This precise screw mechanism is available with manual or motorized "screw-drive" actuation. This unit can be stopped at any intermediate position between its travel limits, and offers an integrated scale into the body of the device for accurate and repeatable positioning.
Many different devices are associated with sample manipulation: motion feedthroughs, sample transfer, translation devices, xyz manipulation, z-only manipulation, sample rotation, rotary drives, linear drives, wobble sticks, etc. All cover different aspects of the same basic requirementâ€” to mechanically move an object that is inside a vacuum chamber and under vacuum. Such devices provide precise, repeatable movement or coarse positioning and may provide rotary motion, linear motion, or a combination of both.
The most complex devices give motion in three axes and rotations around two of those axes. The mechanical movement may be generated by two basic mechanisms: a vacuum-tight seal on a mechanical device that moves through the vacuum wall or a magnetic coupling that transfers motion from air-side to vacuum-side.
As always, if you don't see a sample manipulation or motion device listed, contact us with your specific process requirements.
