1. Product introduction The PFA cleaning tank is an upgraded model after the PTFE cleaning bucket. It is specially designed for semiconductor photovoltaic and other industries. It is formed in one piece, so there is no need to worry about leakage. Mainly used for soaking and cleaning flower baskets or wafer cassettes with chip silicon cells. Due to the characteristics of PFA, it can withstand the corrosiveness of cleaning solutions. At the same time, it has a low blank value of metal elements, no dissolution or precipitation, and will not contaminate chip wafers. Other names: anti-corrosion tank, pickling tank, overflow tank, pure water tank, soaking tank, water tank, drip tank Tank capacity: 15L External dimensions: 300*210*240mm Lid: 340*240*45mm Tank capacity: 18L External dimensions: 390*280*205mm Lid: 400*300*42mm Semiconductor wafer cleaning tank size can be customized as required. It also comes with the same PFA lid to prevent contamination. 2. Features: 1. The appearance is translucent, making it easy to observe the reagents in the tank; 2. High and low temperature resistance: -200～+260℃ 3. Corrosion resistance: resistant to strong acid, strong alkali, aqua regia, HF and various organic solvents; 4. Insulation resistance: dielectric properties have nothing to do with temperature and frequency; 5. Anti-pollution: The background value is low, and the content of lead and uranium of metal elements is less than 0.01ppb; 6. No dissolution or precipitation, and will not pollute chips, wafers, silicon wafers, etc.; 8. Stable chemical properties, good recoverability, and not easy to deform; 9.

PFA acid 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. web: https://www.njbinglab.com

Can meet the low detection limit requirements of ICP-OES and ICP-MS and provide laboratory-grade ultrapure acid for demanding analysis applications. The main body of the equipment is made of high-purity PTFE and PFA, and the container in contact with the acid reagent is made of imported PFA material. , lower background, no corrosion, no pollution, can handle HNO3, HCL, HF and other commonly used acids in laboratories. Experiments have shown that after a single distillation of an acid with a metal impurity content of about 10PPB, the metal impurity content can be reduced to about 0.01PPB. If the acid requirements are higher, the purification times can be increased. It is often used to extract high-purity acid in Ultra clean laboratories, trace analysis laboratories, geochemistry, marine systems, geology and minerals, geological brigade, polysilicon, materials and other industries. #Geochemistry #ICPMS #acidpreparation #acidpurification #traceanalysis
