Description:

The JOINTED Test Tube (15mL, 125mm Length) is precision-crafted from high-quality borosilicate glass, offering superior thermal resistance, chemical durability, and optical clarity for advanced laboratory work. Featuring a standard ground glass socket (14/23), this test tube enables seamless integration with compatible jointed glassware, making it ideal for controlled reactions, distillation setups, or sample containment within reflux systems. The robust borosilicate construction resists thermal shock, allowing use across a wide temperature range without compromise to structural integrity. Its smooth cylindrical design supports uniform heating and clean observation of contents, while the 125mm length provides ample capacity for various experimental volumes. Interchangeable and reusable, this tube is a reliable component for academic research, pharmaceutical processes, and industrial chemical handling. Sold individually, it offers a premium, scalable solution for precision lab setups seeking compliance and longevity.
