Green 33mm PTFE Syringe Filter

Polyethersulfone filter has the characteristics of high flow rate, low extraction loss, and higher mechanical resistance than cellulose membrane. It is suitable for biological, pharmaceutical, sterilization and filtration. The membrane is sealed in the polymer shell without using any adhesive. Each unit is ETO or gamma ray sterilized and guaranteed to be pyrogene-free.

Aijiren disposable MCE syringe filter units are designed to provide clear filtration of aqueous and organic solutions from small volumes up to 100 mL.
MCE syringe filters are made from mixed cellulose ester (MCE) membrane and polypropylene overmolded housing.

PES (Polyethersulfone ) syringe filter is natural hydrophilic which makes is an ideal choice (highly recommended) for aqueous solutions and alcohols. It’s not necessary to treat the filter membrane surface with wetting agents.

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.

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.

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.

In order to filter the particles correctly, you need to find the right size filter. You should choose the diameter of the filter carefully. They usually have sizes of 13mm, 25mm and 30mm. Each of these has a different ability to hold particles. According to the sample size, you can choose the appropriate filter diameter. For example, a diameter of 13 mm can be used for 1-10 ml samples. Similarly, 25 mm PVDF syringe filters can be used for sample volumes of 10-100 ml. Their retention is less than 100 ml.

With PES syringe filter membrane mechanically strong character, it can handle high-temperature liquids, with great flow rate (better than PTFE), and low protein binding. With these features, PES syringe filters offer superior performance for use with biological samples and media culture. Workable pH range ~3-14.
Nylon: Nylon membrane filters are hydrophilic, flexible, tear-resistant, and autoclavable. They are resistant to a range of organic solvents and suitable for use with high pH samples. Nylon binds proteins. Unsuitable for acidic solutions. pH range ~3-14.
MCE (Mixed Cellulose Ester) syringe filters are an ideal choice when biological samples are involved. Mixed Cellulose is a hydrophilic membrane offering both low protein binding coefficients and exceptional flow rates.

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.

Although Aijiren has attractive prices, the focus is still on quality. The membrane materials are provided by the most famous people in the industry, and in the ISO9000 certified production process, the latest manufacturing technology is used, and the production is carried out under the highest standard under certified clean room conditions to ensure high quality and stable products. . All syringe filters are HPLC certified.

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.

The syringe filter has the following characteristics:
1. Convenient, readily available, easy to operate, economical and practical.
2. Reliable bacteria retention efficiency ensures the filtering and sterilization effect.
3. Larger effective membrane filtration area: 1.09cm2.
4. High flow rate, high throughput, dead volume no more than 10¦Ìl.
5. Very low protein adsorption.
6. Pass HPLC dissolution test.

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.

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.

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.

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

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.

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.
