50 Common Laboratory Apparatuses and Their Uses

1. Beaker

A beaker is a cylindrical glass or plastic container with a flat bottom and a small pouring spout. It is one of the most commonly used pieces of laboratory equipment.

2. Test Tube

A test tube is a narrow cylindrical glass or plastic tube with a rounded bottom. It is widely used in chemistry, biology, and educational laboratories.

3. Measuring Cylinder

A measuring cylinder, also called a graduated cylinder, is used to measure the volume of liquids more accurately than a typical beaker.

4. Conical Flask

A conical flask, also known as an Erlenmeyer flask, has a wide base and a narrow neck.

5. Volumetric Flask

A volumetric flask is designed to contain one specific, accurately defined volume of liquid at a specified temperature.

6. Burette

A burette is a long graduated glass tube fitted with a stopcock that controls liquid delivery.

7. Pipette

A pipette is a laboratory instrument used to transfer measured volumes of liquid.

8. Funnel

A laboratory funnel is a cone-shaped apparatus with a narrow stem.

9. Separating Funnel

A separating funnel is a glass vessel fitted with a stopcock, generally used for separating immiscible liquids.

10. Watch Glass

A watch glass is a shallow, circular piece of glass commonly used in chemistry laboratories.

11. Glass Stirring Rod

A glass stirring rod is a solid glass rod used to mix liquids and solutions.

12. Spatula

A laboratory spatula is a small tool made from metal, plastic, or another chemically compatible material.

13. Mortar and Pestle

A mortar and pestle consist of a bowl and a handheld grinding tool.

14. Crucible

A crucible is a heat-resistant container made from materials such as porcelain or suitable metals.

15. Crucible Tongs

Crucible tongs are specially designed gripping tools used to handle hot crucibles and other compatible laboratory objects.

16. Test Tube Holder

A test tube holder is a device used to grip a test tube, especially during heating.

17. Test Tube Rack

A test tube rack is a stand designed to hold multiple test tubes upright.

18. Retort Stand with Clamp

A retort stand is a heavy base with a vertical rod, often used with adjustable clamps.

19. Wire Gauze

Wire gauze is a metal mesh, sometimes containing a heat-resistant ceramic centre, placed on a support ring.

20. Tripod Stand

A tripod stand is a three-legged support used in laboratories, commonly with wire gauze.

21. Bunsen Burner

A Bunsen burner is a gas-powered laboratory heating device that produces a controlled flame.

22. Laboratory Thermometer

A laboratory thermometer measures temperature and may use digital sensors or other suitable temperature-measuring technology.

23. Analytical Balance

An analytical balance is a precision instrument designed to measure small masses accurately.

24. Top Loading Balance

A top-loading balance is a weighing instrument commonly used for routine laboratory measurements.

25. Electronic Weighing Balance

An electronic weighing balance uses an electronic sensor to determine mass and display the result digitally.

26. pH Meter

A pH meter is an electronic instrument used to measure the acidity or alkalinity of a solution.

27. Microscope

A microscope is an optical instrument used to magnify objects that are too small to be observed clearly with the naked eye.

28. Centrifuge

A centrifuge is a laboratory instrument that separates components of a sample through rapid rotation.

29. Hot Plate

A laboratory hot plate is an electrically powered device used to heat vessels and their contents.

30. Magnetic Stirrer

A magnetic stirrer mixes liquids using a rotating magnetic field and a magnetic stirring bar.

31. Laboratory Water Bath

A water bath maintains samples at a controlled temperature using heated water.

32. Incubator

A laboratory incubator maintains a controlled environment, particularly temperature, for specific experiments.

33. Laboratory Oven

A laboratory oven is used to heat, dry, or condition materials under controlled temperature conditions.

34. Autoclave

An autoclave sterilizes suitable equipment and materials using pressurized steam at controlled temperature and exposure time.

35. Distillation Apparatus

A distillation apparatus typically consists of a distillation flask, condenser, receiving vessel, and associated connections.

36. Condenser

A laboratory condenser is a glass apparatus designed to cool vapour and convert it back into liquid.

37. Dropper

A dropper is a small instrument used to dispense liquids in individual drops.

38. Wash Bottle

A wash bottle is a squeezable container with a narrow dispensing nozzle.

39. Reagent Bottle

A reagent bottle is a container designed to store chemicals and laboratory solutions.

40. Desiccator

A desiccator is a sealed container used to maintain a low-moisture environment with a suitable desiccant.

41. Filter Paper

Filter paper is a porous material used to separate solid particles from liquids.

42. Glass Slide

A glass slide is a thin, flat piece of glass used to hold specimens for microscopic observation.

43. Cover Slip

A cover slip is a thin glass or suitable plastic sheet placed over a specimen on a microscope slide.

44. Hemocytometer

A hemocytometer is a specialized counting chamber with a precisely ruled grid.

45. Micropipette

A micropipette is a precision instrument designed to transfer very small liquid volumes, commonly measured in microlitres.

46. Vortex Mixer

A vortex mixer is a laboratory device that rapidly mixes small liquid samples in tubes.

47. Fume Hood

A laboratory fume hood is an engineered ventilation enclosure designed to reduce exposure to hazardous vapours, gases, and certain airborne contaminants.

48. Laminar Airflow Cabinet

A laminar airflow cabinet supplies filtered air across a work area to reduce contamination of materials within that area.

49. Conductivity Meter

A conductivity meter measures the electrical conductivity of a liquid, which is related to the concentration of dissolved ions.

50. Spectrophotometer

A spectrophotometer measures how much light a sample absorbs or transmits at selected wavelengths.
