1
Laboratory Equipment Pictures and Descriptions of Chemistry Equipment Used in the Laboratory
2
Beaker Glass or plastic Common sizes are 50 mL, 100 mL, 250 mL, 400 mL, 600 mL Glass beakers can be heated, plastic cannot Beakers are only used for measuring approximate volumes
3
Beaker Tongs Metal with plastic covering Used to pick up hot beakers Should not be held over a flame or the plastic will melt
4
Bunsen Burner Constructed of metal Connected to a gas supply with rubber tubing Used to heat chemicals in beakers, test tubes, and crucibles
5
Clay Triangle Wire frame with porcelain supports It can be used to support a crucible if it is placed on a iron ring
6
Crucible & Cover Porcelain Used to heat small amounts of solid substances at high temperatures
7
Crucible Tongs Iron or Nickel Used to pick up and hold small items (such as crucibles and their lids)
8
Dropper Pipet Glass tip with rubber bulb Used to transfer small volumes of liquid
9
Electronic Balance Used for measuring the mass of chemicals and objects less than 400 grams Chemicals and hot glassware should never be placed directly on the balance
10
Erlenmeyer Flask Glass Common sizes are 50 mL, 125 mL and 250 mL May be heated Can be used as a reaction vessel such as in a titration
11
Evaporating Dish Porcelain Used to contain small volumes of liquid being evaporated
12
Flint Striker Metal with magnesium flint Used to light a Bunsen burner
13
Forceps Metal Used to hold or pick up small objects
14
Four Beam Balance Used for measuring the mass of chemicals and small objects Usually a four beam balance can more accurately find masses than a three beam (platform) balance
15
Funnel Glass or plastic Common size holds 12.5 cm diameter filter paper Can be used for separating mixtures
16
Graduated Cylinder Glass or plastic Common sizes are 10 mL, 50 mL, and 100 mL Used to measure the volume of a liquid Must not be heated and reactions should not be done in the graduated cylinder
17
Grease or Wax Pencil Wax marking pencil Used to write on glassware
18
Mortar and Pestle Porcelain May be used to grind crystals and lumpy chemicals to a powder
19
Nichrome Wire Glass or metal rod with a nichrome wire attached Used for conducting flame tests
20
Petri Dish & Cover Glass top and bottom Used for examining specimens
21
Platform Balance Sometimes also referred to as a triple beam balance Used for measuring the mass of chemicals and small objects
22
Policeman Plastic Used to remove precipitates from glassware
23
Ring Clamp Metal Can be attached to a ring stand to support beakers or other glassware
24
Ring Stand Metal rod fixed upright in a heavy metal base Has many uses as a support
25
Safety Goggles Plastic Must be worn at all times while working in the laboratory
26
Scoopula or Microspatula Metal Used to transfer solid chemicals The scoopula has a larger capacity
27
Stirring Rod Glass rod Used to stir and assist in pouring liquids
28
Test Tubes Glass Common sizes : small (13 mm x 100 mm) medium (20 mm x 150 mm) large (25 mm x 200 mm) May be heated Should not be used if chipped or cracked
29
Test Tube Brush Bristles with wire handle Used to scrub small diameter glassware (like test tubes)
30
Test Tube Clamp Metal Can be attached to a ring stand to hold small diameter glassware
31
Test Tube Holder Spring metal Used to hold test tubes or glass tubing
32
Test Tube Rack Wood or plastic Holds test tubes in a vertical position
33
Triangular File Metal Used to scratch glass tubing prior to breaking to desired length
34
Wash Bottle Flexible plastic Should only be filled with distilled water Used to rinse chemicals from glassware
35
Watch Glass Glass Used to cover an evaporating dish or beaker
36
Wire Gauze Metal with asbestos center Used to spread the heat of a Bunsen burner
37
Utility Tongs Metal Used for picking up hot objects
