graduated cylinder (graduate) • To measure volume of liquids accurately
SI Ruler (“Metric” is slang. ) • To measure the lengths of solid objects accurately
SI thermometer • To measure temperature accurately
Rubber Stoppers • Chemists use rubber stoppers to contain liquids in flasks and keep contaminants out. • Chemists frequently use rubber stoppers in their labs to plug flasks and test tubes. The purpose of these stoppers is to prevent liquids from escaping their containers
Bunsen burner • To heat substances (with a flame)
hot plate • To heat substances using electricity, not a flame.
ring stand with clamp and ring • To hold containers away from a heat source (such as fire) during an experiment
test tube • To hold liquids and chemicals during experiments (investigations)
test tube holder • To hold test tubes over heat or away from your body
medicine dropper (eyedropper) • To drop small amount of liquids
forceps • To pick up small items that you should not touch
Microscope • To view specimens that are too small to see with the naked eye • Important in the discovery of a cell’s nucleus • If you observe an object at 4 X, then move the objective to 100 X, what happens to the image?
slide • To hold a specimen (sample) for viewing through a microscope
cover slip • To cover a specimen (or sample) on a slide

tongs • To pick up large objects that you should not touch (e. g. , hot containers, flasks of acids, etc. )
Petri dish • To grow bacteria and other tiny living things
test tube brush • To clean the insides of test tubes after investigations
test tube rack • To hold test tubes during an investigation. (After cleaning, test tubes can be placed upside down to dry. )
