Science Lab Equipment Identification Lab Safety Goggles • Goggles or safety glasses are a form of protective eyewear that usually enclose the eye area to prevent particulates or chemicals from striking the eyes. They are used in chemistry laboratories and in woodworking METERSTICK MEASURES THE DISTANCE BETWEEN 2 POINTS EXAMPLES: LENGTH, WIDTH, HEIGHT, DEPTH Units include meter, centimeter and millimeter Graduated Cylinder • A graduated cylinder measures the volume of liquids in a quantitative manner in units called milliliters. Triple Beam Balance • A triple beam balance is used to accurately measure the mass of an object. The object is balanced when the pointer is at zero. The unit of mass is the gram . Spring Scale (spring balance) Measures the weight of an object in Newtons (N) Thermometer • A thermometer is a device used to measure temperature. In the science class, temperature is measured in degrees Celsius. Test Tube • A test tube is a kind of laboratory glassware Test tubes allows you to heating small samples and are made of Pyrex. Beaker • A beaker is a type of laboratory glassware that is very stable and easy to handle. It gives a rough estimation of liquid volume. Erlenmeyer Flask • An Erlenmeyer flask is a type of glassware with a triangular base. The neck opening is smaller than a beaker and slows down evaporative loss better. eye dropper or Dropper Pipette Used to mix or dispense small amounts of liquid, one drop at a time. Funnel • A funnel is a device to channel liquid or finegrained substances into a second container with a smaller opening Hot Plate • A hot plate is a small electric stove often used to heat glassware. Test Tube Rack Used to store and hold test tubes in an upright position. Test Tube Brush Used to clean the inside of test tubes. Stirring rod To mix solutions use a stirring rod NOT a thermometer SPALUTA To remove a small amount of a chemical from a bottle use a spatula Micro-plate Used in chemistry to mix and test small amounts of chemicals Evaporation dish a small vessel with a wide opening used for rapid evaporating, weighing small quantities of powder and burning chemicals Tongs Tongs are gripping and lifting tools. The tips are adapted depending on their specific use. Stopwatch Used to time events in seconds Forceps (also known as tweezers) • Forceps are a hand-held instrument for grasping and holding objects, similar in concept to tongs, tweezers or pincers.
