ProductsTransfer DevicesWobble Sticks
Wobble sticks enable manual operation to be transmitted through the wall of a vacuum vessel. To enable sample transfer or actuators to operate mechanisms inside a vacuum systems. A range of manually operated manipulators, translating linear and angular hand movement into the vacuum envelope. Our mechanical hands are a range of manually operated manipulators with pincer action, translating hand movement into the vacuum envelope including rotation.
The mechanical hand can be used for the movement, re-arrangement and transfer of samples, STM tip changes, or even as an in-vacuum screw-driver
Based on the existing Universal WS series, with the additional benefit that it has a 3.6mm diameter hole through the centre of the wobble shaft
A very simple version of the wobble stick consisting of a single edge welded bellows which is mounted on the atmosphere side of the mounting flange. This allows movement in all planes, both in and out, and angular
The WS20 wobble stick has 20 mm linear travel and 15° (±7.5°) angular movement
