About This Product
A lab jack lets a heat source or stirrer be brought up to a flask that is already clamped, then lowered away quickly when heating has to stop. It is used to line up ground-glass joints in distillation and reflux assemblies and to set the height of a stirrer under a titration flask. Educational Instrument can arrange export supply of the Laboratory Jack to Burundi, Senegal, Liberia, Afghanistan and Philippines.
