Magnetic stirrer heads consist of perfect combination of drive shaft with ball bearings, rotor and lower bearing made of PTFE and a conductor made of borosilicate glass.

• No grease required
• Safe to run dry
• Long durability and compact size
• No leakage or memory effects due to non-porous, welded rotor
• Temperature range: −100 to 240 °C
• Chemical resistance

The rotor of this unit holds the stirrer shaft by means of three stud screws which are fixed in the counterbores of the stirrer shaft. The 6 mm square can be fixed into the stirrer coupling or into the agitator.

The outer Ø of space saving drive shaft is measured as 28 mm and 38 mm for NS 19/26 and NS 29/32 or NS 45/40 respectively.
