0.22 PTFE Syringe Filter

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.

A syringe filter is a disposable filtration device that is attached to a syringe for the purpose of filtering or clarifying liquid samples.
It consists of a plastic housing with a membrane filter that allows for the removal of particles or contaminants from the sample as it passes through the filter.
Syringe filters are widely used in research laboratories, quality control laboratories, pharmaceutical industries, biotechnology companies, and other applications where the filtration of liquid samples is necessary.

Polyethersulfone filter has the characteristics of high flow rate, low extraction loss, and higher mechanical resistance than cellulose membrane. It is suitable for biological, pharmaceutical, sterilization and filtration. The membrane is sealed in the polymer shell without using any adhesive. Each unit is ETO or gamma ray sterilized and guaranteed to be pyrogene-free.

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†.

The syringe filters are designed for easy and efficient filtration of liquids and gases. They feature a syringe-like structure with an inlet and outlet, allowing for direct attachment to a syringe or other fluid delivery systems. The filters remove particulates, microorganisms, and unwanted substances, ensuring clean and clarified samples for analysis.

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 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.

Aijiren’s membrane materials are supplied by the best names in the industry and the ISO9000 certified manufacturing is carried out to the highest standards, in certified clean room conditions, using the latest manufacturing technology to ensure a high quality, consistent product. All the syringe filters are HPLC certified.

The reinforcement ring can provide greater strength to the shell to prevent leakage and bursting (30mm product pressure is rated at 120 psi). The shell is made of solvent-resistant, low-extraction polypropylene resin, specifically selected for wide compatibility with common HPLC sample matrices. The solution can be filtered at temperatures up to 100¡ãC, which is convenient and easy to use.

In chromatographic experiments, the sample is placed on the chromatographic column for analysis after the sampler is injected. However, the inner core of the sampler and the chromatographic column is relatively thin. If there are large particles in the sample, it may cause the device to block , Need to use Syringe Filter for preliminary sample filtration treatment.

The EPA VOA vials feature a secure closure mechanism to maintain sample integrity and prevent sample leakage or contamination. The vials typically come with a screw cap equipped with a septum, ensuring a tight and leak-proof seal. This closure mechanism ensures the preservation of volatile organic compounds during storage and transportation.

1. The pore size of the needle-punched membrane is accurate, providing comprehensive protection for your instrument and chromatographic column
2. There is a clear label on the Nylon syringe filter to avoid confusion
3. The luer interface of the needle filter with lock can prevent the filter from flying out due to excessive pressure

Aijiren’s PVDF syringe filters are hydrophilic in nature and have strong chemical compatibility. They can bring precision to your research and ensure the highest level of performance. Our filter range is designed with female leur-Lock imports and male Leur-slip exports. In addition, these filters have better mechanical resistance and it can withstand high temperatures.

Use Aijiren CA syringe filter to remove interfering substances and fine particles to the rated pore size, thereby obtaining a cleaner sample extract. Cellulose acetate (CA) syringe filters are ideal for filtering tissue culture media and filtering sensitive biological samples. Adding a syringe filtration step before chromatographic injection not only helps to ensure more consistent and reliable results, it also helps protect the instrument and extend the life of the column. Economical choice Syringe filters are available in a variety of sizes and membrane types to meet the needs of any application.

13 mm Syringe Filters: For sample volumes <10 mL range; Ideal choice for most applications; Holdup (dead) volume is <15 ul; Female inlet luer lock; Maximum operation pressure <15 bar; Bubble point: Hydrophilic 2-3 bar; Hydrophobic 1-1.2 bar.

 In HPLC analysis and IC analysis, syringe filters can be used to filter sample solutions, which is an important step in sample pretreatment.

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 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 sterile syringe filter provided by Aijiren has a cellulose acetate or PES filter membrane. A sterile membrane with a pore size of 0.2um is an ideal material for sterilization and filtration, while a pore size of 0.45¦Ìm can be used for clarification. The sterile needle filter is sterilized by gamma radiation, which avoids the toxic residue caused by other sterilization methods

The membrane materials produced by Aijiren are provided by the most famous people in the industry, and in the ISO9000 certified production process, under certified clean room conditions, the latest manufacturing technology is used to ensure high-quality and stable products to achieve the highest standards . All syringe filters are HPLC certified.
