PVDF Streil Syringe Filter

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.

The syringe filter has the following characteristics:
1. Convenient, readily available, easy to operate, economical and practical.
2. Reliable bacteria retention efficiency ensures the filtering and sterilization effect.
3. Larger effective membrane filtration area: 1.09cm2.
4. High flow rate, high throughput, dead volume no more than 10¦Ìl.
5. Very low protein adsorption.
6. Pass HPLC dissolution test.

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.

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.

By using Aijiren syringe filters unwanted particles are removed which can otherwise cause contamination and clogging of sensitive instrumentation. So, filtering your samples leads to an increase of lifetime and less downtime of chromatographic columns and equipment, gives more consistent and reproducible results and thereby saves time and money.

Polypropylene (PP) is recommended for one time use only with low vapor transmission. Polypropylene is a rigid plastic that is translucent. At room temperature, polypropylene exhibits excellent chemical resistance to acids, alcohols, and bases. 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.

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.

Characteristics of PVDF Syringe Filters:
Hydrophilic
Low protein binding
Good chemical compatibility and low extractable
Superior mechanical resistance
Higher resistance to temperature

PTFE Syringe Filters are universal filters that are inert to a wide variety of aggressive solvents and strong acids and bases. These syringe filters can also be exposed to high temperatures and are an excellent choice for HPLC sample preparation. We offer PTFE syringe filters in both their hydrophobic and hydrophilic states.

PVDF syringe filters are made of hydrophilic PVDF membrane and a polypropylene overmold housing. Available in 13 mm and 25 mm diameters and 0.22 μm and 0.45 μm pore sizes.

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.

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.

Disposable non-sterile syringe filter devices are designed to provide fast and efficient filtration, premium quality and economy. The membrane could be PTEF, PVDF, PES, Nylon, MES, PP, CA, and can be suitable for different situations.

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 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.

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.

Cellulose Acetate Syringe Filter Surfactant-free membrane for cleanliness in downstream applications, Filter type printed on the filter for ease of identification, Convenient, larger pack sizes,Gamma sterilised.

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.

Instructions for use and precautions:
1. It must be used with disposable syringes and glass syringes. The interface is standard. Put the needle filter on the syringe first, then pour the liquid into the syringe, press the push rod down, and collect the filtered liquid.
2. Do not use a syringe smaller than 10cc, because the small-volume column may cause the pressure to exceed the upper limit and cause damage to the filter membrane.
3. Only for laboratory use, one-time use, non-renewable.
4. The filtrate at the beginning of the part should be discarded. The volume is about the dead volume of the filter. Taking 25mm as an example, discard the first 1mL filtrate; or pre-clean the filter with 1 to 2mL of solution.

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.

Aijiren’s CA Syringe Filter 90% is exported to the world’s major economically developed countries. Filters can provide foundry services according to customer needs. The produced filters have good consistency between batches, and there are strict control procedures from raw materials to production processes to in and out of warehouse delivery management to ensure the quality and use value of the products.

Aijiren Tech Aijiren Syringe Filters are a comprehensive range of non-sterile disposable syringe filters for reliable sample preparation. Reproducible membrane quality and automated manufacturing processes ensure particulates are removed from each and every sample, extending analytical column lifetime and minimising injection port or valve damage.

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.

These syringe filters feature a user-friendly design, allowing for convenient and hassle-free filtration. They are compatible with standard luer lock syringes, enabling simple attachment and detachment. The filters come pre-sterilized and individually packaged, ensuring convenience and minimizing the risk of contamination.
