Polypropylene Syringe Filter for Biotechnology

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.

Aijiren syringe filter membrane is made of polyethersulfone (PES), hydrophilic (Hydrophilic), pore size is 0.22¿˜m, shell diameter is 13mm, effective membrane diameter is 11.7mm, and effective membrane area is 1.09cmº†.

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.

Nylon has excellent flow characteristics, extremely low extractable level and mechanical stability, and can provide the best combination of physical parameters to meet the most stringent analysis requirements of 13mm, 25mm and 33mm diameters. Nylon’s natural hydrophilicity, high protein binding capacity and high dirt adsorption capacity are natural advantages.

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.

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.

In order to filter the particles correctly, you need to find the right size filter. You should choose the diameter of the filter carefully. They usually have sizes of 13mm, 25mm and 30mm. Each of these has a different ability to hold particles. According to the sample size, you can choose the appropriate filter diameter. For example, a diameter of 13 mm can be used for 1-10 ml samples. Similarly, 25 mm PVDF syringe filters can be used for sample volumes of 10-100 ml. Their retention is less than 100 ml.

Aijiren’s 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.

MCE features: relatively uniform pore size, high porosity, no media shedding, thin texture, low resistance, fast filtration rate, and minimal adsorption.
The main purpose of MCE: to filter out the particles and bacteria of liquid medicine, gas, oil, beverages, sprinkles, electronic instruments, etc., and can also be used for the detection of particles and bacteria.

Adding a syringe filtration step before the sample injection not only helps to ensure more consistent and reliable results. It also helps protect delicate instruments and extend column life.

In HPLC analysis, the particle size of the chromatographic column packing is small and easily blocked by contaminant particles. t. In HPLC analysis and IC analysis, syringe filters can be used to filter sample solutions, which is an important step in sample pretreatment.

Another way to determine the micron size of columns, 0.45 um for >3 um, and 0.22 um for <3um. 0.45 um membranes are typically used for general filtration and particle removal while 0.2/0.22um membranes, or sterilizing-grade membranes, are most commonly used for solution sterilization (bacteria removal).

Aijiren disposable MCE syringe filter units are designed to provide clear filtration of aqueous and organic solutions from small volumes up to 100 mL.
MCE syringe filters are made from mixed cellulose ester (MCE) membrane and polypropylene overmolded housing.

Its related products are widely used in chemical, pharmaceutical, environmental protection, electronics, food, energy and other fields

Syringe filter is a disposable device used in laboratory settings to filter small volumes of liquid samples. It is commonly utilized to remove particulate matter and microorganisms from solutions before analysis or to protect sensitive instruments from contamination.
Syringe filters consist of a plastic housing with a membrane filter at one end and a female luer lock or luer slip connection at the other end. The filter membrane is typically made of materials such as nylon, polyethersulfone (PES), polytetrafluoroethylene (PTFE), or cellulose acetate.
