Key Features

• Pre-Sealed Convenience: One end is professionally flame-sealed, eliminating the need for manual sealing and reducing the risk of sample contamination or loss.

• Rapid Heat Conduction: The thin-walled borosilicate glass ensures that the sample reaches the furnace temperature quickly and accurately.

• High Optical Clarity: Transparent glass allows for precise observation of the transition from solid to liquid phase under magnification.

• Uniform Dimensions: Meticulously manufactured for consistent internal and external diameters, ensuring repeatable results across all 100 tubes.

• Chemical Resistance: Resistant to a wide range of organic and inorganic chemicals, preventing glass-sample interactions during heating.

Common Applications

• Analytical Chemistry: Determining the melting point of crystalline solids to verify identity and purity.

• Pharmaceutical Testing: Essential for quality control of raw materials and active ingredients.

• Research & Development: Characterizing new synthetic compounds in organic chemistry labs.

• Academic Labs: A fundamental consumable for teaching physical properties in high school and university science courses.
