What Is a Burette? Types, Uses and Buying Guide
Updated On 09/28/2026
Introduction
Precision is key in laboratory experiments, particularly in titration, chemical analysis, and volumetric experiments. One of the most essential tools for achieving accurate and controlled liquid dispensing is the burette.
A burette is a graduated glass tube with a stopcock valve that allows precise control over the release of liquids, making it indispensable for scientific research, quality control, and industrial applications.
In this guide, we’ll explore what a burette is, its types, uses, and how to choose the best burette for your laboratory needs.
What is a Burette?
A burette is a long, cylindrical tube typically made of borosilicate glass or plastic, designed for precise liquid dispensing and measurement. It is commonly used in acid-base titrations and chemical reactions that require high accuracy.
Key Features of a Burette:
✔ Graduated markings for precise volume readings
✔ Stopcock valve to control liquid flow
✔ Glass or plastic construction for chemical compatibility
✔ Typically measures volumes up to 50 mL
Types of Burettes
1️⃣ Glass Burette
🔹 Material: Borosilicate glass
🔹 Best for: High-precision titrations, acid-base chemistry
🔹 Advantages: Chemically resistant, high clarity for accurate readings
💡 Ideal for: Research labs, pharmaceutical testing, and university experiments
2️⃣ Plastic Burette (Polyethylene or PTFE)
🔹 Material: Durable plastic (often PTFE-coated)
🔹 Best for: General laboratory use, field testing
🔹 Advantages: Shatter-resistant, lightweight, ideal for use with certain acids and bases
💡 Ideal for: Schools, environmental testing, and industrial applications
3️⃣ Digital Burette
🔹 Material: Glass or plastic with a digital display
🔹 Best for: High-precision titrations in automated labs
🔹 Advantages: Reduces human error, provides real-time volume readings
💡 Ideal for: Advanced research labs and pharmaceutical testing
Uses of Burettes in Laboratories
A burette is an essential instrument in various laboratory processes, including:
✔ Titration Experiments – Used in acid-base titrations to determine the concentration of unknown solutions
✔ Chemical Analysis – Accurate measurement of reagents in qualitative and quantitative analysis
✔ Food & Beverage Testing – Ensures quality control in pH and acidity analysis
✔ Environmental Testing – Used in water analysis and pollutant detection
✔ Industrial Applications – Assists in quality control for chemical production
How to Use a Burette Correctly
Step 1: Rinse the Burette – Before use, rinse with distilled water and then with the titrant solution to prevent contamination.
Step 2: Fill the Burette – Using a funnel, carefully fill the burette with the titrant solution to the required volume.
Step 3: Remove Air Bubbles – Open the stopcock slightly to let liquid flow and eliminate air bubbles.
Step 4: Take Initial Reading – Read the liquid level at eye level from the bottom of the meniscus.
Step 5: Perform the Titration – Slowly release the titrant dropwise while swirling the solution in the receiving flask.
Step 6: Take Final Reading – Record the volume dispensed for accurate calculations.
Key Factors to Consider When Choosing a Burette
💡 1. Material
- Glass burettes offer better precision and durability but require careful handling.
- Plastic burettes are shatterproof and ideal for field use.
💡 2. Graduation & Accuracy
- Choose a burette with clear, high-contrast markings for easy volume reading.
💡 3. Stopcock Type
- Glass stopcocks offer smooth flow control but may require lubrication.
- PTFE stopcocks are chemical-resistant and require less maintenance.
💡 4. Volume Capacity
- Standard burettes range from 10 mL to 100 mL, with 50 mL being the most common.
💡 5. Digital vs. Manual
- Manual burettes are standard for most labs.
- Digital burettes are recommended for highly precise and automated workflows.

Burette vs Pipette: Key Differences and Which to Use
This guide explains the practical difference between a burette and a pipette, two instruments that are often confused because both dispense measured volumes of liquid, but that are built for genuinely different jobs. It breaks down how a burette's stopcock and full-length graduated scale let an operator dispense a variable, watched volume and stop the instant a reaction reaches its endpoint, versus how a pipette (volumetric, graduated or micropipette) is built to transfer one known or pre-set volume in a single action. Rather than presenting the two as competing options, the piece frames them as complementary tools tied to different steps in a procedure: burettes for titration and any reaction where the target volume isn't known in advance, pipettes for sample preparation, dilutions and any step where the volume is already fixed.
