One 29" length of soda-lime glass tubing.

Tubes are guaranteed to fuse reliably (without leaving stresses after annealing) with the other soda-lime glass tubing we carry. Our Dumet wire also provides a reliable glass-to-metal seal against this glass.

We can also provide glass tubing in arbitrary lengths, as well as custom soda-lime or borosilicate glass items (please inquire).

Tubes are packed securely and shipped in thick kraft mailing tubes. We will combine shipping for multiple lengths and diameters in the most secure and economical way.
