Cryogenics & Magnetics16www.lotoriel.co.ukCryostatsHPD CryosatsHPD offers a large variety of cryostats which can be con!gured individually. Depending on the required temperature and cooling power, different combinations of cryostats like pulse tube , ADR, or dilution refrigerator may be chosen. Also the integration of various contacting possibilities like electrical feedthroughs, microwave conductors or !bres is offered.Several experiments can be installed at the same time at different temperature stages of the$cryostat.Cryostat Types????????Adiabatic Demagnetisation Refrigerator (ADR)????????Pulse tube coolers????????Wet and dry dilution refrigerators????????Compatible with Janis or Leiden DR insertsModel Number101102103104105106Name MATTERHORN DENALI RAINIER OLYMPUS ANNAPURNA SHASTA Vacuum Jacket Size 21.3" Diameter 46.9" Tall 13" X 8.7" 25.9" Tall 13.9" Diameter 27.1" Tall 21.7" Diameter 43.2" Tall 21.7" Diameter 43.2" Tall 17.3" Diameter 25.6" Tall Experimental Volume 16.5" Diameter 7.6" Tall 9.5" X 6" X 5.5" 10.2" Diameter 10" Tall 17.4" Diameter 23.7" Tall 16.5" Diameter 7.6" Tall 13.3" Diameter 8.1" Tall 1st Stage Pulse Tube Cooling Power NA 25 W @ 55 K 25 W @ 55 K 35 W @ 45 K 40$W @ 45 K 40 W @ 45 K 25 W @ 55 K 35 W @ 45 K 40 W @ 45K 2nd Stage Pulse Tube Cooling Power NA 0.7 W @ 4.2 K 0.7 W @ 4.2 K 1 W @ 4.2 K 1.5 W @ 4.2 K 1.5 W @ 4.2 K 0.7 W @ 4.2K 1.5 W @ 4.2 K 1 W @ 4.2 K
