A burette clamp is a laboratory accessory used to securely hold burettes in place during titration and other precision experiments. It is typically attached to a lab stand or retort stand, ensuring that glassware remains stable and properly aligned.
Burette clamps are essential in analytical chemistry, where even small movements can affect measurement accuracy. Most designs include rubber-coated jaws or spring-loaded grips to prevent slipping and protect delicate glassware.
How Does a Burette Clamp Work?
A burette clamp works by attaching to a vertical support rod and gripping the burette using adjustable jaws. These jaws can:
Apply controlled pressure to hold the burette
Prevent movement during liquid dispensing
Allow easy repositioning when needed
Many modern clamps feature:
Spring-loaded mechanisms
Adjustable jaw openings
Rotating or swivel heads for flexible positioning
Types of Burette Clamps
1. Single Burette Clamp
Designed to hold one burette, suitable for:
Basic titration experiments
Educational laboratories
2. Double Burette Clamp
Can hold two burettes simultaneously, ideal for:
Comparative titration
Demonstrations and teaching
Double clamps are widely used because they improve efficiency and allow side-by-side experiments.
Example Products (Market Reference)
These examples show common features in the market:

Why Use a Double-Sided Burette Clamp?
A double-sided burette clamp offers several advantages:
Holds two burettes simultaneously
Saves lab space
Improves experimental efficiency
Ideal for comparative analysis
Many designs can accommodate burettes up to ~30–35 mm diameter, making them suitable for a wide range of applications.
