Laboratory HPLC Syringe Filter Wholesale Price

With PES syringe filter membrane mechanically strong character, it can handle high-temperature liquids, with great flow rate (better than PTFE), and low protein binding. With these features, PES syringe filters offer superior performance for use with biological samples and media culture. Workable pH range ~3-14.
Nylon: Nylon membrane filters are hydrophilic, flexible, tear-resistant, and autoclavable. They are resistant to a range of organic solvents and suitable for use with high pH samples. Nylon binds proteins. Unsuitable for acidic solutions. pH range ~3-14.
MCE (Mixed Cellulose Ester) syringe filters are an ideal choice when biological samples are involved. Mixed Cellulose is a hydrophilic membrane offering both low protein binding coefficients and exceptional flow rates.

Syringe filter is a disposable filter unit designed to remove impurities from liquids or gases using a syringe as the fluid delivery system.
It consists of a plastic housing with an inlet and an outlet, and a filter membrane positioned between them.
The filter membrane is often made of materials such as polypropylene, polytetrafluoroethylene (PTFE), or nylon.
To use a syringe filter, the liquid or gas to be filtered is drawn into a syringe, and then the syringe is attached to the inlet of the syringe filter.

Feature and benefits: 0.2 ¦Ìm hydrophobic air filters are excellent industrial air filter media. Testable by water break through (WBT) test or bubble point testing.Passes USP Class VI biosafety tests for plastics. Manufactured in clean room facilities. Range of filtration areas from 4¨C2000 cm2 to support filtration volumes as small as one liter and as large as a large tank vessel

PTFE Syringe Filter is resistant to almost all corrosive chemicals, which makes PTFE syringe filters an ideal choice. However, the disadvantage of natural hydrophobic PTFE is that after many chemicals are diluted with water, the aqueous solution cannot pass through. Need to be wetted with water in advance.

The PTFE syringe filter is tritium-free and has a two-way membrane support and Luer lock inlet/outlet and a safe and suitable syringe. The membrane type and pore size are printed on each filter for easy identification. All Aijiren syringe filters are 100% integrity tested and comply with ISO 9002 standards. The sterilizing filter is sterilized with gamma rays. And detect no pyrogen, no cytotoxicity.

Polypropylene is compatible with acetone, ethyl acetate, methanol, isobutyl alcohol, methanol, and methyl ethyl ketone. Polypropylene is incompatible with cyclohexane, ethers, dichlorobenzene, pentanes, methylene chloride, and trichlorobenzene. Gas, disinfectants or autoclave are recommended to sterilize products made of polypropylene. Maximum temperature use is 135¡ãC.

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.

A syringe filter (or wheel filter) is a single-use, membrane-based device used for the removal of particulate impurities from small (≤ 100 mL) liquid samples. Selected based upon the desired end application, disposable syringe filters are commonly used in labs for fast and efficient filtering, material purification, or even sterilization.

This nylon membrane can be used for alkaline blotting and fixation, but if fixing methods such as baking and ultraviolet rays are used, higher nucleic acid detection sensitivity can be obtained. Since the nylon membrane is a hydrophilic membrane, it does not need to be immersed in ethanol, methanol and other solutions for activation. This product is only for scientific research by professionals, and must not be used for clinical diagnosis or treatment, or used for food or medicine, and must not be stored in ordinary residences. For your safety and health, please wear lab coats and disposable gloves for operation.

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.

Polyethersulfone (PES): Hydrophilic, stable in low pH, have low levels of extractables, and exhibit low protein binding, making them suitable for many aqueous and organic solvents. PES membranes allow higher liquid flow than PTFE. Temperature resistant. pH range ~3-14 (sometimes quoted as 1-14).

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.

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.

The PTFE syringe filter is a general-purpose filter, and it is also Aijiren’s higher-selling syringe filter. PTFE is inert to many aggressive solvents and strong acids and alkalis. These syringe filters can also be exposed to high temperatures and are an excellent choice for HPLC sample preparation. Aijiren offers PTFE syringe filters in a hydrophobic state.

PTFE syringe filters are made of Polytetrafluoroethylene (PTFE) membrane and a polypropylene overmold housing.

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.

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.

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.

PTFE is hydrophobic and needs to be pre-wetted before being used with aqueous solvents. Used for: corrosive solvents, strong acids, alcohols, alkalis, aromatic hydrocarbons. Not suitable for: water-based samples.

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†.

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.

Compared with Nitrocellulose membrane (NC membrane), PVDF membrane has many advantages. PVDF membrane has high mechanical strength, is not easy to break or curl; it has the advantages of low background, wide solvent compatibility, and excellent coloring ability; in addition, PVDF membrane can be repeatedly tested after proper treatment.

PES syringe filter membrane has the characteristics of high mechanical strength, it can handle high temperature liquid, and has a large flow rate (better than PTFE), and low protein binding force. With these functions, PES syringe filters can provide excellent performance for biological samples and culture media. The usable pH range is about 3-14.
