China Supply 20-60mL EPA VOA Vials

Syringe filter is a small, disposable device used for filtration purposes in laboratories and other scientific settings. It consists of a plastic housing with a membrane filter at one end and a female luer lock or male luer slip connection at the other end, allowing it to be attached to a syringe.
The purpose of a syringe filter is to remove impurities, particulates, or unwanted substances from a liquid sample before it is injected or analyzed. The membrane filter within the syringe filter acts as a barrier, selectively allowing only certain particles or molecules to pass through while retaining larger particles.

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.

Aijiren Syringe Filters is 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.

Aijiren’s syringe filters with nylon membranes are compatible with a wide range of solvents, making them ideal for fast filtration of most aqueous and organic solutions. Therefore, when a mixture of sample aqueous solution and organic solvent passes through nylon membrane, fine droplets of extractor solvent accumulate and are separated from the sample aqueous solution. Using this simple method, the total extraction time is only 3-4 minutes; It is environmentally friendly, has no centrifugal effect, provides a higher sample purification rate by filtering receptor phases, and filtering reagents ensures reduced impurities and protects the color column.

The Nylon Syringe Filter produced by Aijiren is mostly used for reagent filtration or sample preparation. Nylon Syringe Filter has different specifications. The filter membrane diameter is 13mm, 25mm and 33mm, which can be selected according to the capacity of the sample. Aijiren provides 0.22μm and 0.45. Two μm specifications are convenient for customers to choose. The Nylon Syringe Filter produced by Aijiren meets customers’ requirements and needs for product preparation.

MCE Syringe Filter is generally used to filter neutral or partial neutral aqueous solutions, and can be used as experimental sample clarification filtration, liquid chromatography injection filtration and so on. Not suitable for filtering organic solvents and strong acid and alkali solutions. This filter is for one-time use, filtering about 10 ml at a time (specifically, there is a big difference according to the impurities of the filtered liquid), and the filter membrane cannot be disassembled. 0.45¦Ìm can remove conventional impurities and some bacteria visible to the naked eye. Generally used in conjunction with the syringe.

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.

Aijiren’s PVDF membrane (imported packaging, 6.6¡Á8.5cm, 0.2¦Ìm) is a pre-cut polyvinylidene fluoride (PVDF) imprinting membrane with a size of 6.6¡Á8.5cm and a pore size of 0.2¦Ìm. It is most commonly used for the transfer of protein from gel to membrane in immunoblot (Western blot), and can also be used for adsorption analysis, amino acid analysis, N-terminal protein sequencing, dot and slot blot detection, Glycoprotein color development and lipopolysaccharide analysis, etc.

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

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.

Hydrophilic nylon membranes have extremely low levels of extractables and contain no wetting agents. They offer good chemical resistance and are ideal for aqueous and most organic samples. Filters are Triton-free and have a bidirectional membrane support and luer lock inlet/outlet for a secure fit to the syringe. Membrane type and pore size are printed on each filter for easy identification. All Cole-Parmer syringe filters are 100% integrity tested and manufactured in accordance with ISO 9002 standards. Sterile filters are sterilized by gamma radiation. They are certified nonpyrogenic, noncytotoxic, and are blister packed.

This nylon membrane can be used for alkaline blotting and fixation, but if fixing methods such as baking and ultraviolet rays are used, higher nucleic acid detection sensitivity can be obtained. Since the nylon membrane is a hydrophilic membrane, it does not need to be immersed in ethanol, methanol and other 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 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.

Features of the syringe filter: Luer lock inlet provides a sealed syringe connection, with various filter types, porosities and diameters. Color coding is easy to identify. Rugged polypropylene shell. Can be autoclaved to 121℃ for 15 minutes. The quantity exceeds the minimum order quantity to save more.

Aijiren’s CA Syringe Filter 90% is exported to the world’s major economically developed countries. Filters can provide foundry services according to customer needs. The produced filters have good consistency between batches, and there are strict control procedures from raw materials to production processes to in and out of warehouse delivery management to ensure the quality and use value of the products.

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 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.

PES syringe filter is hydrophilic in nature, and has low protein binding, high flow rate and excellent chemical stability. In addition, it also contributes to oxidation stability, high heat and low concentration of extractable elements.

The Aijiren Tech Syringe Filter is a comprehensive non-sterile disposable syringe filter for reliable sample preparation. Reproducible membrane quality and automated manufacturing processes ensure particles are removed from all samples, extending the life of analytical columns and minimizing injection port and valve damage.
