WS40 Wobble Stick Range

Magnetically-coupled wobble stick

The WS40 range has been designed to offer precise manual manipulation of a variety of sample holders. This is because it utilises 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. This allows secure transfer of flag style sample holders via an innovative 'twist & lock' mechanism; intuitively designed to prevent accidental damage to the flag sample handle.

Key Specifications

  • In-line and right-angled version with +/-22° tilt
  • 100-350mm stroke range (50mm increments) - Note: longer strokes are available upon request. Contact us for details.
  • Bakeout to 250°C 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
