A three-prong aluminium rotatable clamp is a type of laboratory equipment used to hold and secure a variety of flasks and glassware in place during experiments. The clamp is made of aluminium and features three prongs that securely grip the glassware.

The rotatable feature allows the clamp to be easily adjusted and positioned at different angles, making it more versatile and useful in a variety of laboratory settings. The aluminium material provides durability and resistance to corrosion, making it suitable for use in many different laboratory environments.

This type of clamp is commonly used in chemistry, chemical engineering, and biology experiments and is an important tool for conducting accurate and precise experiments.
