Below is a detailed list of common laboratory equipment along with their uses:

1. Glassware & Plasticware

a) Beaker

Use: Used to hold, mix, and heat liquids. It has a wide mouth and a spout for easy pouring.

b) Erlenmeyer Flask (Conical Flask)

Use: Used for mixing, heating, and storing liquids. The narrow neck minimizes evaporation and spillage.

c) Volumetric Flask

Use: Designed for precise measurement of specific liquid volumes. It is commonly used in preparing solutions of exact concentrations.

d) Test Tube

Use: Used to hold small amounts of substances for chemical reactions, heating, and mixing.

e) Graduated Cylinder

Use: Used to measure liquid volume accurately. It has graduation marks to indicate different volume levels.

f) Burette

Use: Used in titrations to deliver precise volumes of a liquid reagent. It allows controlled addition of liquids.

g) Pipette

Use: Used to transfer small volumes of liquid accurately. Comes in different types:

  • Volumetric Pipette – Measures and delivers a single, specific volume.
  • Micropipette – Used for extremely precise measurement of very small liquid volumes.

h) Petri Dish

Use: Used for culturing bacteria, fungi, and other microorganisms in microbiology labs.

i) Watch Glass

Use: Used to hold small samples, evaporate liquids, or cover beakers.

j) Funnel

Use: Helps transfer liquids into narrow-mouthed containers to avoid spills. Also used for filtration.

k) Reagent Bottle

Use: Used to store chemical solutions, acids, and bases safely.


2. Heating Equipment

a) Bunsen Burner

Use: Provides a single open flame for heating substances in test tubes, beakers, or crucibles.

b) Hot Plate

Use: Used to heat substances evenly, especially when direct flame is not ideal.

c) Water Bath

Use: Used for heating samples at a controlled temperature without direct contact with a flame.

d) Heating Mantle

Use: Used to heat flammable liquids evenly without open flames.

e) Crucible and Lid

Use: Used for heating substances at high temperatures, often for melting or decomposing solid materials.


3. Measuring Instruments

a) Analytical Balance

Use: Used to measure small masses with high precision (up to 0.0001g).

b) Triple Beam Balance

Use: A less precise balance used for measuring mass in general lab work.

c) Thermometer

Use: Measures temperature of liquids, gases, or solid substances in experiments.

d) pH Meter

Use: Measures the acidity or alkalinity of a solution.

e) Spectrophotometer

Use: Measures the absorbance of light by a sample to determine concentration.

f) Conductivity Meter

Use: Measures the electrical conductivity of a solution, often used in water quality testing.

g) Refractometer

Use: Measures the refractive index of a liquid to determine concentration or purity.

h) Manometer

Use: Measures gas pressure in closed systems.


4. Microscopy & Imaging

a) Compound Microscope

Use: Used for magnifying small specimens like bacteria, cells, and tissue samples.

b) Stereo Microscope

Use: Provides a 3D view of larger specimens, such as insects or plant parts.

c) Electron Microscope

Use: Uses electron beams instead of light to achieve much higher magnification for studying cell structures and nanoparticles.

d) UV Transilluminator

Use: Used in molecular biology labs to visualize DNA, RNA, or proteins after gel electrophoresis.


5. Laboratory Safety Equipment

a) Fume Hood

Use: Removes hazardous chemical fumes and vapors from the lab to ensure safe air quality.

b) Safety Goggles

Use: Protects eyes from chemical splashes and flying debris.

c) Lab Coat

Use: Protects clothing and skin from spills and splashes.

d) Gloves

Use: Protects hands from hazardous chemicals, heat, and contamination.

e) Eyewash Station

Use: Provides immediate rinsing in case of chemical exposure to the eyes.

f) Fire Extinguisher

Use: Used to put out laboratory fires. Different types exist for electrical, chemical, and combustible material fires.


6. Miscellaneous Lab Equipment

a) Mortar and Pestle

Use: Used for grinding and mixing solid substances into fine powder.

b) Desiccator

Use: Used to store moisture-sensitive materials to keep them dry.

c) Centrifuge

Use: Used to separate substances of different densities using rapid spinning motion. Common in medical and biochemical labs.

d) Incubator

Use: Provides controlled temperature conditions for growing microbial or cell cultures.

e) Autoclave

Use: Uses high-pressure steam to sterilize lab equipment and biological materials.

f) Laminar Flow Hood

Use: Provides a sterile, particle-free environment for working with sensitive biological materials.

g) Chromatography Apparatus

Use: Used for separating components of a mixture based on their movement through a medium.

h) Electrophoresis Apparatus

Use: Used in molecular biology to separate DNA, RNA, or proteins based on size and charge.

i) Tongs and Forceps

Use: Used for handling hot, delicate, or hazardous substances.
