cryogenic system highlights
closed-cycle & turn-key
Our cryogenic systems do not require liquid cryogens to operate. They can operate on the push of a button. They use commercially available cryocoolers to achieve temperatures below 4 Kelvin. We have plenty of customers who have no prior experience with cryogenics or even vacuum pumps.
sub-Kelvin operation
For customers that require sub-Kelvin operation, we integrate our custom-designed helium sorption fridge to a 4 Kelvin cryocooler. Helium sorption fridges use the principle of evaporative cooling to provide a temperature of ~ 800 milliKelvin. Our sorption fridges have no moving parts.
modular & future-proof
Our systems are "turn-key", but we don't go as far as making them "black boxes": you will learn how they work, and have the ability to open them up so you can add/remove detectors & electronics, and perform basic troubleshooting without having to ship them back to us.
temperature stability
We also make cryogenic systems that provide ultra-stable operating temperatures (typically ~ 3 mK peak to peak) with a minimal impact on the cooling capacity of the cryocooler.
compact & cost-effective
Our cryostats are a cost-effective alternative to other technologies like ADRs or dilution fridges in situations where temperatures in the 0.8 K - 1 K range are desired for an experiment. They can be fit on a table-top or in a portable server rack.
custom built for your experiments
We customize our systems all the time. They can be perfectly tailored for superconducting detectors (such as SNSPDs), cryogenic electronics, and Josephson junction arrays.
cryostat models
We offer three main models, which can be customized to your requirements.
cryospot 4
compact yet versatile
< 4 K and < 800 mK
This system is ideal when vibrations from the cryocooler will not impact your experiment. It can be equipped with Gifford-McMahon (GM) cryocoolers with cooling capacities up to 0.5 W @ 4 K. It can host up to 32 SNSPDs or be used for other experiments requiring sub-Kelvin temperatures.
overview
- compact 6" OD cryostat
- 8x feedthrough ports (5 are configurable)
- typical base temperature: < 2.7 K

cryospot 4ts New
extreme temperature stability
< 3 mK peak to peak @ 4 K
This system offers excellent temperature stability with a minimal loss in cooling capacity of the cryocooler. It can be equipped with Gifford-McMahon (GM) cryocoolers with cooling capacities up to 0.5 W @ 4 K. It is typically used for experiments involving Josephson junctions.
