Nylon membrane has high strong mechanical strength, chemical stability, can be tolerated by most organic solvents, extremely low in extractables, good thermal stability (up to 50¡ãC), natural hydrophilic and the majority of water solution filter characteristics. It more often applied to the common organic solvent HPLC mobile phase filtering.

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.

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.

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.

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.

Syringe filters are a fast, convenient and reliable filter tool that is routinely used in laboratories. No need to replace membranes or clean filters, which eliminates the need for complex and time-consuming preparations. Widely used in pre-sample filtration, particle removal, and aseptic filtration of liquids and gases. This method is suitable for rinsing small samples before loading into HPLC and GC, and is often used in disposable syringes.

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.

Hydrophilic PTFE syringe filters offer a choice for aqueous samples that are diluted with harsh chemicals. These filters can handle high-temperature liquids, excellent flow rates, low protein binding, and are compatible with most bases, acids and organic solvents.

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.

The hydrophobic PTFE membrane has extensive chemical compatibility and very low dissolution, and is currently the most chemically resistant membrane among all filter membranes. Aijiren’s innovative design allows the PTFE filter to achieve a perfect balance between the increase in effective filtration area and the decrease in sample retention volume. The filter can withstand higher operating pressures, effectively avoiding leakage.

Aijiren syringe filter is a fast, convenient and reliable filter tool, usually used in the laboratory. Since they do not require membrane replacement and filter cleaning, complicated and time-consuming preparations are eliminated. It is widely used for sample prefiltration, particle removal, aseptic filtration of liquids and gases.

The Nylon Syringe Filter produced by Aijiren is mostly used for reagent filtration or sample preparation. Nylon Syringe Filter has different specifications. The filter membrane diameter is 13mm, 25mm and 33mm, which can be selected according to the capacity of the sample. Aijiren provides 0.22μm and 0.45. Two μm specifications are convenient for customers to choose. The Nylon Syringe Filter produced by Aijiren meets customers’ requirements and needs for product preparation.

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.

Selected PES syringe filters provide a cleaner sample extract by removing interfering materials and fine particles down to the rated pore size. Performing a syringe filtration step before chromatographic injection helps ensure more consistent and reliable results, and helps protect delicate instruments and extend column life.

Syringe filters are made of many different types of materials. Various materials, diameters, pore sizes, and sterile and non-sterile options are on our list. These syringe filters provide excellent microfiltration performance for HPLC, water treatment, environment, biotechnology, beverage, food, pharmaceutical and other related fields.

The nylon membrane of the syringe filter should be compatible with the chemical characteristics of the sample. The nylon membrane should be compatible with various water-based and organic solvents. The membrane should also have high resistance to HPLC solvents and chemicals. The 0.45mm aperture ensures that you have enough capacity and throughput to process samples efficiently and quickly.

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

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).

Among the many medium types of Syringe Filters produced by Aijiren, Polypropylene Syringe Filter is a special one. Because Polypropylene is often used to make the shell of Syringe Filter, there are fewer types of membranes made of Polypropylene. Aijiren finally decided to use this material to produce Syringe Filter after studying the production materials of many different manufacturers and the usage of different customers.

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.

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.

Syringe filter is a small, disposable device used for filtering liquids or gases.It consists of a plastic housing with a membrane filter at one end and a female luer lock or luer slip connection at the other end, which allows it to be attached to a syringe or other fluid delivery system.
Syringe filters are commonly used in laboratory and research settings to remove particles, microorganisms, or other impurities from samples before analysis or further processing. The membrane filter in a syringe filter acts as a barrier, allowing only the desired components of the sample to pass through while retaining any larger particles or contaminants.
The choice of membrane material depends on the nature of the sample and the substances to be filtered.
