Tubing, Glass, Borosilicate - 4, 5, 6, and 7 tube diameters available. Borosilicate glass is superior to ordinary flint glass in both heat and corrosion resistance. It can be softened for heat-bending in a propane or Bunsen burner flame.
The 5 mm glass tubing is the most popular size and will
fit the common sizes of pre-bored stoppers (#1 through #6).4, 5, 6, and 7 mm tubing comes in bundles of 12 pcs. each. The length of each piece is approximately 24 inches (60 cm). Borosilicate, 4 mm diameter x approx. 60 cm (2 feet) long. #C2423.........$12.95 / doz.
Outside Diameter ca.
4.0 mm
Wall thickness ca.
0.85 mmShip wt. approx. 1 lb. Borosilicate, 5 mm diameter x approx. 60 cm (2 feet) long. #C2424-DZ..........$14.95 / doz. 5 mm is the popular size that fits most common 1- and 2-hole stoppers. IMPORTANT note about the 5mm tubing: The current batch we have varies between ca. 4.6 and 5.2 mm. Wall thickness is typically 1.1 to 1.2 mm. This is general chemistry tubing; it is not suitable for precise engineering applications. A bundle of tubing will contain whatever size deviation is in the batch. Borosilicate, 6 mm diameter x approx. 60 cm (2 feet) long. #C2425.........$16.95 / doz.
Outside Diameter ca. 6.0 mm
Wall Thickness ca. 1.0 mm 6 mm tubing is a little too big for the common sizes of pre-bored stoppers we have in stock, although some customers prefer it when a tighter fit is required in the stopper holes (wear heavy gloves and safety goggles when pushing tubing through a stopper hole; use soapy water to reduce the friction). Ship wt. approx. 1 lb. Borosilicate, 7 mm diameter x ca. 60 cm (2 feet) long #C2426..........$18.95 / doz
Outside dia. ca. 7.0 mm
Wall thickness ca. 1.0 mm7 mm and up will not fit in the standard bored holes of most stoppers. You must enlarge the stopper holes by hand with the aid of a cork borer or a drill. Larger Sizes of tubing are available in Flint Glass. Tubing Cutter
Ship. wt. 1/2 lb. #C2400. Glass tube cutter..............$11.99 * Never heat a tube that's been sealed at both ends; it could explode and send glass fragments everywhere. There must always be some vent for expanding gases to escape. Catalog Main page Important: Wear eye protection while working with glass tubing. Keep bystanders away. To lessen the danger of painful accidents, wear heavy canvas or leather gloves while heat-bending glass tubing or trying to insert it through a stopper. Copyright |
Shipping Note: Small items (e.g., tubing cutters, stoppers) usually ship in the same box with the glass tubing. Larger items (e.g., filter flasks) usually must ship in a separate box, unless we use an oversize package. Multiple boxes or oversize packages can incur additional shipping charges that are not listed in your shopping cart. (If you order $50 or more of merchandise, we'll absorb the extra shipping cost) Safety Goggles
