0.22 Red PTFE Syringe Filter

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.

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.

In HPLC analysis, the particle size of the chromatographic column packing is small and it is easy to be blocked by impurity particles. Therefore, samples and solvents need to be filtered in advance to remove particulate contaminants and protect the instrument. Ion chromatography, which is commonly used in environmental analysis, also requires that no inorganic pollutants be introduced in sample pretreatment.

Aijiren syringe filter membrane use method introduction: before inhaling the sample, suck about 1ml of air into the syringe, so as to minimize the liquid residue, suck the sample into the syringe, invert the syringe and clear all the residues on the top Clean, connect the needle filter to the syringe, tighten it gently to ensure a good seal, filter the sample in the syringe and inject it into the sample bottle, and then follow the steps to maximize the recovery rate, remove the filter, and suck air into the syringe, Reconnect the filter head and eject all residual samples.

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.

MCE features: relatively uniform pore size, high porosity, no media shedding, thin texture, low resistance, fast filtration rate, and minimal adsorption.
The main purpose of MCE: to filter out the particles and bacteria of liquid medicine, gas, oil, beverages, sprinkles, electronic instruments, etc., and can also be used for the detection of particles and bacteria.

The PTFE syringe filter is tritium-free and has a two-way membrane support and Luer lock inlet/outlet and a safe and suitable syringe. The membrane type and pore size are printed on each filter for easy identification. All Aijiren syringe filters are 100% integrity tested and comply with ISO 9002 standards. The sterilizing filter is sterilized with gamma rays. And detect no pyrogen, no cytotoxicity.

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.

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.

A syringe filter (or wheel filter) is a single-use, membrane-based device used for the removal of particulate impurities from small (≤ 100 mL) liquid samples. Selected based upon the desired end application, disposable syringe filters are commonly used in labs for fast and efficient filtering, material purification, or even sterilization.

This nylon membrane can be used for alkaline blotting and fixation, but if fixing methods such as baking and ultraviolet rays are used, higher nucleic acid detection sensitivity can be obtained. Since the nylon membrane is a hydrophilic membrane, it does not need to be immersed in ethanol, methanol and other 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.

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.

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.

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.

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.

Use a disposable filter and a disposable sterile syringe to filter and sterilize, first suck the solution to be filtered into the syringe, and then pressure the solution into the sterile container under the filter (which contains a filter membrane with a pore size of 0.22 microns) ,This is done. If the amount of solution to be filtered is large, you can purchase a filter device with a pump.

PTFE is hydrophobic and needs to be pre-wetted before being used with aqueous solvents. Used for: corrosive solvents, strong acids, alcohols, alkalis, aromatic hydrocarbons. Not suitable for: water-based samples.

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.

Nylon membrane has high strong mechanical strength, chemical stability, can be tolerated by most organic solvents, extremely low in extractables, good thermal stability (up to 50¡ãC), natural hydrophilic and the majority of water solution filter characteristics. It more often applied to the common organic solvent HPLC mobile phase filtering.

MCE Syringe Filter is generally used to filter neutral or partial neutral aqueous solutions, and can be used as experimental sample clarification filtration, liquid chromatography injection filtration and so on. Not suitable for filtering organic solvents and strong acid and alkali solutions. This filter is for one-time use, filtering about 10 ml at a time (specifically, there is a big difference according to the impurities of the filtered liquid), and the filter membrane cannot be disassembled. 0.45¦Ìm can remove conventional impurities and some bacteria visible to the naked eye. Generally used in conjunction with the syringe.
