Three-Finger Clamp, Double Adjustment, PVC-Lined Fingers

Laboratory three-finger clamp with double adjustment mechanism. Holds flasks, condensers, burettes, chromatography columns and any cylindrical item in assemblies on a universal stand. Fingers are PVC-lined to protect glassware from direct metal contact.

Available Versions

• Version A — without boss head: For use when a boss head is already fitted to the stand rod. Direct connection — reduces overall assembly weight.
• Version B — with boss head: Boss head integrated. Ready to fix directly onto a rod with no additional accessories.

Specifications

• Fingers: Three, PVC-lined — protect glassware and provide grip without marking
• Adjustment: Double — finger aperture and angle relative to support, independently controlled
• Body: Metal with finish resistant to routine laboratory corrosion

Typical Applications

Distillation, reflux, liquid-liquid extraction and column chromatography setups. Any situation requiring a cylindrical item held securely at the correct height throughout the procedure.

PVC lining is particularly important when working with thin-walled or precision glassware — prevents overtightening from causing breakage.

Compatibility

Compatible with standard universal stand rods. Version with boss head (B) fits rods of standard laboratory diameter. Version without boss head (A) requires a separately installed boss head.
