New DOMO Sample Dewar Lid

We’ve installed a sweet new blue anodized aluminum air dam on the pneumatic lid for the DOMO sample dewar (with color coordinated electric blue CPU fans). The air dam helps to draw off frozen ice crystals from the air above the liquid nitrogen when the dewar lid is open. This will hopefully prevent the ice from falling into the LN2 and contaminating it. If it doesn’t work at least it looks cool.
