Continuous Cold 0.9 K and 1.4 K

Supplier :

The cryostat is supplied in two constant-temperature versions: 1.4 K or 0.9 K, each guaranteed to deliver ≥ 100 mW of cooling power at 1.7 K to the experimental plate.

The closed-cycle 4He phase-separator loop holds the plate within ± 5 mK for day-long runs, providing a flat baseline for low-noise transport or detector work

ABOUT

SYSTEM FEATURES

Truly “hands‑off” continuous cooling

Once it reaches base temperature the fridge keeps itself at 0.9 K or 1.4 K indefinitely, so there are no weekly helium fills or sorption‑pump cycles to plan around

Eight‑to‑ten‑hour turn‑around

Room‑temperature to base in a single work‑day, and you’re back at 3 K in under four hours after a sample swap, which keeps high‑throughput test campaigns moving

>100 mW of cooling headroom

Both versions deliver at least 100 mW at 1.7 K, enough to tolerate thick wiring looms, optical windows or small magnets without the plate drifting

Low‑vibration plate architecture

The cold plate is hung on soft copper braids that decouple the pulse‑tube’s motion, keeping mechanical noise down to levels acceptable for qubits, MKID or AFM heads

Touchscreen + remote control + Python API

One‑button cool‑down on the front panel, but also secure web/mobile access and a scripting interface so you can automate thermal cycles from the lab network

Upgradeable path to millikelvin

Order the 0.9 K version and you can bolt in ZPC’s dilution‑insert kit later, pushing the same chassis to ≈10 mK when your experiments need it

How and Why

Cryogenic System Designs for Quantum Applications

Cryogenic photonic circuits

A continuous 0.9 K bath with optical ports removes the need for a 3He sorption stage during iterative device-foundry runs and lets laser alignment be done through fused-silica windows while the detector stays below its critical temperature

2

Ultra-low-vibration scanning probe microscopy (STM/AFM) near 1 K

ZPC’s braided OFHC heat links and bellows give plate motion in the 10-nm RMS class out of the crate, and an optional pneumatic table brings that below 5 nm for atom-resolved spectroscopy without liquid-helium logistics

3

Muon-spin-rotation and other beam-line sample environments

µSR, neutron, or soft-X-ray instruments often deposit 10–50 mW into the sample platform through photo-heating or eddy-current damping while demanding hours-long constant temperature. A continuous 1 K cryostat with 100 mW overhead can absorb those loads without drifts, and its all-metal vacuum seals survive frequent transport between end-stations

Kinetic-inductance devices and TWPA

TWPAs are typically characterised at 0.8 – 1.2 K, where quasiparticle lifetimes are long enough for high-Q resonances yet the wiring heat load is still manageable. The ZPC 0.9 K version supplies > 100 mW at 1.7 K, so the entire microwave chain (bias tees, isolators, pump lines) can be powered without driving the stage above 1 K, and the sub-5 mK stability keeps gain flat during long calibrations

Rare-earth-ion quantum memories and light–matter interfaces

Narrow homogeneous linewidths (< 100 kHz) and long spin-wave coherence in Yb3+171-doped Y2SiO5 (YSO) and similar crystals improve markedly below ~2 K.
A steady 1 K bath enables 20ms class storage of photonic qubits with minimal spectral diffusion, while optical-access windows in the cryostat let the same sample couple to fibre-coupled cavities or waveguides

Zero Point Cryogenics stems from over two decades of low-temperature research led by Dr. John P. Davis. As a tenured professor at the University of Alberta, Dr. Davis has extensively explored superfluids in the quantum realm and taught thermodynamics, equipping him with deep knowledge of dilution refrigerator technology. His vision was clear: assemble a team capable of redefining the dilution refrigerator market.

Today, Zero Point Cryogenics not only meets the increasing demand for advanced dilution refrigerators essential for quantum

technology but also pioneers innovations that enhance their usability and longevity. Our mission is twofold: empower our partners in industry, academia, and government with superior cryogenic solutions and lead the global market in developing the most dependable and user-friendly cryogenic equipment.

Proudly based in Edmonton, Canada, Zero Point Cryogenics commits to advancing quantum technology research through cryogenics, ensuring our clients can focus on groundbreaking discoveries without compromise.

If Qnity had to pick one company that embodies the phrase “quantum-ready, researcher-friendly, future-proof”, it would be Edmonton-based Zero Point Cryogenics (ZPC). In less than a decade the team has sprinted from university spin-out to internationally recognised innovator, racking up awards and high-profile installations while rewriting the rule-book on sub-Kelvin refrigeration.
Zero Point Cryogenics is the gold-standard for anyone who needs sub-Kelvin performance without dilution-fridge complexity. Their 500 mK continuous cooler is a once-in-a-generation leap.
ZPC customer support carries the enthusiasm of researchers who still remember the painful work-arounds they’ve just made obsolete. If your quantum, sensing or condensed-matter project lives below one kelvin, ZPC is the partner that turns daunting cryogenics into a push-button utility
