Overview

BUK magnetic stirrer coupling with thread and valve

An additional purging gas connection valve is fitted laterally to this magnetic stirrer coupling. The mounting onto an autoclave lid is by means of the M30x2 thread connection. Sealing to the autoclave lid by a cutting ring (HC 22)*, see accessories. A reed contact and speed sensor at the output shaft is fitted as standard.

Magnetic stirrer couplings are available in stainless steel, Hastelloy^®, titanium, zirconium and other materials or offering alternative torque levels.
