The next milestone of the smallest: minifiz
This magnetic stirring head stands, on the one hand, as godparent to the drive shaft of the mini-series and, on the other hand, as the proven conical connection NS 29/32 of the glenfiz. From the "mini" and "glenfiz" follows a fusion of the design and the name. The new one is called minifiz.

The core of the matter
The core of every magnetic stirrer is the magnetic force that is transmitted from the outer magnets to the inner magnets. Thereby, the output shaft is driven by the mutually attracting magnetic fields, without contact.

Technical Data
  • Conical connection NS 29/32
  • Sealing to the reactor cover using two O-Rings, one behind the other. For the stainless steel design, made from viton, or Kalrez for use with HC.
  • Torque of the magnetic coupling 20 Ncm or 50 Ncm.
  • Material WNo. 1.4435 (AISI 316L) or Hastelloy C22 as standard.
  • Operating temperature 200 °C
  • The magnetic stirring head minifiz is suitable for the vacuum or pressureless situation.
  • Designs in Hastelloy C276, B3 or titanium Size 2 on request.
  • Stainless steel ball bearing mounting on the output shaft. Hastelloy or Titanium versions with friction bearing mounting PTFE/carbon.
  • Maximum speed 1750 rpm for ball bearing mounting.
  • Drive shaft (coupled to the drive on site) ø 7 mm
  • Output shaft ø 6 mm
  • Suitable stirrer, such as for example, aeration stirrers ø 25 mm are available in various lengths
  • The complete length for a minifiz, 20 Ncm is 148 mm


The cirrus and movic are similar magnetic stirring heads to the minifiz. They have the same striking, red drive shaft. They primarily differ in the standard joints. Minifiz emanates from a conical connection NS 29/32, the cirrus NS 29/16 and movic NS 14/23.
