The Sample Parking Stage for flag style sample plates is commonly used in surface analysis instrumentation. With that in mind, it’s been specifically designed to accommodate Omicron, Specs and Aarhus Flag style sample plates. Its intended use is the storage of multiple samples in the UHV analysis chamber or the sample preparation chamber. The Sample Parking Stage is comprised of a carousel plate or multiple carousels (each of which can accommodate 4 flag style sample plates).

The UHV Design wobble stick is a slimline modular concept, benefiting from high-power magnetic coupling technology. The coupling eliminates the need for long edge-welded bellows stacks - typically found in conventional wobble stick designs. Crucially, this reduces the risk of leaks - particularly for deposition applications, e.g, MBE. In these applications, particulates or deposition between bellows convolutions can reduce lifetimes or cause immediate failure.

We have a range of Wobble Sticks specifically designed for common VT-SPM systems.

Our products are designed for high-duty, high-torque and high-precision, linear-only applications. For high-duty process applications, these magnetically-coupled push pull (MPP) devices are ideally suited. This is because they offer high torque, high axial stiffness and zero thrust due to vacuum. The magnetically-coupled push pull range provides linear and linear/rotary motion solutions with up to 300mm (12") stroke. Strong magnetic coupling eliminates the use of bellows and dynamic seals, which are vulnerable to failure. This ensures the device has a robust long-life design.

For applications where precise multi-positioning is required, our linear bellows drives provide exceptional resolution (two-times better than conventional units), a guaranteed minimum lifetime of 10,000 cycles and the ability to easily motorise in the field.
