Magnetic stirrer coupling (P-MRK), glass+PTFE

Magnetic stirrer coupling (P-MRK)

• Ideal stirrer head for PTFE-jacketed stirrer shafts from BOLA.
• Consisting of capsuled drive shaft (stainless steel) with ball bearings, rotor and lower bearing made of PEEK-Compound and a borosilicate glass receiver.
• Requires little space due to compact construction.
• No leakage or memory effects due to non-porous, welded rotor.
• Compression fittings for safe fixing of stirrer shaft and optimum power transmission.
• Joint-cone with nut (Safe-Lab) made of PTFE for easy locking and unlocking of the ground joint.
