PFA acid purifier
1. Product introduction:
Acid purifier: also known as acid purification system, high-purity acid purifier, acid reagent purifier, high-purity acid distillation purifier, etc. In laboratory work, the purity of the acid is often poor, causing deviations and errors in the analysis results. Commercially available pure acids are often expensive and difficult to meet the large demand for acids in daily analyses. Therefore, purifying and optimizing the quality of acid is an economically feasible way. Our acid purifier can be used in laboratories to purify HNO3, HCl, HF, alkali solutions and organic solvents. After purification, the purity of the acid is further improved. Later in the experiment, our unit's Teflon series reagent bottles can be used to collect high-purity acid.
2. Working principle:
The acid purifier uses the principle of thermal radiation to keep the liquid temperature below the boiling point to evaporate, and then condenses the acid vapor to prepare high-purity water and high-purity reagents. It is widely used in sample processing and analysis experiments.
3. Product features:
1. It can meet the low detection limit requirements of ICP and ICP-MS and provide laboratory-grade ultrapure acid for demanding analysis applications. All containers used are made of Teflon corrosion-resistant non-adsorption plastic and can handle laboratories such as HNO3, HCl, HF, etc. Commonly used acids.
2. Experiments have proven that after a single distillation of an acid with a metal impurity content of about 10 ppb, the metal impurity content can be reduced to about 0.01 ppb. If the acid requirements are higher, the purification times can be increased.

Pipettes are indispensable tools in laboratories, research facilities, and medical settings, used to accurately measure and transfer liquids. To ensure consistent and reliable results, it's crucial to properly maintain and care for your pipettes. In this article, we'll provide essential tips for pipette maintenance to help prolong their lifespan and maintain accuracy.
1. Regular Cleaning
Clean your pipettes regularly to prevent cross-contamination between samples. Use a mild detergent and distilled water to clean the external surfaces. For the internal components, use a lint-free cloth dampened with isopropanol or ethanol to wipe down the pipette shaft and piston. Make sure to follow the manufacturer's guidelines for cleaning to avoid damaging delicate components.
2. Calibrations and Verification
Schedule regular calibrations and verifications of your pipettes to ensure accurate measurements. Calibration checks should be performed by trained professionals using calibrated equipment. Verification using gravimetric or photometric methods can help confirm the accuracy of your pipettes when dispensing specific volumes.
3. Proper Handling
Handle pipettes with care to avoid mechanical damage. Always use the appropriate force when operating the plunger to prevent excessive wear on internal components. Avoid dropping pipettes or subjecting them to impact, as this can lead to misalignment and inaccurate measurements.
4. Tip Selection and Replacement
Choose pipette tips that are compatible with your specific pipette model. Use high-quality, certified tips to ensure accurate and consistent results. Replace tips between each sample to prevent cross-contamination. Make sure the tips are securely attached to the pipette to prevent leakage or imprecise measurements.
5. Storage and Handling
Store your pipettes in a clean and dry environment to prevent dust and contaminants from affecting their performance. Use pipette stands to keep them upright and avoid contact with surfaces. If your pipettes are not in use for an extended period, store them with the plunger released to relieve stress on internal components.
Conclusion
Proper maintenance of pipettes is essential for obtaining accurate and consistent results in laboratory and medical settings. By following these tips and adhering to manufacturer guidelines, you can ensure that your pipettes remain in optimal condition, extend their lifespan, and contribute to the reliability of your research and analyses.
