Wobble Stick WSG40 - Linear & Rotary Motion with Gripper Options

WSG range provides combined tilt, linear, rotary motion and fourth axis gripper.

The wobble stick is one of the simplest manipulation tools available, translating hand movements, with defined freedom, through a vacuum enclosure. The wobble stick series has been newly redesigned to increase the effective tilt of this unit. This wobble stick continues to utilize UHV Design's magnetically coupled technology for linear, rotary, and gripper movements.

Design Concept

The Wobble Stick is a modular concept. The basic design provides lateral/tilt movement through a robust edgewelded bellows adaptor with linear push/pull motion and rotation through a powerful magnetic coupling. The newly redesigned Wobblestick has an upgraded tilt of +/- 22°.

Magnetic Coupling

The UHV Design wobble stick is a slim line modular concept benefiting from UHV Design's high power magnetic coupling technology. The coupling eliminates the need for long edge-welded bellows stacks for linear movement, typically employed with conventional wobble stick designs. Because of this, the UHVD wobble stick is not subject to the thrust due to vacuum, resulting in smooth, free-moving operation.

Gripper & Pincer End Effectors

This design offers both pincer and gripper end effectors for sample stub handling actuated via a hand-operated trigger mechanism. This gripper unit has both In-line and right-angle end effector options for flag, puck and the ESCA stub. The Pincer should be considered as a universal sample grip system suitable for the majority of small sample handling applications but also suits our "flag" style sample mount.
