0.22 PES Syringe Filter

Syringe filter is a small, disposable device that is commonly used in laboratory settings to filter or clarify fluids. It is designed to be attached to the end of a syringe and acts as a barrier that removes particles and contaminants from the fluid as it is forced through the filter.
Syringe filters typically consist of a plastic housing with a membrane filter inside. The housing has a female luer lock or luer slip connection that allows it to be securely attached to the syringe. The membrane filter, which is the key component, is made of a porous material that allows the fluid to pass through while retaining particles and contaminants above a certain size.

Aijiren disposable cellulose acetate(CA) syringe filter devices are designed to provide clear filterate of aqueous and organic solutionsfrom small volumes up to 100 mL.

Features of MCE: uniform pore size, thin texture, low flow resistance, high filtration speed, low absorption, all items are quality tests for filter efficacy and housing integrity. The housing is pressure tested and can withstand pressures up to 75 psig (5.0 bar). Some filters are individually packaged aseptic packaging, certified, RNase, DNase and DNA free, and non-pyrogenic.

Aijiren’s membrane materials are supplied by the best names in the industry and the ISO9000 certified manufacturing is carried out to the highest standards, in certified clean room conditions, using the latest manufacturing technology to ensure a high quality, consistent product. All the syringe filters are HPLC certified.

Aijiren Syringe Filter is a comprehensive range of non-sterile disposable syringe filters for reliable sample pre-treatment. Reproducible membrane quality and automated manufacturing processes ensure particles are removed from all samples, extending the life of analytical columns and minimizing injection port and valve damage. The Aijiren syringe filter is available in 0.22um and 0.45um porosity, 4, 13, 25 and 30mm diameters.

The syringe filters are designed for easy and efficient filtration of liquids and gases. They feature a syringe-like structure with an inlet and outlet, allowing for direct attachment to a syringe or other fluid delivery systems. The filters remove particulates, microorganisms, and unwanted substances, ensuring clean and clarified samples for analysis.

Sterile syringe filters are syringe-operated filters for the clarification of aqueous solutions (column eluate, tissue culture additives, HPLC samples, etc

Cellulose acetate is a very low protein binding membrane that is ideal for aqueous based samples and biological samples. It is a lower protein binder than either polyethersulphone or PVDF membranes, but has a lower chemical resistance than regenerated cellulose (RC). CA is a strong membrane mechanically and hydrophilic.

PTFE (polytetrafluoroethylene) performance: suitable for water system and various organic solvents, resistant to all solvents, low solubility. It has the characteristics of air permeability and water impermeability, large air flux, high particle retention rate, good temperature resistance, resistance to strong acids, alkalis, organic solvents and oxidants, resistance to aging, non-stickiness, non-flammability, non-toxicity, and biocompatibility. Its related products are widely used in chemical, pharmaceutical, environmental protection, electronics, food, energy and other fields

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.

PES syringe filter is hydrophilic in nature, and has low protein binding, high flow rate and excellent chemical stability. In addition, it also contributes to oxidation stability, high heat and low concentration of extractable elements.

In chromatographic experiments, the sample is placed on the chromatographic column for analysis after the sampler is injected. However, the inner core of the sampler and the chromatographic column is relatively thin. If there are large particles in the sample, it may cause the device to block , Need to use Syringe Filter for preliminary sample filtration treatment.

Our Syringe Filters are high quality, well packaged and sold at a fair competitive price. They are available in most of the major membrane materials including Nylon, PTFE, PES, MCE, PVDF, CA, PP, and GF which are supplied in 13mm, 17mm, 25mm and 30mm formats in virgin polypropylene housings.

The special color contrast provided on the surface of the MCE film helps to detect particles and minimize eye strain. It is ideal for the recovery and retention of bacteria in colony counting and sterility testing, as well as water/wastewater analysis and other microbiological tests.

The shell of PTFE Syringe Filter is made of polypropylene (PP) with excellent chemical stability. It is made of different colors, which is convenient for users to distinguish products of different materials and avoid confusion. The filter membrane adopts imported high-performance filter membrane with stable product quality and good reproducibility. It is an ideal choice for laboratory filtration of samples. The standard interface is convenient to connect to various syringes, and it can also be directly connected to the needle of the 7725 valve, and the sample can be injected directly after filtration.

Characteristics of PVDF Syringe Filters:

Low protein binding
Good chemical compatibility and low extractable
Superior mechanical resistance
Higher resistance to temperature

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.

Uniform aperture,Thin texture,Low flow resistance,High filtration speed,Little absorption,All items are quality tests for filter efficacy and housing integrity. The housing is pressure tested for use with up 75 psig (5.0 bar) of pressure.

Aijiren’s PVDF syringe filters are hydrophilic in nature and have strong chemical compatibility. They can bring precision to your research and ensure the highest level of performance. Our filter range is designed with female leur-Lock imports and male Leur-slip exports. In addition, these filters have better mechanical resistance and it can withstand high temperatures.

Due to the high hydrophobicity of the PVDF membrane, it needs to be soaked in an appropriate solution such as ethanol before use to achieve the purpose of activation and make the membrane easier to bind proteins. This product is compatible with many dyes, such as Ponceau-S red, Coomassie brilliantblue, Sypro ruby, Transillumination, Toluidine blue, CPTS, Colloidal gold, India inkAmido black. Among them, after dyeing with dyes such as Ponceau and CPTS, the dyes can be washed off and the film can be used for further analysis; while dyes such as Coomassie Brilliant Blue, India ink, and amide black are irreversible, the film cannot be used after dyeing. For further analysis.

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.

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.

Polypropylene is compatible with acetone, ethyl acetate, methanol, isobutanol, methanol and methyl ethyl ketone. Polypropylene is incompatible with cyclohexane, ether, dichlorobenzene, pentane, methylene chloride and trichlorobenzene. It is recommended to use gas, disinfectant or autoclave to sterilize products made of polypropylene. The maximum operating temperature is 135¡ãC.
