“I would be delighted to be a reference. You can forward my details to them and I’m happy to show them your system as well as give a demo, or just answer any questions they may have. So far, the Tergeo-plus system has been extremely well received.”

– Dr. Kal Banger, The Rowland Institute at the Harvard University

“The cleaner has been installed and is working very well so far. It’s a great tool, very versatile and user friendly.” Dr. Matthew S. Hunt purchased three plasma systems from PIE Scientific so far.

The Tergeo cleaner allows us to realize a simple PDMS‐glass bonding process in a very efficient way. The integrated electronics save space and the touch screen is responsive and convenient enough. The treatment works very well and a curing step in an oven to improve the bonding efficiency is no longer needed

– Dr. Marc Fouet at Department of Molecular & Cell Biology, UC-Berkeley


Everything is working great! I am quite happy with the plasma cleaner. I find it quite flexible for TEM holders, holders with samples, grids, etc. I have used it successfully with a very gentle remote plasma source setting to regularly clean the tuning samples for aberration-corrected STEM.

– Dr. James C. Mabon, University of Illinois at Urbana-Champaign
