LAB EQUIPMENT AND THEIR USES 2009| Winkler| AAS
2
INTRODUCTION: You will need to know these items by sight and be able to provide the proper use for each. As a tool to help you study, I have put together a photo collection of the items you will need to know. The equipment reviewed in this PowerPoint will be used for the remainder of the year.
3
GRADUATED CYLINDER Measures liquids (between 1ml-500ml) Measures volume
4
BEAKER Measures liquids (not as accurate as graduated cylinder) container for liquids Used for heating and viewing
5
BEAKER TONGS: Beaker tongs are used to hold and move beakers containing hot liquids.
6
ERLENMEYER FLASKS hold and/or heat solids or liquids that may release gases during a reaction, or that are likely to splatter if stirred.
7
TEST TUBES: Test tubes are used to mix chemicals and also used to heat chemicals in.
8
TEST TUBE RACK: Test tube racks are for holding, drying, and organizing test tubes in a vertical position, and are located in the side wall cabinets.
9
TEST TUBE HOLDER: A test tube holder is useful for holding a test tube which is too hot to handle with your hands.
10
TEST TUBE BRUSH: Test tube brushes are used to clean test tubes and graduated cylinders.
11
FUNNEL: A funnel is used to: 1) aid in the transfer of liquids from one vessel to another, and 2) Hold filter paper while filtering.
12
STOPPER: Rubber and cork stoppers are used to close test tubes and flasks, thus avoiding spillage or contamination.
13
STIRRING ROD: The stirring rod will: a) manually stir solutions; b) assist in pouring liquids; and c) transfer a single drop of a solution to test papers (like litmus)
14
WEIGHING BOATS: Weighing boats are used for holding and determining the mass of solid chemicals. Never put chemicals directly on the balance scale – they will leave a contaminating residue.
15
SCOOPULAS: Scoopulas are used to dispense solid chemicals from their containers.
16
BURNERS: Burners are used for the heating of nonflammable liquids and solids.
17
RING STANDS: Ring stands are a safe and convenient way to support equipment holding reactions that require heating using a lab burner. The base can also be used as an insulating pad to place hot objects on while they cool.
18
RING CLAMPS: Ring clamps connect to a ring stand, and when used with a wire gauze provide a stable, elevated platform for a beaker to rest when heated.
19
TEST TUBE CLAMPS: Test tube clamps are used to secure test tubes to the ring stand.
20
TRIPLE BEAM BALANCE: Used for measuring mass
21
MORTAR AND PESTLE: Used for grinding substances
22
THERMOMETER: Used to measure temperature
23
GOGGLES: Protects your eyes
