Premium 25ml Volumetric Flask with Glass Stopper – High-Precision Borosilicate Measuring Flask for Chemistry Labs (Pack of 2)

Master your laboratory measurements with our 25ml Volumetric Flask set. This professional-grade measuring flask is engineered from high-quality expansion borosilicate glass, ensuring superior resistance to thermal shock and chemical corrosion. Designed with a signature long neck and a single graduation mark, this volumetric flask allows for the ultra-precise preparation of standard solutions. Each flask comes equipped with a ground-glass stopper to provide an airtight, leak-proof seal, making it an indispensable tool for any chemistry lab or scientific research facility.

Key Features

• High-Precision Calibration: Each volumetric flask is individually calibrated to contain exactly 25ml at $20\text{°C}$, ensuring maximum accuracy for titration and analytical chemistry.

• Premium Borosilicate Glass: Crafted from heavy-duty, heat-resistant borosilicate glass, this measuring flask is built to withstand rigorous laboratory use and frequent cleaning.

• Airtight Glass Stopper: Includes a precision-ground glass stopper that prevents evaporation and contamination of sensitive chemical reagents.

• Long Neck Design: The narrow long neck minimizes surface area errors, allowing for a more precise reading of the meniscus during solution preparation.

• Value Pack of 2: This set provides two high-quality flasks, perfect for simultaneous experiments or as essential backups in a busy chemistry lab.
