- Available in various sizes, usually marked with volume measurements.
-
Erlenmeyer flask
- Features a conical shape with a flat bottom and narrow neck.
- Ideal for mixing solutions by swirling without risk of spillage.
- Can be used for heating and is often used in titrations.
-
Graduated cylinder
- Tall, narrow container used for accurately measuring liquid volumes.
- Marked with graduation lines for precise volume readings.
- Typically made of glass or plastic and comes in various sizes.
-
Pipette
- A slender tube used to transport a measured volume of liquid.
- Can be manual or automatic, allowing for precise liquid handling.
- Essential for transferring small amounts of liquids in experiments.
-
Burette
- A long, graduated glass tube with a stopcock at the bottom.
- Used for dispensing precise volumes of liquid, especially in titrations.
- Allows for controlled release of liquid, enhancing accuracy.
-
Test tube
- A cylindrical glass or plastic tube used for holding small amounts of liquid.
- Commonly used for mixing, heating, or observing chemical reactions.
- Can be placed in a test tube rack for stability during experiments.
-
Watch glass
- A circular, shallow glass dish used to cover beakers or evaporate small amounts of liquid.
- Helps prevent contamination and evaporation of samples.
- Can also be used as a surface for weighing small solids.
-
Crucible
- A small, heat-resistant container used for heating solid substances to high temperatures.
- Often made of ceramic or metal, suitable for chemical reactions.
- Used in processes like melting, calcining, or burning materials.
-
Bunsen burner

-
Ring stand
- A metal stand with a vertical rod and various attachments.
- Provides support for holding equipment like burettes or flasks during experiments.
- Enhances stability and safety when conducting reactions.
-
Thermometer
- An instrument used to measure temperature in degrees Celsius or Fahrenheit.
- Can be digital or glass, with a scale for easy reading.
- Essential for monitoring temperature-sensitive reactions.
-
pH meter
- An electronic device used to measure the acidity or alkalinity of a solution.
- Provides precise pH readings, crucial for many chemical processes.
- Often used in titrations and quality control in laboratories.
-
Analytical balance
- A highly sensitive scale used for measuring mass with great precision.
- Typically enclosed to prevent air currents from affecting measurements.
- Essential for preparing solutions and conducting quantitative analysis.
-
Volumetric flask
- A glass flask with a long neck and a flat bottom, designed for precise volume measurements.
- Used for preparing standard solutions and dilutions.
- Marked with a single graduation line for accuracy.
-
Distillation apparatus
- A setup used to separate components of a mixture based on differences in boiling points.
- Typically includes a distillation flask, condenser, and receiving flask.
- Essential for purifying liquids and analyzing chemical compounds.
