Non-sterile Disposable HPLC Syringe Filter for Manufacturer

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.

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.

PP housing membrane syringe filter refers to a syringe filter wif a housing made of polypropylene (PP).

Polypropylene is a commonly used material for syringe filter housings due to its chemical compatibility, low extractables, and resistance to a wide range of solvents. PP housings provide structural support to teh filter membrane and help maintain its integrity during filtration.
These syringe filters find applications in various fields such as pharmaceuticals, biotechnology, environmental analysis, food and beverage testing, and research laboratories where precise filtration is required to ensure sample purity and integrity.

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.

PTFE (polytetrafluoroethylene) performance: suitable for water system and various organic solvents, resistant to all solvents, low solubility. It has the characteristics of air permeability and water impermeability, large air flux, high particle retention rate, good temperature resistance, resistance to strong acids, alkalis, organic solvents and oxidants, resistance to aging, non-stickiness, non-flammability, non-toxicity, and biocompatibility. Its related products are widely used in chemical, pharmaceutical, environmental protection, electronics, food, energy and other fields

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 PTFE syringe filter is a general-purpose filter, and it is also Aijiren’s higher-selling syringe filter. PTFE is inert to many aggressive solvents and strong acids and alkalis. These syringe filters can also be exposed to high temperatures and are an excellent choice for HPLC sample preparation. Aijiren offers PTFE syringe filters in a hydrophobic state.

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

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.

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. It is widely used in the sample pre filtration, removal of particles, aseptic filtration of liquids and gases. It is the preferred method to filter small samples before loading into HPLC and GC ,and it is often used with disposable syringe.

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†.

Uniform aperture,Thin texture,Low flow resistance,High filtration speed,Little absorption,All items are quality tests for filter efficacy and housing integrity. The housing is pressure tested for use with up 75 psig (5.0 bar) of pressure.

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.

Disposable syringe filters are widely used in labs for quick and efficient filtering, material purification or even sterilization for solutions <250mL, to avoid setting ups of Buchner filters or similar.

Disposable 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 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.

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.

Aijiren’s PVDF syringe filter has hydrophilicity and good chemical compatibility. They can bring precision to your research and ensure the highest level of performance. Our filter series are designed with female Leur-lock inlet and male Leur-slip outlet. In addition, these filters have better mechanical resistance and can withstand high temperatures.

Syringe Filters with hydrophobic PTFE membranes can be used for filtration of strong solvents, acids and alkalis. Not suitable for filtration of aqueous liquids. Filters with hydrophilic PTFE can be used for filtration of strong solvents, acids and alkalis. However, these syringe filters can also be used for the filtration of aqueous liquids, which makes this type very versatile.

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.

Aijiren brand syringe filters are HPLC certified to ensure reliable and consistent results. Water, methanol, and acetonitrile are used for testing, and HPLC is used for detection at 210 and 254 nm wavelengths. None absorbs ultraviolet light, which can provide a purer analytical background.
