Specific Gravity Bottle Gay-Lussac

Precision glass pycnometer used in laboratories to determine the density or specific gravity of liquids and fine solids. It features a capillary vent stopper that allows excess liquid to escape, ensuring a highly accurate and repeatable volume.

• Material: High-quality Borosilicate Glass 3.3, which provides excellent chemical resistance and low thermal expansion to minimize measurement errors due to temperature changes.
• Stopper: Ground-glass capillary stopper with a fine bore; calibrated versions often have stoppers and bottles matched with unique identification numbers.
• Design: Pear-shaped or cylindrical with a flat bottom for stability and to prevent spills.
