Bottles(Weighing ASTM)

Weighing Bottles (ASTM Standard) are specialized laboratory glassware used for precise weighing of solid or powdered substances. These bottles are manufactured to conform to ASTM (American Society for Testing and Materials) specifications, ensuring uniformity, high precision, and chemical resistance suitable for analytical and gravimetric applications. These bottles are typically made of borosilicate glass, offering excellent thermal and chemical stability, and are available in various shapes, including cylindrical, flat-bottom, and low or tall forms. A well-fitting ground glass stopper or cap is included to prevent moisture absorption and contamination of hygroscopic or volatile substances during weighing. Some designs feature flared rims or ground joints to facilitate easy handling and prevent sample loss. The ASTM-compliant weighing bottles are widely used in analytical chemistry, pharmaceutical labs, and research settings that require high accuracy in mass determination.
