VWR® Talon® Three-Prong Extension Clamps

Clamps securely hold every type of glassware and apparatus.

  • Large grip adjustment range
  • Three-prong construction
  • Choose single or dual adjustment
  • Stainless steel or nickel-plated zinc
Long, seamless tubing attaches clamp head securely and offers easy positioning in the deepest fume hoods. Clamps are constructed with round extension arms that allow the clamps to be rotated 360°. Extension arms allow placement of apparatus at various distances from lab frames without compromising the integrity of the experiment. Stainless steel clamps offer exceptional chemical resistance, and are electropolished, made entirely of stainless steel, and autoclavable. Nickel-plated zinc offers a clamp with a high tensile strength at an economical price. Supplied with non-slip vinyl sleeves, and fiberglass covers for temperatures above 100°C.

Ordering information: An additional holder must be purchased in order to attach clamps to frames or other apparatus.
