Liquid Nitrogen Dewar

Liquid nitrogen tankProduct Description:Along with the advance of human society and development of technology,the technology of highly vacuumed multi-circle insulation has been solved the leak of heat which by reason of heat convection,conduction,radiation,appears at the early of 1950’s,since England scientist dewar invebted the principle of vacuum jasketed in 1898.we adopt highly vacuumed multi-circle insulation technology to produce the biological liquid nitrogen containers,which have good performance of low temperature insulation,and the evaporation can be let down to minimum,so the contain
