Aijiren brand syringe filters are HPLC certified to ensure reliable and consistent results. Water, methanol, and acetonitrile are used for testing, and HPLC is used for detection at 210 and 254 nm wavelengths. None absorbs ultraviolet light, which can provide a purer analytical background.

As an important tool for filtering reagents, the Nylon syringe filter plays a very important role, especially in chromatographic consumables. A slightly larger impurity particle in the reagent may cause clogging of the instrument.

Product applications: water purification, HPLC sample preparation, mobile phase solution filtration, cell culture, microbial filtration or sampling, protein precipitate removal, particle removal and monitoring, QC analysis, content consistency, dissolution testing, environmental sampling, food analysis. Generally speaking, 0.45 ¦Ìm pore size is suitable for removing particles from samples or the mobile phase solution of chromatography equipment, and 0.22 ¦Ìm is suitable for filtering microorganisms.

Hydrophilic nylon membranes have extremely low levels of extractables and contain no wetting agents. They offer good chemical resistance and are ideal for aqueous and most organic samples. Filters are Triton-free and have a bidirectional membrane support and luer lock inlet/outlet for a secure fit to the syringe. Membrane type and pore size are printed on each filter for easy identification. All Cole-Parmer syringe filters are 100% integrity tested and manufactured in accordance with ISO 9002 standards. Sterile filters are sterilized by gamma radiation. They are certified nonpyrogenic, noncytotoxic, and are blister packed.

Syringe filter is a small, disposable device used for filtration purposes in laboratories and other scientific settings. It consists of a plastic housing with a membrane filter at one end and a female luer lock or male luer slip connection at the other end, allowing it to be attached to a syringe.
The purpose of a syringe filter is to remove impurities, particulates, or unwanted substances from a liquid sample before it is injected or analyzed. The membrane filter within the syringe filter acts as a barrier, selectively allowing only certain particles or molecules to pass through while retaining larger particles.

Customers can use sterile syringe filters to filter out particles and contamination in the fluid. Filtration requires a 0.2¦Ìm pore size to produce a sterile filtrate. The volume of the solution to be filtered varies from a few milliliters to several liters. Typical fluids may include serum-containing media, buffers, biological or protein samples, reagents, or other fluids, and need to be free of particulates or microbial contamination.

You can choose a PTFE needle-punched filter to improve the filtration efficiency in any area. They provide high-performance filtration through an application-centric design and can be used in various industries that process organic samples.

Sterile filtration is used in many applications: serum-containing or non-serum-containing media that supports the growth of cell cultures, reagents or solutions containing sensitive components that will degrade during high temperature processing, and when there is no autoclave, filtration should be added to the sterile growth media supplement Liquid, filter samples to avoid microbial growth during storage, filter buffers, remove particulate matter and avoid microbial growth during storage, filter biological samples to be analyzed, avoid microbial contamination of expensive equipment, filter environmental samples to be analyzed, filter fermentation liquids, Further purification or analysis.

Convenient and Easy to Use£ºPES Syringe filters can be sterilized by autoclave at 125¡ãC for 15 minutes£¬Enhanced Luer Lock inlet prevents leakage; outlet fitting is a standard size male Luer-slip fitting for ease of filtrate collection, Come in bulk packs of 100 and not individually wrapped

In the sample application of choosing the appropriate syringe filter and syringe, draw your sample into the syringe and place the filter on the syringe. If you are using a leur lock filter, make sure you have properly secured the filter into the syringe tip .Push a few drops through the filter with the syringe filter facing up and “top”. Place the filter in the overturned collection container and push the sample through the syringe filter by applying gentle positive pressure. The syringe filter to be cleared and the maximum To maximize sample throughput, remove the filter from the syringe and draw air into the syringe. Then reinstall the filter and push the plunger to force some air through the filter.

The PTFE Syringe Filter in the picture has an aperture of 0.22, an outer diameter of 25mm, and a purple color. Aijiren also offers many other colors of Syringe Filter, such as yellow, pink, blue, green, etc. Customers can choose according to their preferences . The Syringe Filter produced by Aijiren can be equipped with many different types of filter membranes, which can be selected according to the reagents that customers need to filter.

The nylon membrane used in the syringe filter has high mechanical strength, chemical stability, can be tolerated by most organic solvents, has very low extractables, has good thermal stability and natural hydrophilicity, and is filtered by most aqueous solutions characteristic.
