Redjaro (NS29/32) - Redmagic (NS45/40)

These Premex magnetic stirring couplings with integrated motor are designed for the use on glass reactors and glassware with ground joints. These coupling are a very elegant solution for absolute leak tight stirring applications in lab glassware under vacuum. The conical joint of the coupling has two O-rings which provides the sealing between coupling and the ground joint of the glass.
