EPP series

EPP series

Linear & elevation motion

Complete sampling-handling system providing linear motion and up to 50mm of lift in the Y-axis for sample hand-off. Stroke lengths from 304mm to 1219mm and motorisation options available.

The Elevating PowerProbe transforms conventional approaches to sample transfer.

For demanding UHV applications,  we recommend choosing the 'XEPP' option with rolling metal & ceramic bearings for smooth low friction actuation with minimal outgassing.

Key features

  • Up to 50mm of lift in the Y-axis
  • Unrivalled axial coupling strength
  • Exceptional axial stiffness 
  • Zero backlash under low load
  • Bakeable to 250°C without removing any components

In addition to its internally-guided linear motion, the probe has the ability to elevate its end-effector throughout its stroke, providing 12.7mm of lift as standard (with 25mm and 50mm options) in the Y axis for sample hand-off. 

This PowerProbe variant greatly simplifies sample transfer techniques, providing a single device to provide both linear motion for sample introduction and the lift/lower motion to collect or hand-off the sample.

With a range of industry-standard effectors, the Elevating PowerProbe provides a complete sample-handling system in its own right removing the need for secondary motion tools. This reduces cost and simplifies the transfer process.
