The Flex-Coupling allows 10mm glass stirring rods to be used with a motor drive. The coupling uses a 3" long epoxy-coated spring to compensate for misalignment, reduces the chance of breakage, and eliminates the need for special adapters. The glass shaft is secured by means of a silicone rubber insert and the top bushing will accept a 5/16" OD motor rod and is tightened by means of an Allen screw.
