Electronic Balance

Important:

Easily broken by placing too much mass on the pan

Use: to mass less than 200 grams of a substance


Material: metal with porcelain top

Hot Plate

Use: to heat substances when a burner is not necessary or safe. Sometimes may have a magnetic stirrer as well.


Safety Goggles

Material: plastic, splash resistant

Use: to be worn at all times during labs in which chemicals, heat or glassware is used.


Filter Paper

Material: paper circles, various sizes

Use: folded in quarters, used in funnels to filter solutions


Mortar and Pestle

Material: porcelain

Use: to grind crystals and lumpy chemicals to a powder


Weighing Trays or Weigh Boats

Material: Flexible plastic in various sizes

Use: to keep chemicals off the balance pan.


Scoopula

Material: Metal or metal with wood handle

Use: to transfer solid chemicals


Thermometer

Important:

Never use as a stirring rod

Material: alcohol (red) or mercury in glass (not likely), common range -10°C to 110°C

Use: to measure temperature


Pipet

Important:

Never pipet by mouth

Material: glass or plastic, graduated, various sizes

Use: to measure solution volumes, less accurate than a volumetric pipet


Pipet Safety Bulb

Important:

Never pipet by mouth

Material: rubber

Use: to fill a pipet with solution


Stirring Rod

Material: solid glass or plastic

Use: to stir solutions



Crucible and cover

Important:

Use tongs with hot crucibles

Material: porcelain

Use: to heat small amounts of solid substance at high temperatures


Crucible tongs

Important:

beware of hot porcelain or glassware

Material: iron, nickel or brass

Use: to pick up and hold small usually very hot items


Clay triangle

Material: wire frame with porcelain supports

Use: used to support a crucible


Transfer Pipet

Material: plastic

Use: to dispense and transfer small volumes of solution


Beral pipet - thin stem

Material: plastic

Use: to dispense and store small quantities of solution


24-well spot plate

Material: plastic, may have cover

Use: reaction vessels for small quantities of solution


96-well spot plate

Material: plastic

Use: in place of test tubes in microchemistry


Bunsen burner and burner tubing

Material: metal, connected to gas supply with burner tubing

Use: to heat chemicals (dry or in solution) in beakers, test tubes, flasks and crucibles


Striker

Material: metal with flint

Use: to create a spark to light gas burners


Wire gauze or wire mesh

Material: metal mesh, may have ceramic center

Use: to spread the heat of a burner flame


Watch glass

Material: glass

Use: to cover an evaporating dish or beaker


Test tube clamp or test tube holder

Material: metal spring mechanism

Use: to hold test tubes or glass tubing


Test tube

Important:

Beware of hot glass. Use a test tube holder when heating. Never point a test tube at yourself or other when heating.

Material: glass, various sizes

Use: reaction vessel, may be heated


Test tube rack

Material: wood, plastic or metal

Use: holds test tubes in a vertical position


Test tube brush

Material: bristle with wire handle, various sizes

Use: to scrub small diameter glassware


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


Ring clamp and clamp holder

Material: metal

Use: as a support on a ring stand



Funnel

Material: glass or plastic

Use: Hold filter paper for filtering solutions


Wash bottle

Material: flexible plastic

Use: hold vertically and squeeze sides to dispense water, typically deionized water only


Graduated cylinder or graduate

Important:

Never heat

Material: glass or plastic, various sizes

Use: to measure approximate volumes


Erlenmeyer flask

Material: glass, various sizes

Use: may be heated, useful for swirling solutions, used in traditional titrations


Volumetric flask

Material: glass or plastic, various sizes

Use: for making and storing solution. The score on the neck indicates an accurate volume.


Beaker

Important:

Beware of hot glass, use tongs

Material: glass or plastic, various sizes

Use: for holding solutions or dry chemicals, not for measuring, only gives approximate volume


Beaker tongs

Material: metal with or without rubber coated tips

Use: to move hot beakers and glassware


Evaporating dish

Material: porcelain

Use: to contain small volumes of liquid being heated or evaporated. May be heated.


Ring Stand

Glass or plastic with stopper and stopcock

Used to separate solutions of different phases

Separatory Funnel

Metal rod fixed upright in a heavy metal base

Used to support a variety of clamps


Material: glass with stopcock,graduated,VERY EXPENSIVE

Use: to measure volumes of solution in titrations

Buret

Doubleburet clamp

Material: metal or plastic

Use: to support burets on a ring stand

Stopcock
