Cole-Parmer® Two-Prong Extension Utility Clamps

Securely hold your flasks, beakers and burettes

Ideal for holding straight-sided apparatus such as burets, thermometers, beakers, and flask necks.

Utilizing thumbscrews, both prongs are easily adjusted over a wider range. Available in medium and large sizes. Dual adjustable clamps are offered in either stainless steel or nickel plated zinc. Supplied with non-slip vinyl sleeves or for temperatures above 212°F (100°C), fiberglass covers.
