DURAN Amber Volumetric Flask 20 mL Class A

DURAN Amber Volumetric Flask 20 mL Class A

The DURAN Amber Volumetric Flask 20 mL Class A (Catalog No. 246761256) provides accurate and light-protected volumetric measurement for analytical and chemical laboratories. It is manufactured from amber borosilicate glass 3.3, which offers exceptional resistance to chemicals and thermal shock while protecting light-sensitive reagents from UV radiation. Moreover, its Class A calibration ensures precision that meets ISO 1042 international standards.

Each flask comes with a Batch Certificate, allowing traceable and verified calibration accuracy. In addition, the white graduation mark provides excellent contrast against the amber background, while the PE plastic stopper ensures a secure seal to prevent evaporation and contamination. Therefore, this flask is ideal for sensitive analytical work requiring both precision and sample protection.

The autoclavable amber glass retains its protective and calibration properties after repeated sterilization. Consequently, it offers durability and reliability for long-term laboratory use. Overall, the DURAN 20 mL Amber Volumetric Flask combines certified accuracy, light protection, and user-friendly design for professional volumetric applications.
