2 Electronic Balance Use: to mass less than 200 grams of a substance Important: Easily broken by placing too much mass on the pan

3 Hot Plate Use: to heat substances when a burner is not necessary or safe. Sometimes may have a magnetic stirrer as well. Material: metal with porcelain top

4 Safety Goggles Material: plastic, splash resistant Use: to be worn at all times during labs in which chemicals, heat or glassware is used.

5 Filter Paper Material: paper circles, various sizes Use: folded in quarters, used in funnels to filter solutions

6 Mortar and Pestle Material: porcelain Use: to grind crystals and lumpy chemicals to a powder

7 Weighing Trays or Weigh Boats Material: Flexible plastic in various sizes Use: to keep chemicals off the balance pan.

8 Scoopula Material: Metal or metal with wood handle Use: to transfer solid chemicals

9 Thermometer Material: alcohol (red) or mercury in glass (not likely), common range -10°C to 110°C Use: to measure temperature Important: Never use as a stirring rod

10 Pipet Material: glass or plastic, graduated, various sizes Use: to measure solution volumes, less accurate than a volumetric pipet Important: Never pipet by mouth

11 Pipet Safety Bulb Material: rubber Use: to fill a pipet with solution Important: Never pipet by mouth

12 Stirring Rod Material: solid glass or plastic Use: to stir solutions

13 Don’t be confused!

14 Crucible and cover Material: porcelain Use: to heat small amounts of solid substance at high temperatures Important: Use tongs with hot crucibles

15 Crucible tongs Material: iron, nickel or brass Use: to pick up and hold small usually very hot items Important: beware of hot porcelain or glassware

16 Clay triangle Material: wire frame with porcelain supports Use: used to support a crucible

17 Transfer Pipet Material: plastic Use: to dispense and transfer small volumes of solution

18 Beral pipet - thin stem Material: plastic Use: to dispense and store small quantities of solution

19 24-well spot plate Material: plastic, may have cover Use: reaction vessels for small quantities of solution

20 96-well spot plate Material: plastic Use: in place of test tubes in microchemistry

21 Bunsen burner and burner tubing Use: to heat chemicals (dry or in solution) in beakers, test tubes, flasks and crucibles Material: metal, connected to gas supply with burner tubing

22 Striker Material: metal with flint Use: to create a spark to light gas burners

23 Wire gauze or wire mesh Material: metal mesh, may have ceramic center Use: to spread the heat of a burner flame

24 Watch glass Material: glass Use: to cover an evaporating dish or beaker

25 Test tube clamp or test tube holder Material: metal spring mechanism Use: to hold test tubes or glass tubing

26 Test tube Material: glass, various sizes Use: reaction vessel, may be heated Important: Beware of hot glass. Use a test tube holder when heating. Never point a test tube at yourself or other when heating.

27 Test tube rack Material: wood, plastic or metal Use: holds test tubes in a vertical position

28 Test tube brush Material: bristle with wire handle, various sizes Use: to scrub small diameter glassware

29 Utility clamp Material: metal, with or without coated ends Use: to support equipment on a ring stand, this one would need a clamp holder as well

30 Ring clamp and clamp holder Material: metal Use: as a support on a ring stand

31 Ring clamp - one piece

32 Funnel Material: glass or plastic Use: Hold filter paper for filtering solutions

33 Wash bottle Material: flexible plastic Use: hold vertically and squeeze sides to dispense water, typically deionized water only

34 Graduated cylinder or graduate Material: glass or plastic, various sizes Use: to measure approximate volumes Important: Never heat

35 Erlenmeyer flask Material: glass, various sizes Use: may be heated, useful for swirling solutions, used in traditional titrations

36 Volumetric flask Use: for making and storing solution. The score on the neck indicates an accurate volume. Material: glass or plastic, various sizes

37 Beaker Material: glass or plastic, various sizes Use: for holding solutions or dry chemicals, not for measuring, only gives approximate volume Important: Beware of hot glass, use tongs

38 Beaker tongs Material: metal with or without rubber coated tips Use: to move hot beakers and glassware

39 Evaporating dish Material: porcelain Use: to contain small volumes of liquid being heated or evaporated. May be heated.

40 Ring Stand Separatory Funnel Glass or plastic with stopper and stopcock Used to separate solutions of different phases Metal rod fixed upright in a heavy metal base Used to support a variety of clamps

41 Buret Double buret clamp Stopcock Material: glass with stopcock, graduated, VERY EXPENSIVE Use: to measure volumes of solution in titrations Material: metal or plastic Use: to support burets on a ring stand

42 Fleaker
