500ml PFA Volumetric Flask

Brand: Nanjing Binzhenghong

Model: NJ-ZH

1. Product name: PFA volumetric flask

2. Material: Imported experimental grade PFA raw material

3. Mouth structure: screw cap design, screw cap seal to prevent sample contamination

4. Appearance: Highly transparent, convenient for constant volume

5. Ring scale mark calibration: "In"

6. Calibration tolerance: the scale line on each PFA volumetric flask is accurately weighed and marked with a one-thousandth electronic balance, A-level tolerance, in line with DIN EN ISO 1042

7. PFA material has outstanding chemical corrosion resistance, and can be used for strong oxidants, high-concentration acids and bases, hydrocarbons and ketones and other strong corrosives and organic solvents

8. With laser engraved scale line, the line is clear, easy to watch the liquid level, and accurately determine the volume

9. Due to the stability of the PFA material, as a constant volume instrument, it has good dimensional stability. Even at 121 °C, it will not cause changes in calibration tolerances (in order to protect the ring scale mark, the cleaning temperature should be lower than 60 °C.)

10. High thermal stability, can withstand -200 ℃ to +260 ℃ (as a constant vessel, we suggest customers not to use it directly as a heating vessel)

11. PFA material has hydrophobicity and smooth surface, which will not produce cross-contamination and affect sample data
