects up close. It makes objects appear larger. </li></ul>
  13. 13. Telescope <ul><li>A telescope is used to view objects, such as planets and moons, that are very far away. </li></ul>
  14. 14. Stopwatch <ul><li>A stopwatch is used to measure time in seconds and minutes. </li></ul>
  15. 15. Thermometer <ul><li>A thermometer is used to measure temperature in either °C or °F. A thermometer is read by looking at the number that is displayed at the top of the red line inside of the thermometer. </li></ul>
  16. 16. Hot Plate <ul><li>A hot plate is a type of lab equipment used to heat substances (usually liquids). It has a flat platform where a beaker containing a liquid can be placed. </li></ul>
  17. 17. Funnel <ul><li>A funnel is a cone-shaped pipe that is open at both ends. Funnels make it easy to pour liquids from a large container into a narrow container. </li></ul>
  18. 18. Magnet <ul><li>A magnet can be used to test for magnetic properties in minerals. It can also be used to separate things containing iron metal from things that do not contain iron. </li></ul>
