## Overview

This pack of Borosilicate Glass Tubing features five 12-inch tubes with a 5mm outer diameter, designed for high durability and temperature resistance, making them perfect for a variety of professional and creative applications.

## Description

Glass tubing is most often used in laboratories, but is also very popular for creating homemade Hummingbird feeders. This tubing is of a low expansion borosilicate composition with high chemical resistance, making it the most popular type of glass in the world for laboratory use. It meets all U.S. Pharmacopoeia specifications for type 1A glass. Borosilicate glass is simply the generic form of the better known heat resistant glass brands Pyrex, Corning, Simax, Kimax and others.  In order to be bent, the tubing has to be heated until it glows a faint red color. Heating should be with a propane or natural gas burner similar to a plumbing torch or our propane Bunsen burner. Propane can be purchased at a local hardware store.

- 12 inches in length
- O.D. Variance - 0.3mm

*by I***Z on Reviewed in the United States 🇺🇸 on February 8, 2016*

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.
