NJbinglab Resuable PFA Volumetric Flasks,Class A, With Screw Cap, For Polishing Fluid

Product details

Advantages of PFA volumetric flasks: 1. Excellent chemical stability and corrosion resistance: These volumetric flasks are made of high-purity imported experimental grade PFA material, which has excellent resistance to various chemical reagents, including strong acids, bases, aqua regia and various organic solvents. This ensures the integrity of the volumetric flask and prevents sample contamination. 2. High temperature resistance: PFA volumetric flasks are able to withstand temperatures from -200 Celsius degree to +260 Celsius degree and are suitable for various high temperature experiments and industrial applications. However, it is recommended not to use it directly as a heating container to protect the calibration mark. 3. Excellent transparency and easy observation: The volumetric flask has a highly transparent body, which allows a clear view of the internal liquid. This helps to accurately monitor the progress of the experiment and helps to accurately measure the volume. 4. Precision calibration and accuracy: Each flask is calibrated with laser etched marks and verified using a precision electronic balance to ensure Class A accuracy, in accordance with DIN EN ISO 1042 standards. This ensures reliable and repeatable results in various experiments. 5. Smooth surface and easy to clean: The smooth inner and outer surfaces of the flask prevent sample adhesion and make cleaning a breeze. This facilitates reuse and ensures hygiene between experiments. 6. Tight seal and leak-proof design: The flask is equipped with a screw cap and thread seal to prevent sample contamination and leakage, ensuring the integrity of the storage solution. 7. Low background and low leaching: PFA material has low background and leaching properties, making it an ideal choice for trace analysis experiments such as ICP-MS and ICP-OES, where even tiny impurities can affect the results.
