7. Graduated Cylinder
A graduated cylinder is used to measure accurate volumes of liquids
probably your best everyday measuring tool

8. Test Tubes we commonly use 2 sizes:
18 x 150 mm
Ignition
Tube
(25 x 200 mm)
13 x 100 mm
Test tubes are used to mix chemicals and also to heat chemicals

9. Test Tube Brushes

10. Test Tube Racks
Test tube racks are for holding and organizing test tubes on the laboratory counter

11. Watch Glass
A watch glass is used to hold a small amount of solid, such as the product of a reaction
Can also be used as a cover for an evaporating dish or beaker

12. Stirring Rod The stirring rod is used to: a) manually stir solutions
b) assist in pouring liquids
c) to transfer a single drop of a solution.
Rubber policeman tip is used to remove precipitates

Stir with this end

13. Dropper Pipette
A dropper pipette is used to transfer a small volume of liquid, usually one drop at a time
– never put your mouth on the dropper to provide suction

14. Graduated Pipette
A graduated pipette measures and delivers exact volumes of liquids – uses a rubber bulb for suction

15. Forceps are used to hold or pick up small objects

16. Funnel
A funnel is used to transfer liquid or fine-grained substances into containers with small opening

17. Used where accurate amount of liquid must be added in a small amount
Burettes
