Syringe Filter produced by Aijiren is often used for sample preparation before chromatographic analysis experiment preparation. Syringe Filter is used to filter impurities in reagents, protect chromatographic columns in HPLC autosampler or other sophisticated analytical instruments, and prevent these precision instruments from being impurity. Affect the blocking of the fine analysis pipeline inside.

Aijiren syringe filters with luer lock connection are a series of non-sterile disposable syringe filters for reliable sample preparation. The reproducible membrane quality and automated manufacturing process ensure that particles are removed from each sample, prolong the life of the analytical column and minimize damage to the inlet or valve.

The syringe filter is a fast, convenient and reliable filter tool commonly used in laboratories. Since there is no need to replace the filter membrane and filter cleaning, complicated and time-consuming preparations are eliminated. It is widely used in sample pre-filtration, particle removal, aseptic filtration of liquids and gases. It is the preferred method for filtering small samples before loading into HPLC and GC, and is usually used with disposable syringes.

A syringe filter with a hydrophobic PTFE membrane can be used to filter strong solvents, acids and alkalis. Not suitable for filtering aqueous liquids. Filters with hydrophilic polytetrafluoroethylene can be used to filter strong solvents, acids and alkalis. However, these syringe filters can also be used to filter aqueous liquids, which makes this type of use very versatile.

PTFE disposable syringe filter is a fast, convenient and reliable filter tool, often used in laboratories. It has the characteristics of beautiful appearance, light weight and high cleanliness. Because there is no need to replace the filter membrane and clean the filter, it saves tedious and time-consuming preparation work. It is widely used in laboratories, widely used for sample pre-filtration, clarification and removal of particulate matter, and sterilization and filtration of liquids and gases.

PVDF membrane has many advantages. PVDF film has high mechanical strength, is not easy to break or curl; it has the advantages of low background, wide solvent compatibility, and excellent coloring ability; in addition, PVDF film can be tested repeatedly after proper treatment. It has strong filtering ability and can get repeated experimental results.

The mixed cellulose ester (MCE) membrane filter is made of cellulose acetate and nitrocellulose, an appropriate amount of acetone, n-butanol, ethanol, etc. Since the MCE membrane is bio-embedded, it is one of the most widely used membranes in analysis and research applications. Hydrophilicity, non-toxicity and hygiene are its biggest advantages. It is a porous membrane filter material with relatively uniform pore size distribution. Absolute pore size and porosity as high as 80‰. It is mainly used for the filtration of water-based solutions, so it is also called water-based membrane. This product is flammable. It should be sealed, moisture-proof and fire-proof during storage.

The Syringe Filter produced by Aijiren uses different types of filter membranes, and different materials can be applied to different reagents and different experiments. PES Syringe Filter is a popular product because of the hydrophilicity of PES, which ensures the adaptability and stability of Syringe Filter. . The diameter of the PES Syringe Filter in the picture is 33mm, the large diameter is easy to operate, and the PES material guarantees the production quality.

The filtration sterilization method generally uses a filter membrane. First, use a depth filter to remove large particle deposits. Then use a filter membrane for filtration. The pore size of the filter membrane is generally 0.2 μm or 0.45 μm, which can filter out most of the nutrient cells of microorganisms. The sterile syringe filter has PP, PTFE or nylon membrane. The pore size of the filter membrane is 0.2um or 0.45μm, and the pore size of the filter membrane is usually selected according to the packing size of the analytical column. Aijiren provides filter membranes with two pore sizes and different materials.

Aijiren’s syringe filter is very reliable. It is a sterile polyethersulfone (PES) syringe filter. Each batch of syringe filter membranes has passed the HPLC extractable test certification. Filter size: 13mm Membrane diameter and pore size: 0.45μm, 100 per pack. Pore structure suitable for laboratory sterilization of small-volume samples. The filter surface area increases the flow rate and throughput, and it also makes it easier to filter the solution because it reduces the pressure required to empty the syringe.

Aijiren’s nylon membrane has two types of pore sizes: 0.45μm and 0.22μm. Since the nylon membrane is a hydrophilic membrane, it does not need to be immersed in a solution such as ethanol or methanol for activation. This product is for professional use only for scientific research, not for clinical diagnosis or treatment, not for food or medicine, and not for storage in ordinary residences. For your safety and health, please wear lab coats and disposable gloves during operation.

There are many specifications of PP syringe filter. The diameters of 13mm and 25mm can be used for different sizes and types of syringe needles. The diameter of the filter membrane is 0.22 and 0.45, which can filter impurities of different diameters. Aijiren produces PP syringe filters. The reason is to make it easier for customers to prepare samples. Samples filtered out of impurities will not affect the autosampler injection, and can protect the chromatographic column and prevent impurities from entering the chromatographic column.

The PVDF Syringe Filter produced by Aijiren is very suitable for sample filtration in chemical experiment analysis. The sample is filtered before reagent analysis, which can protect the chromatographic column in Autosampler and ensure the accuracy of the test results. PVDF Syringe The method of using Filter is very convenient, and it can be used directly without pre-processing, which speeds up the speed of sample preparation.

The Syringe Filter produced by Aijiren has a hydrophilic membrane made of PES. PES not only has extremely low protein binding and high flow characteristics, but also has passed ion chromatography certification. Polyethersulfone is more heat-resistant than most membranes and can be used up to 100°C. PES filter membrane can be used for: strong bases, alcohols, proteins, peptides. Do not use with: acids, ketones, esters, halogenated hydrocarbons or aromatic hydrocarbons.

The PTFE membrane equipped with Syringe Filter by Aijiren has extensive chemical compatibility and extremely low solubility, and is currently the most chemically resistant membrane among all filter membranes. Aijiren’s innovative design enables the PTFE filter to achieve a perfect balance between increasing the effective filtration area and reducing the sample retention volume. Usually the packaging is 100 pcs/pack, in bags or drums.
