1. Product Guide
PFA transparent tubes are used to transport different liquids and gases, and are resistant to strong acids and alkalis, high and low temperatures. Different British tubes and capillaries can be processed. They are used in industries with high cleanliness requirements such as the petroleum industry, biopharmaceuticals, and the semiconductor industry. PFA tubes are used for liquid and gas transportation during semiconductor manufacturing. In semiconductor processes, many liquid and gas media need to be transported under high temperature conditions while maintaining high purity and chemical inertness. PFA tubes are ideal for transporting chemicals and solvents due to their excellent high temperature resistance and inertness to chemical corrosives, such as acid and alkali solutions, sputtering source materials, photoresists, and deionized water.

Reagent contamination can elevate the background concentration of analytes in a sample, making it essential for laboratories to invest in high-purity acids for trace metal analyses. With limited sample sizes, maintaining low blank levels is crucial for reproducibility. NJbinglabâ??s SCH sub-boiling distillation systems enable laboratories to produce their own high-purity acids at significantly reduced costs.
The chemical reagents utilized during analysis are a major contributor to analytical blanks. Sub-boiling distillation is recognized as the most effective method for acid purification. This technique employs Wrap-around silicone heating jacket to vaporize the surface liquid at a temperature typically 20 �°C below the boiling point.
In conventional distillation, the boiling process generates aerosolized particles, leading to contamination in the distillate. In contrast, the gentle surface evaporation used in sub-boiling distillation minimizes spray or droplet formation, resulting in high-purity acids.
Advantages:
1. Utilizes the same technology as commercial production for ultra-trace metals analysis.
2. Achieves up to 90% cost savings on ultra-pure acids by purifying lower-cost reagent-grade acids.
3. Allows you to purify only the quantity you need, when you need it.
4. Produces up to 90 mL per hour (SCH-III).
PFA purification system:
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.
