The unique design enables secure gripping and positioning with added strength and durability and has a grip size for up to 4.06 inches.

The design of the CLMULTRA3DZL features precise pressure regulation when gripping glassware surfaces to reduce the chance of breakage. The UltraJaws clamps are constructed with extension rods for easy attachment to lab-frames and other apparatus. Supplied with non-slip vinyl sleeves and fiberglass covers for temperatures above 100° C.

The prong height of the UltraJaws Heavy-Duty Clamps make them ideal for use in holding and securing glassware with precision ground glass joints.

Our Multi-Purpose Clamps are designed to securely grip and position laboratory apparatus. Extension arms with a 360° rotation allow placement of apparatus at various distances from lab-frame without compromising experiment integrity. Swivel & fixed position clamps hold apparatus near the lab-frame or stand, and have a built-in integral holder for attaching to lab-frames or apparatus. Available as single or dual-adjust in zinc or stainless steel.

Nickel-plated zinc clamps offer high-tensile strength at an economical price. Corrosion-resistant stainless steel clamps provide excellent chemical resistance, durability, and are autoclavable.

2-prong clamps are ideal for holding straight-sided apparatus such as burets, thermometers and flask necks. The more versatile 3-prong clamps are designed for holding irregularly-shaped objects.

Dual adjust clamps are designed to hold large vessels. Both prongs open gradually to maximum grip size without binding. Precise pressure regulation when gripping glassware reduces chance of breakage.
