Weighing Bottle, Tall Form

The GISCOM Weighing Bottle (Tall Form) is a high-precision laboratory container designed for accurate weighing of solids, powders, and hygroscopic materials. Manufactured from premium Borosilicate Glass 3.3, it ensures excellent chemical resistance, thermal stability, and dimensional accuracy. This tall-form weighing bottle is essential for analytical laboratories that require consistent, contamination-free weight measurements. Its carefully engineered construction supports high-accuracy workflows across research, industrial, and quality-control environments.

Key Features

• High-purity Borosilicate Glass 3.3: Exceptional thermal, chemical, and mechanical durability.
