Product Description LHe Liquid Helium Storage Dewar/Stainless Steel Self-Pressurized Liquid Tank/Cryogenic Container DewarProduct Description Liquid helium dewar is optimized to minimize the loss of liquid helium in storage, transportation, and distribution.Highefficiency vacuum insulation coating technology, steam cooling multi-cold screen technology and low temperature condensation and adsorption high vacuum technology are adopted to effectively reduce the evaporation rate of liquid helium.Structure Features:1. The liquid helium dewar is made of austenitic stainless steel and has a larger neck, allowing insertion into standard liquid helium lines while eliminating thermal oscillations.It also facilitates the testing of superconducting electrodes and experiments in which the specimen is inserted or immersed in liquid helium;2. No liquid nitrogen sandwich/helium gas circulation pipeline;3. Durable, suitable for truck transportation and frequent daily use;4. Widely used in liquid helium packaging, scientific research and factory liquefaction;5. One piece caster and base.Product Parameters Product ShowUltra Dewar Structure And Detail DisplayProject CaseApplicationsMain applications of liquid helium: cryogenic superconducting and other cryogenic studies (liquid helium is used insuperconducting NMR, spectrometer, magnetoencephalogram, etc.).Widely used in liquid helium packaging, scientific research and factory liquefaction;Physical&Chemical PropertyChemical symbol: HeMolecular weight: 4.003Melting point: -272 oC (25.6bar)Boiling point (101.325kpa) : -268.9 oCLiquid density (101.325 kpa, -269 oC) : 124.8kg/m3Gas density (21.1 oC, 101.325 kpa) : 0.1656 kg/m3Critical temperature: -267.9 oCCritical density: 69.64kg /m3Critical pressure: 227 KpaSpecific volume (21.1 oC, 101.325Kpa) :6.039m3/kgHeat of vaporization (-268.9oC, 101.325 Kpa) : 20.4KJ/kgHeat of vaporization (-268.9oC, 101.325 Kpa) : 20.4KJ/kgCV=3.11KJ/(kg.c)Specific heat ratio: Cp/Cv=1.667Related Products
