Reproducible and Precise Ion Polishing with the PIPS II System

The precision ion polishing system (PIPS™) II is a ground-breaking advancement of the PIPS ion mill system, which has established the standard for transmission electron microscope (TEM) sample preparation for more than two decades.

The PIPS II system integrates the patented WhisperLok® system with an X, Y positioning stage to ensure accurate centering of the milling target. A 10 in touch screen is also incorporated by the PIPS II system for easy use and better reproducibility and control of the milling process.

The polishing process is controlled using a the digital zoom microscope in real time. It is also possible to store the color images in DigitalMicrograph® (DM) software to carry out the reviewing and examining processes when the sample is in the TEM.

Key Features

  • Digital zoom microscope: Works in real time during the milling process
  • WhisperLok with X, Y stage: Capable of centering the target area for re-polish
  • LN2 specimen cooling: Removes artifacts
  • Color image storage in DM software: Capable of storing and utilizing optical images containing the TEM and EELS data in the same format
  • Variable energy from 0.1 to 8.0 kV: Enhanced low energy milling to obtain reduction in amorphous layer for rectified TEMs
  • 10 inch color touch screen control: Simple but total control from the graphical user interface (GUI)
  • Low energy focusing penning ion guns: Enhanced low energy milling for focused ion beam (FIB) prepared samples


  • Ceramics
  • Metals (alloy, oxide)
  • Semiconductor
