Fast Turnaround Dilution Refrigerator
To create a fast turn-around dilution refrigerator, we revived the form factor of our first cryogen-free dilution refrigerator. The new SD system requires no lab layout or on-site installation, and with the reduced step heat exchanger stage the required amount of helium-3 is only 12 litres, making the system an effective and affordable alternative. SD system typically provides cooling power >250 μW when operated at 100 mK with only 12 litres of helium-3.
Fully Automated Operation
Single push of a button initiated fully automated cool-down sequence from room to base temperature.
Compact and Effective
MXC Flange Diameter: 150 mm | 6″
The experimental space beneath the mixing chamber (no magnet) is 148 mm in diameter and up to 300 mm in height. The height can be easily adapted to suit your experimental requirements. The dilution unit is positioned off-center to provide maximum useful experimental space on all flanges.
Three Access Ports
- Base temperature well below 30 mK
- Fast cool-down: <12 hours to 30 mK
Low Total Cost 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.
