Glass vacuum-tube stem blank, formed by centrifugation and annealed. Also available in low-profile slot shape.

To use, heat to working temperature, press against Dumet wire assembly and immediately anneal to produce an UHV-tight electrical feedthrough. Fuse against our matching 30mm envelope to produce a complete vacuum tube.

Our blanks are inspected individually. We guarantee reliable, stress-free fusing against our other soda-lime glass items.
