Ürün Açıklaması

Reliable High Purity Liquid Helium Dewar For Magnetic Resonance Imaging

Product Description

 

Liquid helium dewar is optimized to minimize the loss of liquid helium in storage, transportation, and distribution.High
efficiency 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.
