Find all the glass, rubber, or plastic tubing that you need for your science experiments.
Glass tubing is made from carefully-cut pieces of hollow tubes and is used frequently in chemistry experiments. Tubing is often inserted into rubber stoppers with one or two holes for ventilation or vapor passage. Putting tubing in rubber stoppers can be difficult; please handle tubing carefully and use proper safety equipment when inserting tubing into stoppers. Check out a wide selection of glass tubing along with glass cutters to cut tubing to size.
The 5 mm glass tubing fits the holes in all of our rubber stoppers.
