  • This tube has aquadag coated thin mica window at the end of the tube opposite the termination. This window is for detection of alpha and beta particles. The window will appear to be slightly concave as the pressure in the tube is less than atmospheric (~0.1 Atm). The window is extremely fragile, touching it will likely convert your tube to an ornament, wasting your $94!

No public wish lists :(
