LD250 Dilution Refrigerator Measurement System
Model: LD250
Manufacturer: Bluefors - Finland
Origin: Finland
Designed to provide an ultra-low temperature environment (below 10 mK) for quantum experiments and low-temperature physics research, the LD250 system stands out with its rapid cooling capability, automated operation, and open design for easy access to the experimental space. It is optimized to deliver high cooling power, making it suitable for experiments requiring large sample spaces and robust cooling performance.
Rapid Cooling: ~24 hours from room temperature to base temperature.
Reliability: No soft solder joints in the helium mixture circuit; fully welded heat exchanger.
No Internal Vacuum Can Required: Sealed joint at room temperature.
No 1-K Stage Required.
Automation: One-button cooling operation.
Remote/Manual Control.
Automatic Recovery After Power Loss.
Lightweight: Vacuum enclosure and radiation shield controlled by a single person.
Low Vibration: Mechanically isolated pulse tube.
Extended Operation: Up to 2 months without nitrogen trap.
Oil-Free: Oil-free pumps and compressors.
No Risk of Rupture: Non-diaphragm circulation compressor with a ~3-year maintenance cycle.
