Bunsen burner
Striker
ignite a Bunsen burner
Utility clampTo secure lab equipment to the
ring stand
Thermometer

Hotplate
Heating chemicals without using an open flame
Heating with burner1. Flame should be 2-3 inches high,
blue with a lighter blue inner cone2. Tip of flame should be 1-2 inches
below wire gauze3. 2nd iron ring to stabilize beakers
Water bath1. Heats the test tube evenly2. Can be done with hotplate or burner3. Water level in beaker should be
higher than the water level in test tube
4. Utility clamp used to stabilize test tube
Cooling hot equipment
1. Hot glass – use insulating pad and leave on lab bench until it is cool enough to touch, then run it under warm water, wipe dry with paper towel
2. Hot metal – pick up cool part and run hot part under cool water, wipe dry with paper towel
Wearing gogglesGoggles should already be on and covering eyes (not forehead or neck) before you walk past the sink & dryrack in the back of the room!
