Borosilicate Glass Tubing: 5mm(OD) x 12 Inches: Pk 5 PC

Glass tubing hasn't changed since I was a nine-year old - at leastas far as I can tell.This tubing behaved just as I expected it to; easy to heat and bendinto service of what I had in mind.It cam perfectly packaged and arrived sooner than expected.

These are working great for me, I was able to shape them easily with a bernzomatic heating torch on low. They seem extremely strong as I used quite a bit of pressure to insert them into a rubber stopper.

Internal dimensions were all different sizes. I could not use these..

These tubes work really well for the small amount of chemistry I do in my home darkroom. Using a plumbers torch you can easily bend these into your desired shapes.

There is not much to say. They are glass and they are tubes, if they had been anything else... Just getting them here unbroken is a miracle.

this glass tubing is great for making shaft bearings for experiments and crafts that need low friction to conserve energy.

work out great for water glass for Aster steam Engine

good for stir rods or siphoning
