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.

1. Product introduction: The appearance of the PFA Erlenmeyer flask is in the shape of a flat-bottomed cone, wide at the bottom and narrow at the top. It has a cylindrical neck and an opening wider than the neck at the top, which can be closed with a stopper. PFA Erlenmeyer flask is also called PFA reaction flask, , PFA Olenmayer flask, etc. It is a metal-free fluororesin Erlenmeyer flask with excellent chemical resistance and heat resistance. Suitable for micro analysis, trace analysis, ultra-trace analysis ICP-MS/OES/AAS analysis and other experiments. 2. Technical parameters Product name: PFA Erlenmeyer flask Specifications (ml): 125/250/500ml Material: PFA Withstand temperature: -200~+260℃ 3. Product characteristics A. High temperature resistance: operating temperature reaches 260°C; B. Low temperature resistance: It has good mechanical toughness; even if the temperature drops to -196°C, it can maintain an elongation of 5%; C. Corrosion resistance: It is inert to most chemical solvents, resistant to acids and alkali, water and various organic solvents; D. Aging resistance: has the best aging life among plastics; E. High lubrication: It is a solid material with a low friction coefficient; F. Non-adhesion: It is the smaller surface tension in solid materials; G. There are two options: threaded port and sealing plug. 4. Purpose: It has a large specific gravity and good heat resistance, so it can be heated in a water bath or oil bath. It can be equipped with a shaker oscillator for experiments. 5.

PFA, also known as soluble polytetrafluoroethylene or Teflon, is used for trace analysis, isotope detection, ICP-MS/OES/AAS analysis, and other experiments. The temperature resistance range of PFA bottle washing is very wide, and it can withstand temperatures from -200 ℃ to+260 ℃, which means it can be used under various experimental conditions without being limited by temperature. The PFA bottle washing tube and body are reliably sealed, with sensitive spraying performance, fast recovery, and no residue left. It can be sprayed into various container positions, making cleaning very convenient. Therefore, using PFA bottle washing can make experiments more convenient. In addition, the nozzle and cap of PFA bottle washing are formed in one go, and its structure is very tight, so there will be no leakage. This is crucial for the accuracy of the experiment. PFA bottle washing can also replace volumetric flasks to prepare standard solutions, which can be controlled to add samples and water dropwise. This means that using PFA bottle washing can conduct experiments more accurately and reduce errors. Suitable for industries such as semiconductors, photovoltaics, biopharmaceuticals, and petrochemicals.

Welcome for the inquiry. 1351 Clear glass Desiccator with porcelain plate Product Description It is a non-vacuum desiccator, and therefore has no stopcock. The sturdy glass top fits easily on the thick lip of the desiccator, and features a knob handle for removing or replacing the lid. The lips of both the lid and the desiccator itself are ground glass, and should be greased with petroleum jelly before use. In addition to helping create an air-tight seal, the grease also helps cushion the lid when it is set down in place. To help prevent damage from being set down too forcefully, the lid can be carefully slid on, or off, of the desiccator once greased. Desiccators can be used, though not exclusively, for preserving moisture-sensitive items, protecting hygroscopic or water-reacting chemicals, as well as removing traces of water from samples that need drying. There are 8 sizes available : 120 mm desiccator, 150 mm desiccator, 180 mm desiccator, 210 mm desiccator, 240 mm desiccator, 300 mm desiccator, 350 mm desiccator, 400 mm desiccator.
