Laboratory Equipment Notes Test tube or bottle brush Beaker Graduated Cylinder Triple beam balance Hand Lens Metric Ruler To find out how tall you are in inches, multiply by .3937 inches per centimeter. Test Tubes and tongs Test tube Rack Safety Goggles Dissecting tray Forceps (tweezers) Scissors Probes Bent probe Needle probe Scalpels Petri dish Beaker Funnel Flask Graduated cylinders Thermometer Cover slip Microscope slides Eyedropper Depression slide Beaker Cup-like container with graduated markings (known scientific measurements)… Flask Modified container that can be used for mixing chemicals. Can also be used for the temporary storage of chemicals. Test tube: Cylindrical glass tube used for conducting experiments. Test tube rack: Holds test tubes securely before, during, and after experiments. Microscope Slide: Thin rectangular piece of glass for a specimen to rest upon while viewing with a microscope. Cover slip: Protective cover placed upon a microscope slide to keep the viewed material stationary. Depression slide: Specialized microscope slide that has a small depression for viewing material too large for traditional slides. Also used for viewing live specimens. Graduated cylinder: Provides accurate measurements of liquids used in the lab in increments as small as 1 milliliter (ml). Test Tube Brush: Used to clean test tubes before and after each lab. Safety Glasses (Goggles): Worn to protect the eyes from flying debris and sprayed fluids during labs. Eye dropper: Allows a controlled dispensing of liquids during experiments. Stirring Rod: Thin piece of glass used in labs for stirring liquids and solids together. Dissecting Tray: Metal tray with a wax bottom upon which a specimen is explored and experimented during labs involving dissection. Probe: Blunt thin tool used during dissection that allows for separation of tissues… without causing excessive damage. Dissecting Needle: Fine-tipped probe used to maneuver parts of a dissection specimen during labs. Forceps: Also known as tweezers, used for grasping parts of a specimen during dissection. Petri Dish: A two part dish commonly used with agar for growing microorganism cultures for study. 18. Microscope: Lab equipment that uses lenses, mirrors, and light to magnify items not seen with the naked eye. Compound Light Microscope: The kind we use in class. Ours can magnify up to 400 times (400X). Scanning Electron Microscope Can magnify up to 100,000 times (100,000 X)! Produces a 3-D image of the surface of the object. Scanning Electron Microscope Bounces electrons off the surface of the specimen. Scans a 3-D image of the outside of the specimen: Black Widow Spider claw (500X) Transmission Electron Microscope Can magnify up to 200,000 times (200,000 X) !! Electrons pass through the specimen. A flat image is produced that shows the specimen’s insides. Transmission Electron Microscope Heart muscle cells seen with a transmission electron microscope at 20,000 X. 19. Thermometer: Measures temperature using the Celcius (ºC) scale. 20. Triple Beam Balance: Measures mass of an object, item, or specimen using counter balances (known masses). Mass is measured in grams (g).
