The Sterile syringe filter produced by Aijiren is a single-use membrane-based filtration facility that is mostly used to remove particulate impurities from liquid and gas samples before analysis by HPLC, ion chromatography, gas chromatography, ICP, and dissolution testing methods. . Correctly filtering samples in chromatographic experiments can improve the quality and consistency of analysis results and reduce instrument downtime. The sterile syringe filter adopts high-temperature aseptic processing and vacuum packaging of liquid to ensure the cleanliness of the syringe filter. It is recommended to be used once.

In order to filter the particles correctly, you need to find the right size filter. You should choose the diameter of the filter carefully. They usually have sizes of 13mm, 25mm and 30mm. Each of these has a different ability to hold particles. According to the sample size, you can choose the appropriate filter diameter. For example, a diameter of 13 mm can be used for 1-10 ml samples. Similarly, 25 mm PVDF syringe filters can be used for sample volumes of 10-100 ml. Their retention is less than 100 ml.

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.

Hydrophobic PTFE (Polytetrafluoroethylene) syringe filters are suitable for gaseous and organic solutions, with excellent performance for high corrosive samples. It is possible for an extended sampling range using hydrophobic PTFE filters for wider chemical resistance to aggressive substances and outstanding temperature stability. A PTFE syringe filter is an ideal choice for filtering and de-gassing chromatography solvents.

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.

They are also very useful in the protection of vacuum pump pipelines and have the qualities of high absorption and retention capacity. Due to their advantages, these syringes can be used in laboratory situations as well as industrial applications.

The Non-sterile Disposable Syringe Filter is a versatile filtration device used in laboratories for sample preparation and clarification. It consists of a polypropylene housing with a membrane filter, providing efficient filtration of particulate matter and microorganisms.

The Syringe Filter produced by Aijiren can be equipped with many different types of filter membranes, which can be selected according to the reagents that customers need to filter.

Our syringe filters are made from high-purity polytetrafluoroethylene (PTFE) membrane for superior performance and durability. PTFE is an ideal material for HPLC applications with excellent chemical compatibility, low protein binding, and minimal analyte adsorption. This ensures sample integrity for accurate, reproducible results.

Low protein binding rate: These filters have a low protein binding rate. When the sample is less bound, its fluidity increases, and it also has better diffusion properties. Samples purified with PES filters can produce better results by tolerating slight changes in their density-related properties.

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.

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

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.

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.

Syringe filter is a disposable device used in laboratory settings to filter small volumes of liquid samples. It is commonly utilized to remove particulate matter and microorganisms from solutions before analysis or to protect sensitive instruments from contamination.
Syringe filters consist of a plastic housing with a membrane filter at one end and a female luer lock or luer slip connection at the other end. The filter membrane is typically made of materials such as nylon, polyethersulfone (PES), polytetrafluoroethylene (PTFE), or cellulose acetate.

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 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.

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.

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 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.

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.
