Properties of PFA: 1. Translucent appearance, smooth inner wall, no water hanging on, easy to clean; 2. Temperature resistance: operating temperature -200~+260â??; 3. Insulation resistance: dielectric properties have nothing to do with temperature and frequency; 4. Anti-pollution: low metal element value; The PFA condensation filter column is an important device used in gas reactions. Its main function is to purify the reaction gas and remove impurities in it. The role of the PFA condensation filter column in gas reactions will be introduced in detail below. 1. Condensation of reaction gases In many gas reactions, the gas produced by the reaction often needs to be condensed before it can be purified and utilized. The PFA condensation filter column uses external cooling to cool the reaction gas and condense it. During this process, the PFA material has excellent chemical stability and high temperature tolerance, and can withstand gas reaction conditions of high temperature and high pressure. 2. Filter impurities in the reaction gas During the reaction process, some impurities are often produced in the gas, which will affect the success or failure of the reaction. Sometimes toxic or harmful substances will remain in the reacted gas, which needs to be filtered and purified. The filter elements in the PFA condensation filter column can effectively remove impurities in the reaction gas and improve the gas purity, thus ensuring the accuracy, effectiveness and repeatability of the reaction. 3. Protect downstream equipment Before the reaction, we need to process the reaction gas through a PFA condensation filter column to ensure that the reactants are not contaminated in subsequent equipment. At the same time, the filter column can also effectively prevent impurities in the reaction gas from causing corrosion or damage to downstream equipment, so the use of condensation filter columns is also a protection mechanism for downstream equipment. In short, the PFA condensation filter column plays a very important role in gas reactions, and can play multiple roles such as condensation, purification, and protection of downstream equipment. In practical applications, it is necessary to fully consider the gas reaction conditions and the performance of the filter column, and select a suitable condensation filter column to complete the reaction.

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 â?? to+260 â??, 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.
Our Kale will be packed in the field but this does not mean food safety is less strict; We put special attention on this kind of crops packed outside. Every leaf we pack will be well trimmed no more than three fourths of an inch from the outer leaves. We can pack it Also in the packing shed if the client requires it. Quality Our kale consist of only one type of variety which is well trimmed, ot stuned, free from decay, and damage caused by yellow or discolored leaves, seeds items, wilting, bud burn, freezing, dirt, diseases, insects or mechanical or other means. Temperature Kale should be stored at 0 ° C (32 ° F) with 98 to 100% RH. Storage at -1 ° C (31.1 ° F) may cause freezing, while storage at 1 ° C (33.8 ° F) may promote senescence-related storage losses, especially if held in long-term storage. High RH minimizes decay; light in the storage reduces physiological disorders, mainly leaf yellowing, and weight loss.
