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.

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).

The PES film is sealed in the polymer shell without the use of any adhesive. Each unit can provide ETO or Gamma radiation disinfection, and ensure that there is no pyrogen.

The HPLC Syringe Filter provides efficient filtration of samples in high-performance liquid chromatography (HPLC) applications. These filters are designed to remove particulate matter, contaminants, and debris from samples, ensuring clean and reliable results. With precise pore sizes and high flow rates, they enable rapid and efficient filtration without sample loss.

Aijiren’s PVDF membrane (imported packaging, 6.6¡Á8.5cm, 0.2¦Ìm) is a pre-cut polyvinylidene fluoride (PVDF) imprinting membrane with a size of 6.6¡Á8.5cm and a pore size of 0.2¦Ìm. It is most commonly used for the transfer of protein from gel to membrane in immunoblot (Western blot), and can also be used for adsorption analysis, amino acid analysis, N-terminal protein sequencing, dot and slot blot detection, Glycoprotein color development and lipopolysaccharide analysis, etc.

Sterile Syringe Filters
While the primary function of a syringe filter is to remove particulates from a liquid sample, you will select either a sterile or non-sterile filter, depending on the end application.
Sterile syringe filters are used to sterilize non-sterile solutions or clarify sterile solutions. Learn more about sterile filters by application.

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.

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.

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.

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.

PVDF syringe filters have excellent chemical compatibility, mechanical strength and low extractability. In these filters, the maximum allowable housing pressure is 150 psi. It improves the filtering speed. These filters have high temperature resistance due to their materials. They have excellent flow rate and temperature stability.

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).

Although Aijiren has attractive prices, the focus is still on quality. The membrane materials are provided by the most famous people in the industry, and in the ISO9000 certified production process, the latest manufacturing technology is used, and the production is carried out under the highest standard under certified clean room conditions to ensure high quality and stable products. . All syringe filters are HPLC certified.

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.

The MCE membrane offers exceptional retention capabilities, trapping particles and microorganisms as small as 0.22 μm in size. This fine filtration helps safeguard sensitive analytical instruments, HPLC systems, and other lab equipment from contamination, preserving their optimal performance and extending their lifespan.

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.

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.

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.

Sample preparation for high-throughput Ultra High Performance Liquid Chromatography (UHPLC)/High Performance Liquid Chromatography (HPLC) analysis can be time consuming when using multiple consumables such as a syringe, syringe filter, sample vial, cap, and septum. Aijiren HPLC filters result in faster sample preparation than the normal syringe filter method.

Aijiren syringe filter membrane use method introduction: before inhaling the sample, suck about 1ml of air into the syringe, so as to minimize the liquid residue, suck the sample into the syringe, invert the syringe and clear all the residues on the top Clean, connect the needle filter to the syringe, tighten it gently to ensure a good seal, filter the sample in the syringe and inject it into the sample bottle, and then follow the steps to maximize the recovery rate, remove the filter, and suck air into the syringe, Reconnect the filter head and eject all residual samples.

Syringe Filters with hydrophobic PTFE membranes can be used for filtration of strong solvents, acids and alkalis. Not suitable for filtration of aqueous liquids. Filters with hydrophilic PTFE can be used for filtration of strong solvents, acids and alkalis. However, these syringe filters can also be used for the filtration of aqueous liquids, which makes this type very versatile.

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.
