Is borosilicate glass safe for hot drinks?

Yes. Borosilicate tolerates heat and thermal shock much better than ordinary glass, so hot tea or coffee is fine. Avoid sudden extreme temperature changes anyway.

Can I cut these tubes to length?

Yes. A glass cutter or a small file score plus a clean snap works on thin borosilicate. Flame-polish the cut end so it is smooth to the mouth.

Are they suitable for lab use?

For simple mixing, transfer or hobby work, yes. They are not calibrated or thick-walled, so skip them for pressure, vacuum or precise measurement.

What is the inside diameter?

With a 1.5 mm wall on a 200 mm tube, the bore is narrow, roughly a few millimeters. That suits straws and thin craft work but not thick smoothies.

Can I put them in the dishwasher?

Hand washing is safer. The thin wall and long shape make them prone to knocking against racks and other items.

Our take on the Unique Bargains Glass Tubes Borosilicate Long Glass Pipes Blowing Tubes Blue

These are straight borosilicate glass tubes, 200 mm long with a 1.5 mm wall, in blue. Borosilicate handles heat and thermal shock far better than ordinary soda-lime glass, so the tubes suit lab work, craft and glassblowing practice, and food or drink use. The thin wall and narrow bore make them light and easy to cut or flame-polish, but they are fragile in transit and not a substitute for thick-walled lab tubing under pressure. Buyers pick them as inexpensive, reusable glass straws and craft blanks rather than as precision labware.
