New Standard in cryogen-free LT SPM Systems for Nanoscience.

PanScan Freedom Overview

What if… you could have an ultra-low noise LT (9 K chilled tip/sample) STM- AFM/qPlus System in your lab that never needs liquid cryogens –even running 24 hours a day producing atomic resolution images and lengthy, sophisticated STS data?

That would mean your research is Cryogen cost-free, Interruption-free, and Hassle-free. You’d never waste time trying to source LHe or waste money paying upward-spiraling prices. No more interrupted or delayed experiments waiting for cryogen supplies. The hassles and real risks of handling and changing dewars would disappear. You’d spend more time on research. Achieve better results faster.

RHK’s PanScan Freedom delivers all that and more. All the advantages of LT. None of the constraints. Proven atomic resolution 9 K – 400 K. Peer-reviewed published results. XY drift achievable as low as 0.2Å/hour, and Z drift as low as 0.2Å/day. Dedicated STM/STS and also qPlus-AFM. No special Lab set-up or ceiling heights. Straightforward design, easy to operate.

Meet RHK’s award-winning PanScan Freedom, the world’s first closed-cycle cryogen-free system for stable low temperature performance in a surprisingly compact, simple, and affordable package. PanScan Freedom enables you to explore tomorrow’s materials and make discoveries that will keep your laboratory first in science.

Freedom has proven atomic resolution results on materials from crystalline metals to carbon nanotubes, plus world-class low-noise, low-drift STS, without consuming a drop of LHe.

Free Yourself.

  • AVS2014

    Even noisy environments do not degrade performance, which was proven running the PanScan Freedom live on the exhibition floor during AVS 2014, APS 2015, DPG 2015, AVS 2015, and APS 2016.

  • APS2015

    Another amazing repeat performance. UHV LT atomic resolution in noisy crowded conditions live on the exhibit floor, with no added vibration isolation.

  • DPG2015

    The PanScan Freedom systems performed flawlessly at each of these venues. Atomic resolution data was routinely demonstrated, independent of environmental noise and crowds of people.

  • AVS2015

    Seeing is Believing. RHK proves Freedom performance again. RHK's advances and design breakthroughs eliminate the noise and vibration associated with prior CC Cryostats.

  • APS2016

    In addition, showing the real-world performance of the instrument as opposed to a few “hero” image data examples, is a much more powerful demonstration of the PanScan Freedom’s capabilities.
