1 Laboratory Equipment and its Usage

2 Safety Glasses and goggles: Use to protect your eyes
Safety Glasses and goggles: Use to protect your eyes. MUST be worn at ALL times in the lab ONLY taken off when instructed!!!!!!!

3 Electronic Balance: Used to measure the mass of a solid. NOTE: 1
Electronic Balance: Used to measure the mass of a solid. NOTE: 1. NEVER mass a solid chemical directly on the pan. ALWAYS use weighting paper. 2. ONLY mass solids you are instructed to mass. 3. DO NOT move. 4. $483

4 Beaker: Used to mix and heat solutions and mixtures
Beaker: Used to mix and heat solutions and mixtures. It is graduated but is only used for general volumes measurements. Can use with a stirring rod to pour. MUST marked with Pyrex, TEKK or Bomex to be heated.

5 Erlenmeyer Flask: Used to heat and mix solutions and mixtures
Erlenmeyer Flask: Used to heat and mix solutions and mixtures. It is graduated but is only used for general volume measurements.

6 Graduated Cylinders: Used for measure accurate volumes
Graduated Cylinders: Used for measure accurate volumes Volumes are measured at eye level and looking at the meniscus.

7 Funnel: Used to direct flow to transfer liquids from one vessel to another. Funnels are also used in the process called filtration that separate solids from liquids. NOTE: the funnels are plastic and will melt with heat.

8 Test tubes: Used to heat and mix solutions
Test tubes: Used to heat and mix solutions. MUST be tempered glass (Pyrex, TEKK, Bomax, Kimax) to be used in the lab!!!!!!! Test Tube Rack: Used to hold test tubes. Test Tube Clamp: holds test tube while heating

9 Bunsen Burner: Used to heat solutions. outer cone: 600oF
Bunsen Burner: Used to heat solutions outer cone: 600oF middle cone: HOTTEST oF inner cone: 800oF

10 Flint Spark Lighter: Used to light the Bunsen burner

11 Evaporating Dish: Used to heat solids and drive off any moisture.

12 Ring Stand and Ring: Used to support equipment while heating in the lab. Wire Glaze: supports a beaker and spreads the flame evenly. Funnels Clay Triangle: Used to support a crucible

13 Crucible with lid: Used to heat a solid to a very high temperature.

14 Watch Glass: Used to cover the crucible so that you can ‘watch’ the solid. MUST be Pyrex

15 Stirring Rod: Used to stir a solution and to direct flow of a liquid.

16 Wash Bottle: Used to rinse out solid that may stick to the side of the beaker when a precipitate forms between two solutions.

17 Well Plates: Used to mix solutions

18 Thermometer: Used to measure the temperature of a solution or mixture.

19 Dropper Pipets: Used to transfer small volumes of a liquid.

20 Hot Mitts: Used to handle hot glassware
Hot Mitts: Used to handle hot glassware. Remember hot glass and cool glass look alike.

21 Water Bath Set-up: Used to heat or raise the temperature of a substance to the temperature of water.

22 Titration Set-up: Used in a titration
Titration Set-up: Used in a titration. A titration is a procedure used to determine the concentration of a solution, usually an acid or base.

23 Filtration Set-up: Used to separate a liquid from a solid
Filtration Set-up: Used to separate a liquid from a solid. Place the tip of the funnel along the edge of the beaker to prevent splashing.
