Three Jaw Clamps for Secure Glassware and Apparatus Support
Three jaw clamps, also known as three-finger clamps or three-prong clamps, are used to hold laboratory glassware and apparatus securely during bench procedures. The three-point grip helps stabilise round or irregular items, while coated fingers help reduce slipping and minimise direct contact damage to glass or delicate surfaces.
- Secure Holding: Designed to hold flasks, tubes, condensers, rods and other laboratory apparatus during setup and handling.
- Protective Grip: PVC-coated fingers help reduce scratching, slipping and pressure damage on supported items.
- Adjustable Range: The visible product range includes a 0-70 mm clamping range for flexible use across common laboratory items.
- Lightweight Construction: Aluminium construction supports practical daily use while keeping the clamp easy to position and adjust.
How to Choose Three Jaw Clamps
Selection should begin with the object being held, the required clamping range and the type of support stand or fixture used in the laboratory. For glassware and delicate apparatus, coated fingers are useful because they help improve grip while reducing the risk of surface damage. For larger or heavier items, confirm the clamp body, jaw range and support setup can safely hold the intended load.
- Clamping Range: Check the maximum jaw opening against the diameter of the flask, condenser, tube or apparatus being held.
- Finger Coating: Choose PVC-coated or similar protective fingers where glassware protection and non-slip holding are important.
- Support Compatibility: Confirm the clamp works with the intended stand, rod or holder arrangement used in the lab.
- Application Fit: Match the clamp to routine laboratory support, small apparatus holding, testing, education, quality control or industrial bench work.

Frequently Asked Questions
What are three jaw clamps used for?
Three jaw clamps are used to hold laboratory glassware, tubes, condensers, rods and small apparatus securely during bench setups, testing, sample preparation and general laboratory work.
Are three jaw clamps the same as three-finger clamps?
Yes, the terms are often used for the same style of clamp. They may also be called three-prong clamps or retort clamps, depending on the supplier or application.
Why use PVC-coated fingers on a laboratory clamp?
PVC-coated fingers help improve grip and protect glassware or delicate equipment surfaces from slipping, scratching and direct metal contact during clamping.
