Chain clamps are widely used experimental tools. They are often used to fix glassware such as beakers, condenser tubes, flasks, large test tubes, etc., which can well protect them from being scratched and avoid experimental errors.
Our chain clips can be used to hold cylindrical labware with diameters of 40mm-180mm (1.6"-7").

The bosshead clamp can be used to fasten chain clamps to laboratory iron racks and other clamps, as well as to clamp test tubes in distillation experiments.
Our bosshead can hold objects up to 21mm (0.8") in diameter and has an overall length of 108m (4.3").

Package include:
1 PCS Chain Clamp + 1PCS Bosshead Clamp (excluding other instruments)
