Volumetric Flask – Class A, PE Stopper, Batch Certified, ISO 1042 Compliant

Product Overview

This 25 mL Class A volumetric flask is engineered for high-precision volumetric measurements in analytical, pharmaceutical, and research laboratories. The flask is manufactured from borosilicate glass 3.3, ensuring superior thermal resistance, chemical stability, and mechanical durability under routine laboratory conditions.

The flask complies with ISO 1042 standards and is supplied with a batch calibration certificate, ensuring traceability and quality assurance across production lots. Its blue printed calibration mark is permanently fused onto the glass and resistant to chemicals, abrasion, and standard laboratory cleaning processes.

The narrow-neck design and a precision-etched calibration line allow for highly accurate liquid volume measurement, while the accompanying polyethylene (PE) stopper ensures a secure seal without chemical interference, making it suitable for temporary storage and solution preparation. This flask is especially suitable for quantitative volumetric analysis where high measurement fidelity is essential.
