X-ray crystallography
Proto is excited to launch its newest product line featuring single-crystal diffractometers for x-ray crystallography. Your research deserves the best equipment on the market, and Proto is committed to delivering the most advanced, configurable systems available. From our proprietary high-precision bearings to advanced detector and micro-focus x-ray source options, your instrument will provide years of meaningful results.
With systems optimized for small-molecule crystallography, protein crystallography, and high-pressure crystallography, Proto offers versatile instruments to best suit your application.
Determining the structure of single-crystal materials is imperative to fully understanding their functions, and single-crystal XRD is an established and trusted method for investigating these materials.



Proto's lifetime guarantee means we will continue to support, service, and provide upgrade paths for your instrument for decades to come. Rather than requiring you to buy a brand new system when our product line changes, we are committed to keeping your aging instrument running like new.
