The modular Cryofree® ProteoxMX dilution refrigerator delivers greater experimental capacity and adaptability. Versatile dilution refrigerator for ULT experiments. Base temperature of < 10 mK, cooling power of > 12 µW at 20 mK and 360 mm mixing chamber plate diameter.
Dry systems do not require the use of cryogenic liquids to provide the 4 K environment. Instead, pulse tube refrigerators are used. These enable push-button operation, can reduce the cost of ownership, and negate the need for a helium liquefier.
Our Cryofree® (cryogen free) range of products provides the user with much more experimental space and a larger sample plate, due to not needing a dewar surrounding the system containing the liquid helium for cooling. Mechanical vibrations from the pulse tube refrigerator are significantly reduced using a comprehensive range of vibration isolation techniques.
Integrate microwave lines and signal conditioning hardware on the Secondary Insert for superconducting qubit development.
Integrate microwave wiring, cold electronics and superconducting magnets for spin qubit development.
Superconducting magnets and ultra low temperatures enable hall effect and quantum hall effect transport measurements.

Ideal for a multi-user or multi-experiment setting, or future-proofing the system. Side loading Secondary Inserts can be exchanged between Proteox systems enabling experiments to be set up on a workbench prior to exchange. This is a significant advantage for optical experiments where alignment of components can be performed outside of the system.
Utilise a custom Secondary Insert for an optimised experiment, ready to run on system arrival by incorporating cold electronics such as circulators and amplifiers, directly during manufacture. All mounted hardware and components are factory installed.
Moving beyond standard access ports, the Secondary Insert can accommodate full experimental set-ups, including DC wiring, coaxial wiring and signal conditioning components.
| ISO100‑2 |
A standard configuration of 2 x ISO100 ports, with multiple ISO100 options to provide experimental wiring.

| BLL-60 |
A Secondary Insert for fast sample exchange with a cold finger assembly to suit the 60 mm sample exchange puck. |
| BLL-72 |
A Secondary Insert for fast sample exchange with a cold finger assembly to suit the 72 mm sample exchange puck. |
| Optional Blank Plates Instead Of SI |
Blanking plate with tapped M3 grid array option if SI not required. |
| Custom Secondary Insert Option |
Customise an entire Secondary Insert for your specific experimental needs. |
Our patented bottom loader and active gas gap heat switch technology enable fast sample turnaround times with sample puck cooldown times in less than 8 hours, particularly suited to magnet systems and for qubit screening. For the ProteoxMX, the sample loader is integrated onto a Secondary Insert, including hermetic feedthroughs and thermalisation hardware for provision of experimental wiring.
