What We Do

element Pi, LLC is the distributor for COXEM Co, Ltd. of  South Korea supporting customers in both North and South America with a min office and product demonstration lab located near Portland, Oregon. We currently distribute the COXEM Series of Tabletop and Full-Size SEM (Scanning Electron Microscopes) along with a variety of accessories such as Sputter Coaters, Ion Mill Polishers, a Laser Micro-Machining sample preparation tool, Plasma Cleaners, Vibration Isolation solutions, microscopy software and more which are marketed under our brand “microPREP” and a dedicated website www.micro-prep.com and www.nano-prep.com.

We are proud to offer these exceptional products that have a superior price-to-performance ratio compared to similar SEM systems on the market.  We are confident that after making an in-depth comparison, you will come to the same conclusion.

The EM-30 Series of Tabletop SEM offers a solution that cannot be matched at the same price by any other Desktop or Tabletop SEM on the market.  Even more advanced and powerful solutions were introduced in 2019 and more will follow in 2020 and beyond.

The PRICE of the CX-200plus full-size SEM is sure to surprise you and with its robustness and ease-of-use, and its compact size.  Many customers think they must go to a tabletop SEM in order to get ease-of-use and something that will fit into a cramped lab space.  The CX-200plus is almost the same footprint as a tabletop SEM, only placed on the floor instead of a benchtop or table.  You may find yourself placing them right on your factory floor close to production lines for fast, easy high magnification imaging, elemental micro-analysis or automated particle analysis.

Both the new EM-30 NEXT and the CX-200plus are also available with Automated Particle and Feature Analysis capabilities using ASTM and ISO compliant analytical workflows for Steel, Gunshot Residue (GSR), Technical Cleanliness, Equipment Monitoring, Automotive, Aerospace, Mining, Geology and Pharmaceutical applications including Large Area Mapping

Our NEW Ion Beam Cross Section Polisher (CP-8000) presents a sample preparation solution at an affordable price compared to other manufacturer solutions in the $100,000 range and above.  Ion Milling preparation of cross sectioned samples has yet to realize its full potential in the microscopy market due to the previous high cost of  this type equipment.  There is no better surface finish than the atomic level polish produced by an Ion Mill.

A NEW STEM option for Tabletop SEM was introduced spring of 2019.  STEM is Scanning Transmission Electron Microscopy. With the 30kV beam energy of the EM-30 NEXT, this new STEM option promises to allow users of Tabletop Scanning Electron Microscopes to utilize the microscope for many types of TEM or Transmission Electron Microscope analysis of nanoparticles and standard tissue sections.  The STEM option promises to be a great teaching tool for Life Science educators as well as a pre-screening tool for high throughput TEM laboratories, possibly even replacing some tests with lower requirements given the low entry price for this combination of analytical capabilities.


So why Pi in our company name you might be wondering?  Pi is the most recognized mathematical constant and often considered the most intriguing and important number in all of mathematics.  So in the spirit of Pi, we offer products that will continue to intrigue you as new developments are reached and our goal is to make our products become an important asset to your research and microscopy effort.  However, while Pi is an irrational number like its cousins “e” and “√2” that like to go on forever, we will offer nothing but rational explanations and advice when it comes to selecting the best product solution.  Through your use of our products, we promise that “Pi” will come to mean “Precision Imaging” that you can count on.

We would treasure your comments about how we could make our website better with more useful information to assist with your search for Microscopy solutions. Take a minute and enjoy the Pi FACTS we have collected and presented on our Company – About Us page.
