LABORATORY and SAFETY EQUIPMENT AND THEIR FUNCTIONS

Goggles Most important piece of lab equipment Protects eyes from broken glass, chemicals, and flames.

Lab Aprons Protects clothes from chemicals

Eye Wash Rinse eyes for 15-20 min. if exposed to chemicals

Fire Blanket Wrap around a person whose clothes or hair have caught on fire (then they should drop and roll)

Shower If a chemical is spilled over a large part of the body (all over clothes or legs)

Beaker Used to hold or mix chemicals May be heated

Stirring Rod Glass rod used for stirring and helping pour BE CAREFUL! They break easily

Erlenmeyer Flask May be heated Used for mixing chemicals

Volumetric Flask Used to make solutions of specific volume NEVER heated Has calibration line to signify volume

Graduated Cylinder Measures volumes of liquids

Test Tube May be heated Holding small amounts of chemicals For small reactions

More Test Tubes 13 x 100 mm test tubes Ignition tube

Wire Gauze Spreads out the heat produced by a Bunsen burner Can place a beaker on top

Test Tube Holder DUHHHHH It holds a test tube

Test Tube Rack Holds test tubes in a vertical position. Allows for clear sight. Drying rack

Ring Stand Multi-purpose, mostly used as a support to heat chemicals and hold burets.

Ring Clamp One side clamps to ring stand. Place wire gauze on ring and it will hold beakers and flasks for heating. Holds funnels for filtration

Utility Clamp Attaches to ring stand Used to hold flasks and thermometers

Liquid Funnel Holds filter paper for filtering solutions. Transferring liquids to smaller narrow necked containers.

Powder Funnel Transferring solids/powders into flasks and/or beakers. Note the wider spout.

Watch Glass Used as a beaker cover Can be used to place small amounts of chemicals on (looks like a contact lens)

Evaporating Dish Holds small volumes of liquids being evaporated.

Well Plate Used for mixing small amounts of chemicals together

Plastic Wash Bottle Dispenses water for rinsing equipment

Crucible and Lid Holds small amounts of chemicals for heating at high temperatures.

Clay Triangle Supports a crucible in a ring stand apparatus.

Crucible Tongs Pick up and hold small hot items like a crucible. Not for holding glassware

Beaker Tongs Pick up and hold ONLY hot beakers. Has rubber tips

Utility Tongs Pick up and hold flasks or hot metal. Not for holding Beakers!!

Forceps Used to pick up small items.

Bunsen Burner (& Striker) Controls release of natural gas for burning. Tubing connects to gas source. Striker with flint is used to ignite the burner (or matches).

Triple Beam Balance Measures mass in grams Measures to 0.01 place

Rubber Stopper Covers test tube for mixing

Spatula Used to transfer solids from one container to another

Test Tube Brush Cleans out a test tube

Triangular File Triangular files are used primarily to cut glass rod, a skill that your instructor will share with you if it becomes useful.

Thermometer Takes temperature (in Celsius)

Mohr Pipet Used for measuring very small volumes of liquids Needs a bulb to draw fluid into pipet

Rubber Bulb Used to draw liquid into a pipet

Plastic Pipet Used for dropping small amounts of liquid Not accurate for measurements

Buret Used for measuring very small volumes of liquids and dispensing them

Double Buret Clamps Double Buret clamps are used to hold burets used in titration.

Kimwipes Used only for drying glassware Lint-free

Glass Plate Used to cover glassware Also used to put samples onto

Gas Collecting Bottle Used to collect gas during an experiment
