1. Beaker - For hold solid or liquid will not release gases when reacted.
2. Conical Flask 1. Not accurate liquid-measuring container. 2. For hold solid or liquid may be release gases when reacted.
3. Volumetric flasks 1. to measure precise volumes of liquid 2. to make precise dilutions.
4. Graduated cylinder for measurement of an amount or volumes of liquid. The volume of liquid can be estimated to the nearest 0.1 mL with practice.
5. Graduated pipette or pipette 1. measures solution volumes 2. used to transfer measured substances into another vessel
6. pipette - used to transfer measured substances into another vessel
7. dropper - Used for addition of liquids, drop by drop
8. test tubes - Used for holding small samples or for containing small-scale reactions
9. test-tube holder - Used for holding test tubes when tubes should not be touched
10. funnel - Used to transfer solids and liquids without spilling
11. burette - used for measures volume of solution in titration process
12. ring stand (with rings or clamps) - Used for holding pieces of glassware in place.
13. wash bottles -Used for dispensing small quantities of distilled water.
14. crucible - used to heat a small amount of a solid substance at a very high temperature
15. Balance -Used for measures mass of material
16. Thermometer - Used for measures temperature
17. wire gauze on a ring - - Used for supports beakers to be heated by Bunsen burners
18. watch glasses - Used for holding small samples or for covering beakers or evaporating dishes.
19. Spatulas - Used For dispense solution from their containers
20. Glass Stir Rod - Used for stir solutions
Lab Equipment. Beaker Beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated.
EQUIPMENT ID Bunsen burner – heat source
Materials to use in the Lab By Crystal Schmit. Crucible Tongs These tongs are used to pick up and hold a very hot crucible to prevent from burning yourself.
Lab Equipments. Test Tubes 13 x 100 mm test tubes 10 x 75 mm test tubes Ignition tube Used for chemicals to mix or reaction.
Lab Equipment. Balance Used to mass objects
Lab Equipment. BEAKER Beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated.
