Utility clampTo secure lab equipment to the

ring stand

Thermometer

Measure temperature

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!
