Filters and Column Frits are made with certified quality materials for uniform pore size distribution and maximum column efficiency.
The most important characteristic of a frit, besides the diameter and the thickness, is the porosity. When considering porosity, it is not only the average size of the pore that is of interest, but also the size distribution and the amount of pores available. The size distribution should be a function with narrow tolerances. , we continuously monitor our manufacturing process and maintain strict control of the powders used in our process in order to provide the tightest pore distribution possible. In addition to pore distribution, it is important to consider the pore density, or number of pores available. Although the porosity may be within specification, it is unlikely that this frit would provide adequate flow. Careful control of our powders and process allows Filters to offer the best pore size distribution while maximizing flow properties.

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.
Syringe-driven filter units are available in 0.22, 0.45 and 0.8 micron pore sizes with pvc housings. Membranes available include mf-millipore (mixed cellulose esters), nylon, durapore (pvdf) or polytetrafluoroethylene (ptfe). The 13 mm units are recommended for filtering volumes from 1 to 10 ml. The 25 mm units are recommended for filtering volumes from 10 to 100 ml. 100/pk
Supplier: Oligo & gene synthesis column, RPC column, spe cartridge (oem/ odm), nucleic acid extraction & purification column, protein purification column, high-precision filters/ frits (pe/ptfe/pp) and
Hawach Scientific Co., Ltd filter cartridges divided into big/small pleated filter cartridge, membrane pleated filter cartridges, metal filter cartridge, micro fiber pleated filter cartridge and others. Our filter cartridges are widely used in foods before a filter cartridge is produced, it goes through a series of cleaning processes and filter integrity tests and finally drying 24 hours before packing out. Our filter cartridges are widely used in foods, pharmaceuticals, chemicals, and electronics.
The shell of the filter capsules are made of high-temperature polypropylene material, and the filter cartridges inside are made of hot-melt welding with folded filter cartridges. The product does not contain adhesives and other chemicals. For filter capsules, different filter membrane and different pore size can be selected and autoclaved. It is suitable for filtering 1-20l low-dose liquids, gases, or industrially valuable small-volume liquids.
Hawach filter bags are produced by heat-sealing or car sewing using porous short fiber non-woven fabrics or nylon woven mesh. Filter bags has a deep filtration structure and good integrity. Filter bags have the advantages of large filtration flow, low resistance, long service life, low cost and easy operation.
The filter housings can be quickly filtered and have high filtration accuracy and easy cleaning. Filter housings have the advantages of less adsorption, no media shedding, no dead angle, no leakage, corrosion resistance, and acid and alkali resistance. The filter housing is ideal filtration equipment for food, pharmaceutical, chemical, electronics and other fields.
Filter Membranes we have two types: round disc membrane filters and roll type membrane filter, both of them can be used for filtration and sterilization of liquids, gas, and other samples. Filter Membranes remove all micro-organisms and particles reliably, without any effects on the ingredients during the whole process. We are available in a broad range of pore size and materials such as PTFE, PVDF, Nylon, MCE, CA, PES, GF, PP and etc. OEM service and customized size are also available.
