There are four Teflon® lined bushings that guide sensors into the gold plated equalization block. It is completely immersed in the cryogenic liquid contained within a super-insulated vacuum dewar. The Cryo-Cal®'s gold plated equalization block greatly reduces corrosion and oxidation and contributes to the ± 0.002 K stability and uniformity of the whole system.
