hi,
here are some proposition to you
rotavapor :
http://media.treehugger.com/assets/images/2011/10/chemistry20lab-jj-001.jpg its use to remove solvants under reduced pressure. so you need : water bath (to heat) condenser (to condence
) and a vacuum pump (to decrease the pressure) and a cooling system for the condenser.
various bottle of solvents(methylene chloride, diethyl ether, pentane, THF, toluene, ...) and reagent (acetyl chloride, pyridine, palladium acetate, benzyl bromide, ...) could be good with pictogram maybe (corrosive, danger, ...)
soxhlet extractor :
http://ainstrumental.wikispaces.com/file/view/SOXHLE~1.JPG/149458865/SOXHLE~1.JPG its used to extract useful molecul from a solid matrix (wood, plants, ...). here an other :

column chromatography :
http://www.wfu.edu/chem/courses/organic/CC/images/column.jpg its used to separe molecules from a complexe mixture. sometime, you can see coloured disk eluting. its just a tube filled with silica gel and solvant and wit a manifold at the end.
boiler + flask + condenser :
http://physique-chimie.gjn.cz/plugins/fckeditor-spip-2/userfiles/3C%20montage%20reflux%20mal%20refroidi.jpg a typical assembly in laboratory. a flask heated and a condenser.
distillation :
http://physiquechimieaulycee.wifeo.com/images/distillation.JPG a typical fractionnal distillation. used to separe volatiles molecules.
in my opinions, people who think about "chemistry lab" want to see many pipes and glassware interconected with white smoke (dry ice), coloured flask (erlenmeyer, beeker, round bottomed flask, ...) and some bottles of chemicals.
hope it will help you
thanks
