8. Measuring tools Testing tools Magnifying tools

9. Glass and Porcelain Equipment

10. Used to measure the volume of liquids Graduated Cylinder

11. Used as a container when measuring approximate volume of liquids Beaker

12. Graduated flask used in volumetric analysis Florence Flask

13. Erlenmeyer flasks are suitable for heating liquids, e.g. with a Bunsen burner . Erlenmeyer flask

14. Used in determining the temperature of a substance thermometer

15. These are widely used by chemists to hold, mix, or heat small quantities of solid or liquid chemicals, especially for qualitative experiments and assays. Test tube

16. A meter stick is a measuring tool used for measuring the length of objects using the metric scale. METER STICK

17. Used in filtration and in transferring liquid funnel

18. Used as a container when observing the reaction of a substance when exposed to air Watch glass

19. Used in mixing solutions; directs the flow of liquids Stirring rod

20. Used in glass connections, preparation of medicine dropper, glass jets, etc. Glass tube

21. Used to transfer and measure small amounts of liquid Medicine dropper

22. Container for evaporation Evaporating dish

23. Used for grinding solids Mortar and pestle

24. Container for high-temperature heating Crucible and cover

25. Container for observing small amount of solids Spot plate

26. Metal Equipment and Accessories

27. Iron stand Used to hold iron ring, utility clamp, etc.

28. Used to hold apparatus in a set-up Iron clamp

29. Placed over the iron ring to prevent direct heating Wire gauze

30. Used as support to the wire gauze Iron ring

31. Used as a stand during heating tripod

32. Sources of heat Bunsen burner/ alcohol lamp

33. Used as a stand for test tubes Test tube rack

34. Cover for test tubes and flasks; used in glass connections Rubber stopper

35. Holds crucible and cover during heating process Clay triangle

36. Used to hold the test tube during heating process Test tube holder

37. Used to hold hot objects, especially crucible and cover Crucible tongs

38. MODERN LABORATORY TOOLS AND THEIR USES pH meter is an instrument used to measure acidity or alkalinity of a solution - also know as pH. pH is the unit of measure that describes the degree of acidity or alkalinity. It is measured on a scale of 0 to 14.

39. COLONY COUNTER a device that is frequently used to count bacterial or other microorganism colonies on a plate that contains a gelled growth medium.

40. CALORIMETER is a device used to measure the amount of heat involved in a chemical or physical process.

41. GALVANOMETER A galvanometer is one of the instruments for measuring electrical current par excellence. This device is used on electrical circuits to know and measure the intensity and direction of electrical current.

42. VOLTMETER The voltmeter is a measurement device used to measure voltage in electrical circuits or electronic devices. It is commonly employed to measure the voltage across a circuit or component, typically expressed in volts.

43. OSCILLOSCOPES Oscilloscopes (or scopes) test and display voltage signals as waveforms, visual representations of the variation of voltage over time.

44. MICROPIPETTE A micropipette is a common laboratory instrument used to measure small amounts of liquids with a volume range between 1 and 1000µl. A micropipette is also used to transfer a precise amount of fluid from one container to another.

45. LABORATORY SENSORS

46. LABORATORY SENSORS Laboratory sensors are used for many different applications and must show excellent accuracy, provide fast readings, and endure long periods without use.
