We can also design and manufacture different standard upon customer's request. How does grinder work? Basically, all our grinders share the same principle, the impact produced by high-speed rotary cut and crush the material, to realize the result of grinding. However, there some differences between different types. For example, the outstanding features of WFJ superfine pulverizer reflect in its cyclone separating technology, the first separating step occurs in the grinding chamber, adjustable cyclone separating device controls different powder of different particle size into a different place, coarser ones stay in the grinding chamber, while finer ones go into next cyclone separating device. The second step happens at the top of the pulse cyclone discharge part. the finest powder which is known as dust is sucked into the dust collecting system, and others are discharged.

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. web: https://www.njbinglab.com Phone/Whatsapp/ Wechat :+8615805176994 Mail: rossnjbzh@gmail.com / rossg@njbinglab.com

PFA conical triangular flasks are generally used in titration experiments.
