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). For bulk quantities please call 877-260-6039 or send us an email. Borosilicate, 4 mm diameter x approx. 60 cm (2 feet) long. #C2423.........$12.95 / doz.

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).

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 #C2403. Replacement blade for tubing cutter...........$3.49 * 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 |
Important Shipping Note: Small items, such as tubing cutters, stoppers, etc. can almost always ship in the same box with the glass tubing. However, large items such as filter flasks usually have to 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. Example: Suppose you order a 1000-mL filter flask and a bundle of glass tubing. This order will have to ship in two boxes. Your shipping cost will be roughly $7 more than what is listed in your shopping cart. Example 2: Suppose you order two bundles of glass tubing, a pack of slides, and a tubing cutter. All these items will be shipped in a single box that is approximately 28 inches long. Sometimes the smaller items are hard to find amid styrofoam peanuts, but they will be there. Safety Goggles
