XLD Series

For the Most Demanding Experiments.

Standard range models BF-XLD400 and the new BF-XLD1000.

Unique Wiring Capabilities

The standard BF-XLD can accommodate over 200 factory installed semi-rigid RF coaxial lines still reaching base temperature of ~10mK.

Extensive. Heavy Duty.

Six LOS Access Ports

All line-of-sight ports reach from room temperature to mixing chamber.

  • 6 x K-100

Vast Experimental Space

MXC Flange Diameter: 500mm / 20″

Off-center placed dilution unit maximizes useful space on all flanges. Open design permits easy experimental access without being obscured by heat exchangers or system support structure.


Fully Automated Operation

Single push of a button initiated fully automated cool-down sequence from room to base temperature.


Superior Performance

  • Base temperature well below 10mK
  • Cooling power: > 15µW at 20mK with only 18L of He-3
  • Extremely fast cool-down: < 24 hours to 10mK

High Value of Ownership

Oil-free pumps and compressors in gas handling unit guarantee minimal maintenance requirements with service interval up to 3 years. The systems employ only high quality components such as Pfeiffer Vacuum pumps and pressure sensors, VAT vacuum valves and bellows.

Proven Technology

The BF-XLD systems are built using the same dilution unit and gas handling system as our most sold model, the BF-LD series.

Worldwide Recognition

Over 100 leading research institutions and companies use BlueFors systems in the fields of quantum computing, nuclear physics, astronomy and basic sciences.

Special Versions

BF-XLD-4K and BF-XLD-HE

Entry level systems provide a BF-XLD cryostat without dilution unit. Allows experiments down to 3K or 0.5K with the possibility of upgrading to dilution refrigerator at any later stage. All standard options such as magnets, wiring and vibration isolation are available. Upgrading to full BF-XLD dilution refrigerator takes only 3-4 days at site of installation.

BF-XLD1000

For demanding experiments which require the highest cooling powers, introducing the BF-XLD1000. Base temperature is typically below 7mK and cooling power above 30µW at 20mK and over 1mW at 100mK.
