A laboratory apparatus burette is one of the most important pieces of volumetric glassware used in chemistry, pharmaceutical, educational, research, and industrial laboratories. It is specially designed to dispense highly accurate volumes of liquid during titration and quantitative chemical analysis. A burette consists of a long graduated tube fitted with a stopcock at the bottom that allows precise control of liquid flow, making it an essential instrument for experiments requiring high accuracy.

What is a Laboratory Burette?
A burette (also spelled buret) is a precision laboratory apparatus used to measure and deliver exact volumes of liquids. It is primarily used in acid-base titrations, redox reactions, water testing, pharmaceutical analysis, and quality control laboratories. The graduated markings on the tube allow scientists to determine the volume of liquid dispensed with exceptional accuracy.
Main Parts of a Burette
A standard laboratory burette includes:
- Graduated glass tube
- Stopcock valve (glass or PTFE)
- Fine dispensing tip
- Filling opening
- Graduation scale for accurate volume measurement
These components work together to ensure precise and controlled liquid dispensing.
Types of Laboratory Burettes
1. Glass Burette
Manufactured from high-quality borosilicate glass, ideal for laboratories requiring excellent chemical resistance and accuracy.
2. PTFE Stopcock Burette
Designed with a PTFE (Teflon) stopcock for smooth operation, leak resistance, and long service life.
3. Automatic Burette
Used where repetitive titrations are performed, improving laboratory efficiency and reducing manual errors.
4. Digital Burette
Offers electronic measurement with superior precision and is commonly used in research laboratories.
Applications of Laboratory Burettes
Laboratory burettes are widely used in:
- Chemical laboratories
- Pharmaceutical laboratories
- Educational institutions
- Food testing laboratories
- Water treatment plants
- Environmental testing laboratories
- Biotechnology laboratories
- Industrial quality control laboratories
- Research and development centers
Advantages of Using a Burette
- High measurement accuracy
- Controlled drop-by-drop liquid dispensing
- Easy-to-read graduations
- Excellent chemical resistance
- Suitable for quantitative analysis
- Durable and reusable
- Reliable experimental results
How to Use a Laboratory Burette
- Clean the burette thoroughly before use.
- Rinse it with the solution to be used.
- Fill the burette above the zero mark.
- Remove any trapped air bubbles.
- Record the initial reading at eye level.
- Dispense the liquid slowly using the stopcock.
- Record the final reading to determine the exact volume delivered.
Maintenance Tips
- Wash immediately after use.
- Store vertically to prevent damage.
- Check the stopcock regularly for smooth operation.
- Avoid sudden temperature changes.
- Handle glass burettes carefully to prevent breakage.
A laboratory burette is an indispensable instrument for accurate liquid measurement and titration in scientific laboratories.
