Description
Product Overview
Eisco Labs presents a comprehensive set of 100 precision borosilicate glass capillary tubes designed for high‑performance melting point analysis. Each tube measures 4 inches in length with a 0.05 inch outer diameter, offering a consistent internal volume that supports reproducible results across a wide range of chemical substances. Constructed from premium borosilicate glass, the tubes exhibit exceptional resistance to thermal shock, chemical corrosion, and mechanical stress, making them suitable for demanding laboratory environments. The product is packaged in a sturdy, easy‑dispensing container that releases a single tube at a time, minimizing handling errors and preserving tube integrity. With a strain point of 515 °C, an annealing point of 565 °C, and a softening point of 820 °C, these capillaries maintain dimensional stability even under extreme temperature cycles, ensuring reliable melting point determinations for both research and quality‑control applications.
Usage
These capillary tubes are ideal for laboratories, research facilities, educational institutions, and industrial quality‑control labs where precise melting point measurements are critical. They can be employed in routine analytical procedures, such as determining the purity of organic compounds, assessing polymer thermal properties, and verifying the identity of unknown substances. The tubes are compatible with standard melting point apparatuses, including digital and analog devices, and can be used in both manual and automated testing workflows. Their chemical‑resistant nature allows for testing of acids, bases, solvents, and reactive intermediates without compromising tube integrity. Additionally, the heat‑resistant characteristics enable users to conduct high‑temperature experiments up to 820 °C, expanding the range of materials that can be evaluated. The convenient dispensing container streamlines workflow in busy laboratory settings, reducing the time spent searching for individual tubes and decreasing the risk of cross‑contamination.
