Pyrex Glass Tubing

The most common type of Pyrex glass tubing is standard wall. The cylindrical tubes are made from borosilicate glass. The hollow tubes can be used in variety of applications, including laboratory glassware, pharmaceutical packaging and even lighting applications. Without question, standard wall Pyrex glass tubing is a versatile product.

Borosilicate glass features silica and boron trioxide as the main compounds. The glass, and subsequent tubes, are therefore highly resistant to both heat and chemicals. The glass also features a high mechanical strength, and can measurably resist increased pressure and stress. These properties make the tubing ideal for the conditions often experienced in laboratory work.

Modification is often required on Pyrex glass tubing prior to use. Although for some applications the tubing can be used straight away, that’s not always the case for laboratory work. The tubing usually needs to be cut or bent into various shapes. Most often, glass cutters are used to cut the tubing into even, smaller pieces. Rough edges are smoothed down through the use of applied heat. And by heating the Pyrex glass tubing to a red flame over a Bunson burner, the glass will become malleable.

Power and telecommunication companies often us both medium and heavy wall Pyrex glass tubing for protection purposes. Although this kind of glass is also used in a laboratory, its properties make it ideal for cable repair and protection. Borosilicate glass offers superior protection from corrosion because of its high mechanical strength. And its moisture-barrier allows for added protection for power wires and cables that need to be buried underground.

In addition to special wall Pyrex glass tubing, Mac Bic also stocks capillary tubing. These small tubes are very thin and, as their name suggests, are often used to collect blood samples.
