Glass Tubing
Tubing made of glass, silica, borosilicate, flint glass, or fused quartz, in a variety of diameters and lengths; typically used for passage of heated gases or liquids; includes standard wall tubing and combustion tubes.
Laboratory glass tubing is used in many laboratories or industrial workplaces to connect other items of glassware or equipment and to convey or deliver chemicals, solvents, liquids, gases, and other products. It is normally manufactured from borosilicate glass for the most demanding applications. Borosilicate offers good resistance to heat, thermal shock, and chemicals, with low-leaching extractables, good mechanical strength, and a low coefficient of expansion. Soda lime glass tubing and flint glass tubing have lower softening points and are generally used for less exacting purposes.
Laboratory glass tubing is available in a range of diameters, lengths, and wall thicknesses depending on the intended application. If the lab has the appropriate technical expertise, general-purpose glass tubing can be used as the starting point for the construction of complex pieces of apparatus. It can be cut, bent, or stretched into the requisite conformation after the application of heat.
Lengths of tubing can be held together with clips, clamps, or dedicated adapters for a firm seal. Some tubing systems have ground glass cone and socket joints, available in different sizes and configurations, along with other compatible accessories such as stopcocks and splash-heads.
Laboratory Glass Tubing Has a Variety of Applications:
• In the chemistry laboratory for organic synthesis, fractionation, distillation, or titration
• In the biological science laboratory to set up simple chromatographic or filter columns
• In classrooms and other education environments, for example gas delivery and collection experiments
• In industrial chemical, pharmaceutical, or biotech laboratories, for manufacturing pipelines, test rigs, or scale-up rigs
