Wholesale Cellulose Acetate Syringe Filter

The nylon membrane of the syringe filter should be compatible with the chemical characteristics of the sample. The nylon membrane should be compatible with various water-based and organic solvents. The membrane should also have high resistance to HPLC solvents and chemicals. The 0.45mm aperture ensures that you have enough capacity and throughput to process samples efficiently and quickly.

13mm, 25mm 0.22um, 0.45um hydrophobic PVDF (polyvinylidene fluoride) membrane syringe filter is a filtration device commonly used in laboratory settings to remove particulates and microorganisms from fluids.
It’s important to note that specific details of hydrophobic PVDF membrane syringe filters, such as pore size, diameter, and filtration capacity, can vary between manufacturers and product lines.
Therefore, it’s recommended to consult the product specifications or contact the supplier for precise information about the syringe filters you are considering for your specific application.

PTFE Syringe Filter is resistant to almost all corrosive chemicals, which makes PTFE syringe filters an ideal choice. However, the disadvantage of natural hydrophobic PTFE is that after many chemicals are diluted with water, the aqueous solution cannot pass through. Need to be wetted with water in advance.

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.

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.

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.

The nylon membrane used in the syringe filter has high mechanical strength, chemical stability, can be tolerated by most organic solvents, has very low extractables, has good thermal stability and natural hydrophilicity, and is filtered by most aqueous solutions characteristic.

Aijiren’s PVDF syringe filters are hydrophilic in nature and have strong chemical compatibility. They can bring precision to your research and ensure the highest level of performance. Our filter range is designed with female leur-Lock imports and male Leur-slip exports. In addition, these filters have better mechanical resistance and it can withstand high temperatures.

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.

Aijiren disposable syringe filter devices are designed to provide fast and efficient filtration of aqueous and organic solutionsfrom small volumes up to 100 mL.

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.

Our Syringe Filters are high quality, well packaged and sold at a fair competitive price. They are available in most of the major membrane materials including Nylon, PTFE, PES, MCE, PVDF, CA, PP, and GF which are supplied in 13mm, 17mm, 25mm and 30mm formats in virgin polypropylene housings.

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.

Aijiren’s membrane materials are supplied by the best names in the industry and the ISO9000 certified manufacturing is carried out to the highest standards, in certified clean room conditions, using the latest manufacturing technology to ensure a high quality, consistent product. All the syringe filters are HPLC certified.

In the sample application of choosing the appropriate syringe filter and syringe, draw your sample into the syringe and place the filter on the syringe. If you are using a leur lock filter, make sure you have properly secured the filter into the syringe tip .Push a few drops through the filter with the syringe filter facing up and “top”. Place the filter in the overturned collection container and push the sample through the syringe filter by applying gentle positive pressure. The syringe filter to be cleared and the maximum To maximize sample throughput, remove the filter from the syringe and draw air into the syringe. Then reinstall the filter and push the plunger to force some air through the filter.

Due to the high hydrophobicity of the PVDF membrane, it needs to be immersed in ethanol, methanol or other suitable 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.

UHPLC Precolumn Filter
• Economical protection against microparticles.
• Extend UHPLC column lifetime.
• Negligible effect on column performance.
• Universal fit—easily connects directly to any brand column.
• Leak tight to 15,000 psi (1,034 bar).
• Does not contribute to system backpressure.
• Does not contribute to band broadening.

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).

Aijiren’s Syringe Filter is usually 100pcs/pack. Generally speaking, it is packaged in a plastic box. If the Syringe Filter is packaged in a plastic box, the Syringe Filters will not squeeze each other. The recommended minimum order quantity is 30 boxes.

Polypropylene (PP) is recommended for one time use only with low vapor transmission. Polypropylene is a rigid plastic that is translucent. At room temperature, polypropylene exhibits excellent chemical resistance to acids, alcohols, and bases. 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.

PTFE is a hydrophobic membrane that is chemically resistant to almost all solvents. It can be used with corrosive media, such as strong acids, alcohols, alkalis, and aromatics. The unit is readily available, allowing simple, fast and reliable HPLC or GC analysis of ultra-clean small-volume samples. PTFE filters can also be used to prevent moisture from passing through the vents.

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.

Among the many medium types of Syringe Filters produced by Aijiren, Polypropylene Syringe Filter is a special one. Because Polypropylene is often used to make the shell of Syringe Filter, there are fewer types of membranes made of Polypropylene. Aijiren finally decided to use this material to produce Syringe Filter after studying the production materials of many different manufacturers and the usage of different customers.
