Red Sterile Filter

Compressed sterile air filters can be used to create clean rooms free of bacteria and other harmful particles for people with compromised immune systems. Each air supply pump is also equipped with a sterile air filter to ensure the delivery of pollution-free air. These air filters are usually sterilized by gamma rays and packaged separately.

Aijiren’s PVDF syringe filter has hydrophilicity and good chemical compatibility. They can bring precision to your research and ensure the highest level of performance. Our filter series are designed with female Leur-lock inlet and male Leur-slip outlet. In addition, these filters have better mechanical resistance and can withstand high temperatures.

In HPLC analysis, the particle size of the chromatographic column packing is small and easily blocked by contaminant particles. Therefore, samples and solvents must be pre-filtered to remove particulate contaminants and protect the instrument.

The MCE membrane filter provides researchers with the lowest combined filter. Due to their extremely low binding characteristics, these filters provide higher throughput than competing products and reduce filter replacement when filtering protein solutions.

 In HPLC analysis and IC analysis, syringe filters can be used to filter sample solutions, which is an important step in sample pretreatment.

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.

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.

PES syringe filter is mainly used for filtering and sterilizing liquid samples of small volume samples such as a small amount of buffers, protein solutions, additives, various reagents or drugs, and removing particles. It is also the first choice for sterilization and filtration of small samples of HPLC and GC. method.

When using vents, these syringe filters can prevent moisture from passing through. Usable pH range: 1-14. PTFE can be applied to: filtering organic solvents with strong chemical corrosiveness, filtering strong acid solvents, filtering alkali solvents, compatible with gaseous samples, and can handle high-temperature liquids.

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.

Components of PTFE Syringe Filters These syringe filters usually have hydrophobic PTFE filter media and are placed in glass fiber reinforced polypropylene. In order to obtain a higher filtering effect, there are two types of outlets, one is a male Luer sliding outlet, and the other is a female Luer lock inlet.

Designed to be compatible for the use on all common automated filtration systems, Standard syringe filters are color coded. Aijiren syringe filters are labeled for method validation and certification. All syringe filters are autoclavable (121 ¡ãC and 1.1 bar for 30 min).

Use a disposable filter and a disposable sterile syringe to filter and sterilize, first suck the solution to be filtered into the syringe, and then pressure the solution into the sterile container under the filter (which contains a filter membrane with a pore size of 0.22 microns) ,This is done. If the amount of solution to be filtered is large, you can purchase a filter device with a pump.

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.

Polyvinylidene difluoride (PVDF):?designed for high tensile strength, high solvent resistance, and low protein binding, making them suitable for biomedical filtration, sterilization filtration, and HPLC sample preparation. pH range ~1-14.

Aijiren’s Syringe Filter is usually 100pcs/pack. Generally speaking, it is packaged in a plastic box. If the Syringe Filter is packaged in a plastic box, the Syringe Filters will not squeeze each other. The recommended minimum order quantity is 30 boxes.

PTFE: is perfect for the filtration of gaseous or organic solvent-based samples and highly corrosive substances. Hydrophobic so provides chemical resistance to aggressive media and excellent temperature stability allowing an extended sampling range. If used with aqueous samples, the membrane usually requires pre-wetting (normally by using a small amount of alcohol). Can also be used to prevent moisture passing through air vents. pH range ~1-14.

Mainly used in the following aspects: HPLC sample preparation; conventional QC analysis; content uniformity; removal of protein precipitates; dissolution test; food analysis; biofuel analysis; environmental samples

Filter sterilization, that is, removing microorganisms by physical means such as screening or filter material adsorption, is a commonly used method of sterilization. The filtration method is widely used, and some materials that need to be sterilized cannot be heated, such as many vitamin solutions. In addition to being used in the production of beverages and drugs, the air is often sterilized by filtration. When we usually do microbiology experiments, the sterilized container is usually plugged with cotton at the outlet, which is actually filtering to remove microorganisms in the air, so that there is no microbial contamination in the air entering the container.

PTFE Syringe Filters consist of a polytetrafluoroethylene (PTFE) membrane and a polypropylene overmolded housing. Available in 13 mm and 25 mm diameters and 0.22 μm and 0.45 μm pore sizes. PTFE is the membrane of choice for use with aggressive solvents, liquids, and gases that can attack other membranes.

Aijiren’s syringe filters with nylon membranes are compatible with a wide range of solvents, making them ideal for fast filtration of most aqueous and organic solutions. Therefore, when a mixture of sample aqueous solution and organic solvent passes through nylon membrane, fine droplets of extractor solvent accumulate and are separated from the sample aqueous solution. Using this simple method, the total extraction time is only 3-4 minutes; It is environmentally friendly, has no centrifugal effect, provides a higher sample purification rate by filtering receptor phases, and filtering reagents ensures reduced impurities and protects the color column.

Our syringe filters are high quality, packaged and sold at fair competitive prices. They are available in most of the major membrane materials including nylon, PTFE, PES, MCE, PVDF, CA, PP, and GF, and are available in 13mm, 17mm, 25mm and 30mm formats for virgin polypropylene housings.

They are also very useful in the protection of vacuum pump pipelines and have the qualities of high absorption and retention capacity. Due to their advantages, these syringes can be used in laboratory situations as well as industrial applications.
