0.22 PTFE Red Syringe Filter

As an important tool for filtering reagents, the Nylon syringe filter plays a very important role, especially in chromatographic consumables. A slightly larger impurity particle in the reagent may cause clogging of the instrument.

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.

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.

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.

Cellulose acetate is a very low protein binding membrane that is ideal for aqueous based samples and biological samples. It is a lower protein binder than either polyethersulphone or PVDF membranes, but has a lower chemical resistance than regenerated cellulose (RC). CA is a strong membrane mechanically and hydrophilic.

In HPLC analysis, the particle size of the chromatographic column packing is small and it is easy to be blocked by impurity particles. Therefore, samples and solvents need to be filtered in advance to remove particulate contaminants and protect the instrument. Ion chromatography, which is commonly used in environmental analysis, also requires that no inorganic pollutants be introduced in sample pretreatment.

The Syringe Filters are suitable for a wide range of applications in pharmaceutical, biotechnology, environmental, and research laboratories. From sterilizing and clarifying liquids to removing particulates prior to analysis, these filters are versatile tools that can enhance the quality

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.

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.

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.

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.

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.

Although Aijiren has attractive prices, the focus is still on quality. The membrane materials are provided by the most famous people in the industry, and in the ISO9000 certified production process, the latest manufacturing technology is used, and the production is carried out under the highest standard under certified clean room conditions to ensure high quality and stable products. . All syringe filters are HPLC certified.

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 syringe filters are available in various pore sizes and membrane materials to accommodate different filtration requirements. They are suitable for a wide range of laboratory applications, including sample preparation, clarification, and sterilization. The filters provide reliable performance and consistent filtration results, contributing to accurate and reproducible data in analytical chemistry, microbiology, and other fields.

PTFE: is perfect for the filtration of gaseous or organic solvent-based samples and highly corrosive substances. Hydrophobic so provides chemical resistance to aggressive media and excellent temperature stability allowing an extended sampling range. If used with aqueous samples, the membrane usually requires pre-wetting (normally by using a small amount of alcohol). Can also be used to prevent moisture passing through air vents. pH range ~1-14.

Nylon has excellent flow characteristics, extremely low extractable level and mechanical stability, and can provide the best combination of physical parameters to meet the most stringent analysis requirements of 13mm, 25mm and 33mm diameters. Nylon’s natural hydrophilicity, high protein binding capacity and high dirt adsorption capacity are natural advantages.

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.

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.

When using vents, these syringe filters can prevent moisture from passing through. Usable pH range: 1-14.
