What if… you could have an ultra-low noise LT (7 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 7 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.

PanScan-Freedom LT incorporates RHK's purpose-built hardware, including the groundbreaking R9 control electronics, for lowest noise, highest performance, and industry leading cryogen-free low temperature performance.
Uniquely designed foreasy adaptation, PanScan-Freedom LT can also integrate with existing chambers to provide an affordable, small footprint LT UHV SPM station on other analysis or process instruments already in place in a laboratory. The clever design of the closed cycle module also provides an easy upgrade path for existing PanScan systems, protecting the customer's investment in their research. Innovation in every nanometer from the industry's most experienced designers. Not just remarkable...revolutionary.
