This stirrer head is fitted with a permanent magnetic coupling and is available to fit conical joints size NS 29/32 and NS 45/40. Manufactured in stainless material according to DIN, No. 1.4435 X2 CrNiMo, absolutely gas and vacuum tight as well as resistant to acids and alkaline solutions. Viton-O-ring seals on the cone avoid friction, heat-expansion and even tension in the glass joint. Minimal driving load. Maximum speed 2500 rpm.
Sealing a straight-through drive shaft with snap rings is unnecessary, since power is transmitted via magnetic coupling. Fast and easy replacement of ball bearings. Operating temperature max. 240°C.
Drive shaft with square brass adapter 6 mm.
Quick, simple replacement of ball bearings.
Magnetic stirrer seals with higher torque, which can be used under pressure, made of other materials (Hastelloy, PTFE, titanium) with flange or screw-in threading, are available on request.
