PFA volumetric flask
The features of PFA volumetric flask:
1. Made of high-purity imported experimental-grade PFA material
3. Nut mouth design, screw cap seal, prevent sample contamination
4. Highly transparent, convenient for constant volume
5. Circular scale mark calibration: "In"
6. Class A tolerances in accordance with DIN EN ISO 1042
7. Good chemical resistance
8. With laser engraving scale line, the scale line is clear, easy to see the liquid level, accurate volume
9. Has good dimensional stability
10. High thermal stability, can withstand -200 ℃ to +260 ℃ (but it is recommended that customers do not use it directly as a heating vessel)
11. PFA material has super-hydrophobicity, smooth surface, no cross-contamination
