The 2-Prong Extension Clamp is designed to clamp onto the mouth of a flask or test tube, so that experiments can performed on the contents in a laboratory setting. The 2-Prong Extension clamp attaches to a laboratory support stand with a clamp holder. The extension arm of this clamp measures 14cm, allowing for positioning of a sample inside of a fume hood. This clamp has non-slip vinyl pads on the contact surfaces.
