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.
Due to the high hydrophobicity of the PVDF membrane, it needs to be soaked in an appropriate solution such as ethanol before use to achieve the purpose of activation and make the membrane easier to bind proteins. This product is compatible with many dyes, such as Ponceau-S red, Coomassie brilliantblue, Sypro ruby, Transillumination, Toluidine blue, CPTS, Colloidal gold, India inkAmido black. Among them, after dyeing with dyes such as Ponceau and CPTS, the dyes can be washed off and the film can be used for further analysis; while dyes such as Coomassie Brilliant Blue, India ink, and amide black are irreversible, the film cannot be used after dyeing. For further analysis.

Another way to determine the micron size of columns, 0.45 um for >3 um, and 0.22 um for <3um. 0.45 um membranes are typically used for general filtration and particle removal while 0.2/0.22um membranes, or sterilizing-grade membranes, are most commonly used for solution sterilization (bacteria removal).
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.
Aijiren’s sterile syringe filter has a bidirectional diaphragm support and Luer lock inlet/outlet, which can be securely mounted on the syringe. The type and pore size of the membrane are printed on each filter for easy identification. All Aijiren syringe filters are 100% integrity tested and manufactured according to ISO 9002 standards. The sterile filter is sterilized by gamma radiation. They are proven to be pyrogen-free, non-cytotoxic, and are blister packs.

Membrane materials are supplied under the industry’s best names, and ISO9000 certified manufacturing uses the latest manufacturing technology to ensure high quality and consistent products, performed to the highest standards in certified cleanroom conditions. All syringe filters are HPLC certified.
Selected PES syringe filters provide a cleaner sample extract by removing interfering materials and fine particles down to the rated pore size. Performing a syringe filtration step before chromatographic injection helps ensure more consistent and reliable results, and helps protect delicate instruments and extend column life.
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.
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).
The special color contrast provided on the surface of the MCE film helps to detect particles and minimize eye strain. It is ideal for the recovery and retention of bacteria in colony counting and sterility testing, as well as water/wastewater analysis and other microbiological tests.
Features of MCE: uniform pore size, thin texture, low flow resistance, high filtration speed, low absorption, all items are quality tests for filter efficacy and housing integrity. The housing is pressure tested and can withstand pressures up to 75 psig (5.0 bar). Some filters are individually packaged aseptic packaging, certified, RNase, DNase and DNA free, and non-pyrogenic.
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.
Polypropylene is compatible with acetone, ethyl acetate, methanol, isobutanol, methanol and methyl ethyl ketone. Polypropylene is incompatible with cyclohexane, ether, dichlorobenzene, pentane, methylene chloride and trichlorobenzene. It is recommended to use gas, disinfectant or autoclave to sterilize products made of polypropylene. The maximum operating temperature is 135¡ãC.
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 advantages of Syringe Filter: The low extractable membrane and shell ensure that no filter contaminants are added to your samples. Aijiren performs performance tests under actual HPLC conditions. The integrated 1mm borosilicate glass prefilter (30mm device) ensures higher confidence in samples with high solids content.
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.
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.
The Syring Filter with nylon membrane produced by Aijiren has good hydrophilicity, acid and alkali resistance, and oxidation resistance.
