Sterile Syringe Filters for HPLC

PTFE is a hydrophobic membrane that is chemically resistant to almost all solvents. It can be used with corrosive media, such as strong acids, alcohols, alkalis, and aromatics. The unit is readily available, allowing simple, fast and reliable HPLC or GC analysis of ultra-clean small-volume samples. PTFE filters can also be used to prevent moisture from passing through the vents.

Sterile filtration is used in many applications: serum-containing or non-serum-containing media that supports the growth of cell cultures, reagents or solutions containing sensitive components that will degrade during high temperature processing, and when there is no autoclave, filtration should be added to the sterile growth media supplement Liquid, filter samples to avoid microbial growth during storage, filter buffers, remove particulate matter and avoid microbial growth during storage, filter biological samples to be analyzed, avoid microbial contamination of expensive equipment, filter environmental samples to be analyzed, filter fermentation liquids, Further purification or analysis.

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.

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.

Our 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, 25mm formats in virgin polypropylene housings.

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

Due to the high hydrophobicity of the PVDF membrane, it needs to be immersed in ethanol, methanol or other suitable solutions for activation. This product is only for scientific research by professionals, and must not be used for clinical diagnosis or treatment, or used for food or medicine, and must not be stored in ordinary residences. For your safety and health, please wear lab coats and disposable gloves for operation.

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.

PES syringe filter has the characteristics of hydrophilicity, low protein binding, high flow rate and good chemical stability. In addition, it also contributes to oxidation stability, high heat and low concentration of extractable elements. Aijiren’s PES syringe filters are ideal for ion chromatography, tissue culture filtration, protein, nucleic acid and high temperature liquid filtration. It helps you get accurate results in sensitive analysis of ionic analytes.

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.

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.

A syringe filter is a quick, convenient and reliable filter tool used routinely in the laboratory. Because they don’t need to change the membrane and filter cleaning, it’s eliminating the complex and time-consuming preparation.  

13mm, 25mm 0.22um, 0.45um hydrophobic PVDF (polyvinylidene fluoride) membrane syringe filter is a filtration device commonly used in laboratory settings to remove particulates and microorganisms from fluids.
It’s important to note that specific details of hydrophobic PVDF membrane syringe filters, such as pore size, diameter, and filtration capacity, can vary between manufacturers and product lines.
Therefore, it’s recommended to consult the product specifications or contact the supplier for precise information about the syringe filters you are considering for your specific application.

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.

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.

MCE features: relatively uniform pore size, high porosity, no media shedding, thin texture, low resistance, fast filtration rate, and minimal adsorption.
The main purpose of MCE: to filter out the particles and bacteria of liquid medicine, gas, oil, beverages, sprinkles, electronic instruments, etc., and can also be used for the detection of particles and bacteria.

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.

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

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).

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.

Customers can use sterile syringe filters to filter out particles and contamination in the fluid. Filtration requires a 0.2¦Ìm pore size to produce a sterile filtrate. The volume of the solution to be filtered varies from a few milliliters to several liters. Typical fluids may include serum-containing media, buffers, biological or protein samples, reagents, or other fluids, and need to be free of particulates or microbial contamination.

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.
In addition, chromatography commonly used in environmental analysis requires that no inorganic contaminants be introduced during sample pretreatment.
