Hot sale lab consumable 0.22um/ 0.45um 25mm HPLC Syringe Filter with PP Housing+Membrane Filter

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.

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.

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.

By using Aijiren syringe filters unwanted particles are removed which can otherwise cause contamination and clogging of sensitive instrumentation. So, filtering your samples leads to an increase of lifetime and less downtime of chromatographic columns and equipment, gives more consistent and reproducible results and thereby saves time and money.

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.

Use Aijiren CA syringe filter to remove interfering substances and fine particles to the rated pore size, thereby obtaining a cleaner sample extract. Cellulose acetate (CA) syringe filters are ideal for filtering tissue culture media and filtering sensitive biological samples. Adding a syringe filtration step before chromatographic injection not only helps to ensure more consistent and reliable results, it also helps protect the instrument and extend the life of the column. Economical choice Syringe filters are available in a variety of sizes and membrane types to meet the needs of any application.

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.

Membrane separation technology is hailed as “one of the most promising high-tech developments in the middle of the 21st century”. Among them, microporous membrane separation is the most eye-catching application in the fields of biology, chemical analysis and pharmaceuticals. There is no need to change the membrane and clean the filter, save the complicated and time-consuming preparation work, and is widely used in the laboratory.

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.

PES syringe filter is mainly used for filtering and sterilizing liquid samples of small volume samples such as a small amount of buffers, protein solutions, additives, various reagents or drugs, and removing particles. It is also the first choice for sterilization and filtration of small samples of HPLC and GC. method.

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.

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.

Cellulose acetate is a very low protein binding membrane that is ideal for aqueous based samples and biological samples. It is a lower protein binder than either polyethersulphone or PVDF membranes, but has a lower chemical resistance than regenerated cellulose (RC). CA is a strong membrane mechanically and hydrophilic.

Convenient and Easy to Use£ºPES Syringe filters can be sterilized by autoclave at 125¡ãC for 15 minutes£¬Enhanced Luer Lock inlet prevents leakage; outlet fitting is a standard size male Luer-slip fitting for ease of filtrate collection, Come in bulk packs of 100 and not individually wrapped

The hydrophobic PTFE membrane has extensive chemical compatibility and very low dissolution, and is currently the most chemically resistant membrane among all filter membranes. Aijiren’s innovative design allows the PTFE filter to achieve a perfect balance between the increase in effective filtration area and the decrease in sample retention volume. The filter can withstand higher operating pressures, effectively avoiding leakage.

Aijiren’s syringe filters and vials reduce HPLC sample preparation time and the use of consumables, and the track-etched membrane is also essential for extruding liposomes for encapsulation and targeted drugs.

The advantages of nylon: 1. Toughness 2. Wear resistance 3. Smoothness 4. Light weight 5. Insect resistance 6. Anti-mold and the material is not easy to generate static electricity, deformation, pilling and ageing.

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.

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 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.

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.
