- Material: Constructed from Corning Pyrex® Borosilicate Glass (Type 7740), which offers exceptional chemical resistance, high thermal stability, and resistance to thermal shock.
- Design Pattern: Typically follows the Gay-Lussac pattern, featuring a pear-shaped or cylindrical body with a flat bottom to prevent spills.
- Precision Stopper: Equipped with a ground glass capillary stopper. The fine bore (perforation) allows air and excess liquid to escape, ensuring a constant, precisely defined volume when the bottle is filled.
- Calibration: Available in both “unadjusted” (for user calibration) and “adjusted” versions. Adjusted versions are often calibrated at 20°C and may include a unique serial number on both the bottle and stopper to ensure they remain a matched set for accuracy.
- Specifications:
- Capacity: 50 mL.
- Approximate Dimensions: Roughly 4 inches (102 mm) tall with the stopper and 2 inches (51 mm) in diameter.
- Weight Traceability: Some models are traceable to NIST standards for professional quality control.
