Epoxy Adhesive to the Rescue! Exceptional strength m d relative chemical inertness make the epoxy cementa suitable for repairing broken equipment where other methods would be quite difficult. Oocasionally the tip of a buret or separatory funnel will be broken offso close t o the stopcock that repair b y simple glhss working techniques is impractical. I n such instances, it may be worthwhile to cement the broken part, or a replacement, to the stopcock barrel. The writer has seen such items as a McLeod gauge, a cast iron support bracket, a glass hydrometer jar, and a glsss-to-metal seal which were satisfactorily repaired with epoxy. Because of its high electrical mistanoe, epoxy adhesive may be used as a n insulating coating for a metallic surface, for mounting electricd extension cords to walk or other surfaces, and for fastening electrical components to chassis. I t is also useful for recementing loose tube bases to their glass envelopes. Wires of materiala not readily soldered may be joined by tightly twiwting the wires together and applying a very small amount of the adhesive t o each end of the twisted jw~tion.
