Product Introduction

PFAvolumetric flask

1Product Name:PFA volumetric flask

2Material: High purity imported experimental gradePFA raw materials

3. Mouth structure: Nut design, threaded cover sealing to prevent sample contamination

4. Appearance: Highly transparent, convenient for sizing

5. Calibration of circular scale identification: "In"

6、Calibration tolerance:each onePFAThe scale lines on the volumetric flask are measured and marked using a one thousandth electronic balance，A-class tolerance,conform to DIN EN ISO 1042

7. PFA material has chemical corrosion resistance and can be used for various strong corrosives such as strong oxidants, high concentrations of acids and bases, hydrocarbons and ketones, as well as organic solvents

8. With laser engraved scale lines, the lines are clear and easy to observe the liquid level, accurately determining the volume

9. Due to the stability of PFA material, as a constant volume instrument, it has good dimensional stability and will not cause changes in calibration tolerances even at 121 ℃ (high temperature and high pressure). (To protect the circular scale markings, the cleaning temperature should be below 60 ℃.)

10. High thermal stability, able to withstand temperatures ranging from -200 ℃ to+260 ℃ (as a constant volume vessel, we advise customers not to use it directly as a heating vessel)

11、PFAThe material has superhydrophobicity, a smooth surface, and does not produce cross contamination, which affects the sample data

12、Due to the current lack of domesticPFA/FEPFor the level identification standards of plastic volumetric flasks, we temporarily refer to the calibration standards of glass volumetric flasks, as follows:

Single label volumetric flask
