This Sodium Metal Element Sample contains genuine 99.9% pure sodium (Na), representing Element 11 of the periodic table. Each specimen is packaged in a clear 1 dram glass vial and offered in two size options: 0.5 gram and 1 gram, allowing collectors and educators to choose the quantity that best fits their needs.

Each vial is fitted with a custom-designed protective vial sleeve created specifically to help safeguard the glass vial during transport and routine handling. These sleeves help reduce the risk of breakage while maintaining a clean and professional presentation suitable for element collections and educational environments. These sodium specimens are ideal for periodic table collections, chemistry education, science demonstrations, and element enthusiasts seeking a genuine sample of this alkali metal.
