The DC (formerly HPD) Model 103 Rainier ADR Cryostat
Small, Cryogen-Free ADR Cryostat
The DC (formerly HPD) Rainier Model 103 adiabatic demagnetization refrigerator (ADR) is a compact cryostat that provides a surprisingly large experimental space: 26 cm diameter by 25 cm tall. Danaher Cryo's attention to detail provides many high-quality cryogenic features, including cool down from 300 K to 3 K in just 15 hours, a vibration minimizing design, and 250 hour no-load regulation at 100 mK. The Rainier 103 can also be reconfigured for your specific project.
Model 103 Rainier Deep Dive
This system uses a two-stage ADR to reach temperatures as low as 30 mK. An ADR operates by subjecting a salt crystal to strong magnetic fields. In these different states, the salt crystal will either absorb or dump thermal energy. This is used to shuttle heat away from the sample stage achieving mK temperatures. Because of the nature of this process, only a certain amount of heat can be absorbed before the crystal must be warmed up and regenerated.
Designed with customization in mind, the Model 103 Rainier is fitted with two large electrical breadboards at both 4 K and 50 K. Additionally, there are multiple customizable feedthroughs in each stage plate. If you are constrained by cooldown times, the Model 103 can support Rapid Cool liquid nitrogen heat exchangers. It is a robust “turn-key” mK alternative to dilution refrigerators.
Applications: Astronomy, Spin QC, Photonic QC, Material Characterization, Condensed Matter Physics

Accessory Add-Ons
Custom Service Stand
The top plate of the cryostat has mounting provisions that allow the cryostat to be attached to the service stand. This mount consists of a plate and ball attached to rods extending from the top plate of the vacuum jacket. The Service Stand attaches to the ball for lifting. Three jack screws on the top plate of the Service Stand allow for tilt adjustment and for locking the cryostat. The ball allows for rotating, and some slight swinging, of the cryostat. The service stand has casters to allow it to be rolled into position for attaching the cryostat.
The Service Stand has a vertical height adjustment capability that allows for placing the cryostat on a bench or other support structure. The vertical travel is approximately 76 cm.
