Dilution Fridge Model L

Supplier :

Benefit from the industry’s longest four-year warranty, reducing lifecycle costs and inspiring confidence in projects

Wherever the experiment calls for large cold real estate, hands off months long stability, low vibration/noise, and a tight lab footprint, the Model L offers tangible advantages over most mid-size dilution refrigerators presently on the market

ABOUT

SYSTEM FEATURES

Optimized experimental space

A generous 340 mm sample plate sits inside an overall footprint of roughly 1.8 m², so you get plenty of experimental space without eating up the lab floor.

All-metal, solder-free joint philosophy

This minimises out-gassing and indium creep, lowers magnetic contamination, and simplifies bake-out, a design choice most large vendors reserve for custom “ultra-low-noise” builds.

One-button touchscreen + open Python API

Trainees can run the fridge safely on day one, while power users script automated cooldowns, logging and device bias ramps.

Best-in-class warranty and service envelope

48-month parts warranty! Longest baseline cover in the dilution fridge market.
Lowers the cost of risk, common suppliers stop at 24–36 months.

Remote Operation

Touchscreen interface with VPN access lets researchers operate, diagnose, and tweak cooldowns from anywhere remotely.

Extended-life, LN₂-free cold trap

The extended-life cold trap, integrated into the 45 K plate, eliminates the need for frequent monitoring and refilling of external liquid nitrogen dewars, making maintenance less of a hassle

How and Why

Cryogenic System Designs for Quantum Applications

Superconducting-qubit processors & circuit-QED testbeds

340 mm×245 mm stage with 250–400 µW @ 100 mK gives space and power, all-metal seals cut magnetic/electrical noise and touch-screen + VPN lets engineers reboot or diagnose remotely overnight

2

Semiconductor spin-qubit arrays

Vector magnet-ready design and the wide plate leave clearance on sample and RF–DC filters, galvanic isolation suppresses charge noise that limits spin-qubit fidelity.

3

Topological/Majorana-qubit prototypes

Magnet compatibility, integrated cryogen-free cold trap for month long holds, and an industry leading 48-month warranty support long, iterative development cycles.

Quantum opto-nanomechanic

Optional enhanced vibration-isolation kit plus standard free-space and fibre ports, large plate lets lasers, cavities and microwave components share the cold space

Low-temperature fundamental condensed-matter physics

< 10 mK base with 250–400 µW at 100 mK delivers both deep cooldowns and the overhead needed for high-field, high-heat-load sample stages.
Galvanic isolation and roomy wiring ports support multi-axis vector magnets and dilution-compatible scanning probes (STM, NV tips)

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.

Model L Dilution Refrigerator

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
