WS40 Range

Magnetically-coupled wobble stick

The WS40 range of wobble sticks have been designed to offer precise manual manipulation of a range of sample holders using UHV Design's high power magnetic coupling technology.

The slimline modular design provides in-line and right-angle variants along with a choice of end-effectors for Flag, Puck and ESCA stub style sample holders.

The WS40 includes the 'Flag in-line toggle' option which allows secure transfer of flag style sample holders with innovative 'twist & lock' mechanism that prevents accidental damage to the flag sample handle.

  • 100-350mm stroke range (50mm increments) -  Note: longer strokes are available upon request. Contact us for details.
  • Bakeout to 250oC without the need to remove the outer magnet assembly
  • Choice of end effectors for flag, puck and esca stub (see below)
  • No thrust due to vacuum
