YDS-series products are mainly made up of outer shell, inner vessel, neck tube, multi-layer isolating material and canisters. 1.The outer shell and inner vessel are made of the aluminum alloy plate featuring light weight, high cryogenic strength and corrosion resistance. 2.The neck tube is made of glass-fiber reinforced plastics featuring of high mechanical strength and low heat conductivity. 3.The multi-layer insulation is composed of the reflecting screen of aluminum foils with high reflectivity and insulation material with low heat conductivity and low gas-passing speed to reduce heat radiation. 4.The jacket between the outer shell and inner vessel is of high vacuum to prevent thermal convection. Moreover, an adsorbent with a high adsorbing capacity at the cryogenic temperature is used to ensure the long-term stable and reliable performance of the dewar with more than five-year life service.
