Question

wire gauze
triple beam balance
stirring rod
evaporating dish
tripod
rubber stopper
cork
cork borer
graduated cylinder
test tube
hard glass test tube
glass tubing
rubber tubing
mortar and pestle
bunsen burner
bunsen clamps
clamp holders
beaker
filter paper

Answer 1

My chemistry book had a special chapter regarding the usage of these lab equipments. Don't you have it?

Answer 2

Wire gauze - Used to support larger pieces of glassware/ceramics that are being heated. Used in conjunction with a ring stand.
Triple beam balance - Weighing. More often than not you'll use a more accurate electronic balance.
Stirring rod - Stirring (kinda obvious)
Evaporating dish - Used to evaporate water and/or other solvents away.
Tripod - Stand used for heating.
Rubber stopper - Plug up openings, usually in test tubes or Erlenmeyer flasks
Cork - Can be used to plug up openings, but larger cork rings can be used to support round bottom flasks
Cork borer - Used to drill holes through cork stoppers, to allow the insertion of glass tubing.
Graduated cylinder - Used to precisely measure volumes. Range from 10 ml up to 2-4 L.
Test tube - Usually 10-25 ml, cheap way to view small scale qualitative reactions (really no difference between a normal test tube and a "hard glass" test tube).
Glass tubing - Placed in stoppers, usually to introduce gases without opening the vessel.
Rubber tubing - Used as a connector. Thick-walled rubber tubing can withstand vacuum pressure.
Mortar and pestle - Used to grind solids into fine powders (mortar is the dish, pestle is the "stick").
Bunsen burner - Used to heat. Named after Robert Bunsen, 19th century German chemist
Bunsen clamps - Really is no such thing. There are many different types of clamps. Screw clamps and pinch clamps are used to pinch off rubber tubing, three-pronged clamps or two-pronged clamps hold vessels in place, test-tube clamps hold test tubes to allow for remote handling when heating.
Clamp holders - Are either straight or at right angles to attach clamps to latticework.
Beaker - Range from 10 ml up to 4000 ml, standard open glassware to hold liquids, do weighings, stir reactions in.
Filter paper - Used to filter solids from solutions. Usually used with funnels to allow quick filtering. Come in various sizes and have various pore sizes.

Answer 3

triple beam balance is a scale so it measurse weight in grams, stirring rod= safly mixes chemicals, evap dish = small container in which you heat chemicals to observe the reaction, rubber stopper = seals a test tube or beaker, graduated cylinder = measures and holds, test tube = allows for small amouts of chemicals to be tested, mortar and pestel = grind up "ingresients" to make them smaller/finer, bunsun burners give you flames to heat things with, clamps are so you can hold/move things without burning or hurting yourself, and filter paper = you seperate the solid from the liquid or one chemical from another.

Answer 4

Yep.... A Bunsen burner is used to heat an experimental set-up mildly. It is used instead of a spirit lamp.



Well, I have an comment... It's a very nice question to ask...
