Magnetic dumbbell stir bars: PTFE-encapsulated magnetic core (Alnico 5), universal chemical resistance. Side stable sliding disks ensure an excellent stirring effect.
Color-Magnet-Stirstick. Magnetic core coated with PTFE (Alnico 5), cylindrical shape with central ring, universal chemical resistance.
Cross magnet stir bars. PTFE-coated magnetic core (Alnico 5), universal chemical resistance.
Gas-tight permanent magnetic coupling with encapsulated ceramic ball bearings, square socket on top for connecting a cardan joint and PTFE core NS 29 with extraction nut made of PTFE glass fiber for problem-free loosening of the grinding. All parts that come into contact with the medium are metal-free. The 8 mm shaft holder allows agitator shafts to be guided without abrasion at speeds of up to 800 revolutions per minute. By attaching the enclosed metal adapter to the square socket (edge length 6 mm), it is also possible to mount it directly in a collet.
PTFE-coated magnetic core (Alnico 5) in the middle of a guide cage PTFE mounted, universal chemical resistance.
Perfect combination of drive bell with ball bearings, rotor and lower bearing made of PEEK compound, as well as a guide tube made of borosilicate glass. Small space requirement due to compact design. No leaks or memory effects thanks to the pore-free, welded-in rotor and which 3 grub screws reach into the countersinking of the agitator shaft and drive it with optimal power transmission and at the same time fix it securely in height. The square has a wrench size of 6 mm and serves as a holder for the agitator coupling or the agitator drive. Applications: Ideal for reactor lids with center ground joint, for glass or stainless steel agitator shafts with countersinks for secure fixation in the rotor.
Consists of an encapsulated drive bell (stainless steel) with ball bearings, rotor and lower bearing made of PEEK compound as well as a stirrer shaft holder made of borosilicate glass. Small space requirement due to compact design. Pore-free, welded-in rotor prevents leaks and memory effects. Compression fitting made of PEEK compound for secure attachment of the agitator shaft and optimal power transmission. Ground joint core with Combi nut (Safe-Lab) made of PTFE for securing and easy loosening of the conical ground joint. Square with 6 mm wrench size to accommodate the stirrer drive or a stirrer coupling. Applications: • For all BOLA agitator shafts with a PTFE coating, ideal for reactor lids with a center ground joint • L1 The maximum stirrer shaft length corresponds to the inside height (top edge of the ground section to the bottom of the vessel) Features: • Gas-tight stirrer coupling for perfect vacuum • Height-adjustable agitator shafts, approx. 40 mm • Also suitable for shortened agitator shafts • Powerful power transmission up to 90 Ncm • Excellent chemical resistance • Suitable without lubricants / dry running • High speed up to a maximum of 1,500 revolutions / minute • Fixed drive bell - for your safety • Long service life • Simple dismantling of the individual parts for cleaning • With stirrer shaft holder made of borosilicate glass for universal chemical resistance
