Sterile Syringe Filter for Lab Analysis

Polyethersulfone (PES):?Hydrophilic, stable in low pH, have low levels of extractables, and exhibit low protein binding, making them suitable for many aqueous and organic solvents. PES membranes allow higher liquid flow than PTFE. Temperature resistant. pH range ~3-14 (sometimes quoted as 1-14).

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.

Aijiren Tech Aijiren Syringe Filters are a comprehensive range of non-sterile disposable syringe filters for reliable sample preparation. Reproducible membrane quality and automated manufacturing processes ensure particulates are removed from each and every sample, extending analytical column lifetime and minimising injection port or valve damage.

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.

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.

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.

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

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.

In the sample application of choosing the appropriate syringe filter and syringe, draw your sample into the syringe and place the filter on the syringe. If you are using a leur lock filter, make sure you have properly secured the filter into the syringe tip .Push a few drops through the filter with the syringe filter facing up and “top”. Place the filter in the overturned collection container and push the sample through the syringe filter by applying gentle positive pressure. The syringe filter to be cleared and the maximum To maximize sample throughput, remove the filter from the syringe and draw air into the syringe. Then reinstall the filter and push the plunger to force some air through the filter.

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.

syringe filter is a small, disposable filter device that is commonly used in laboratory settings for the filtration of liquids. It is designed to be attached to a syringe, allowing the liquid to be passed through the filter membrane under pressure.

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.

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.

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.

The MCE membrane filter provides researchers with the lowest combined filter. Due to their extremely low binding characteristics, these filters provide higher throughput than competing products and reduce filter replacement when filtering protein solutions.

Polypropylene is compatible with acetone, ethyl acetate, methanol, isobutyl alcohol, methanol, and methyl ethyl ketone. Polypropylene is incompatible with cyclohexane, ethers, dichlorobenzene, pentanes, methylene chloride, and trichlorobenzene. Gas, disinfectants or autoclave are recommended to sterilize products made of polypropylene. Maximum temperature use is 135¡ãC.

Aijiren manufactures a Syringe Filter that comes in a number of different membranes, PTFE membranes are hydrophilic and inert and fit many different types of agents, the details below contain the chemicals compatible with the PTFE Syringe Filter. In addition, the article number and specific specifications of Aijiren PTFE have been clearly described. If you have any needs, please leave a comment below for inquiry.

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.

Components of PTFE Syringe Filters These syringe filters usually have hydrophobic PTFE filter media and are placed in glass fiber reinforced polypropylene. In order to obtain a higher filtering effect, there are two types of outlets, one is a male Luer sliding outlet, and the other is a female Luer lock inlet.

Syringe filtration is a crucial technique in laboratory settings, playing a vital role in sample preparation for various analytical methods.

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).

Syringe filters are made of many different types of materials. Various materials, diameters, pore sizes, and sterile and non-sterile options are on our list. These syringe filters provide excellent microfiltration performance for HPLC, water treatment, environment, biotechnology, beverage, food, pharmaceutical and other related fields.

The shell of PTFE Syringe Filter is made of polypropylene (PP) with excellent chemical stability. It is made of different colors, which is convenient for users to distinguish products of different materials and avoid confusion. The filter membrane adopts imported high-performance filter membrane with stable product quality and good reproducibility. It is an ideal choice for laboratory filtration of samples. The standard interface is convenient to connect to various syringes, and it can also be directly connected to the needle of the 7725 valve, and the sample can be injected directly after filtration.

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.
