Aijiren lab membrane syringe filter is the best choice.

You can choose a PTFE needle-punched filter to improve the filtration efficiency in any area. They provide high-performance filtration through an application-centric design and can be used in various industries that process organic samples.

Disposable syringe filter devices are designed to provide fast and efficient filtration, premium quality and economy. The membrane could be PTEF, PVDF, PES, Nylon, MES, PP, CA, and can be suitable for different situations.

Syringe filters are a fast, convenient and reliable filter tool that is routinely used in laboratories. No need to replace membranes or clean filters, which eliminates the need for complex and time-consuming preparations. Widely used in pre-sample filtration, particle removal, and aseptic filtration of liquids and gases. This method is suitable for rinsing small samples before loading into HPLC and GC, and is often used in disposable syringes.

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.

Aijiren PVDF filters are high defined pore structure, low nonspecific binding, compatible with organic and aqueous solvents. Please note that Hydrophilic PVDF syringe filters are not compatible with majority of strong acids and caustic solutions, such as dimethyl sulfoxide, dimethylformamide (DMF), acetone, ketones, esters, and ethers.

The Syringe Filters are suitable for a wide range of applications in pharmaceutical, biotechnology, environmental, and research laboratories. From sterilizing and clarifying liquids to removing particulates prior to analysis, these filters are versatile tools that can enhance the quality

The 0.22um 0.45um Lab Use Reusable Syringe Filter With Printing finds application in diverse laboratory settings. It is suitable for pharmaceutical research, biotechnology, environmental analysis, food testing, and other scientific research fields.

Hydrophilic nylon membranes have extremely low levels of extractables and contain no wetting agents. They offer good chemical resistance and are ideal for aqueous and most organic samples. Filters are Triton-free and have a bidirectional membrane support and luer lock inlet/outlet for a secure fit to the syringe. Membrane type and pore size are printed on each filter for easy identification. All Cole-Parmer syringe filters are 100% integrity tested and manufactured in accordance with ISO 9002 standards. Sterile filters are sterilized by gamma radiation. They are certified nonpyrogenic, noncytotoxic, and are blister packed.

The Non-sterile Disposable Syringe Filter is a versatile filtration device used in laboratories for sample preparation and clarification. It consists of a polypropylene housing with a membrane filter, providing efficient filtration of particulate matter and microorganisms. These syringe filters are available in various pore sizes and diameters to suit different filtration needs, and they come in non-sterile packaging.

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.

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.

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.

Uniform aperture,Thin texture,Low flow resistance,High filtration speed,Little absorption,All items are quality tests for filter efficacy and housing integrity. The housing is pressure tested for use with up 75 psig (5.0 bar) of pressure.

PES syringe filter membrane has the characteristics of high mechanical strength, it can handle high temperature liquid, and has a large flow rate (better than PTFE), and low protein binding force. With these functions, PES syringe filters can provide excellent performance for biological samples and culture media. The usable pH range is about 3-14.

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

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.

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.

Filter sterilization, that is, removing microorganisms by physical means such as screening or filter material adsorption, is a commonly used method of sterilization. The filtration method is widely used, and some materials that need to be sterilized cannot be heated, such as many vitamin solutions. In addition to being used in the production of beverages and drugs, the air is often sterilized by filtration. When we usually do microbiology experiments, the sterilized container is usually plugged with cotton at the outlet, which is actually filtering to remove microorganisms in the air, so that there is no microbial contamination in the air entering the container.

PVDF syringe filters are made of hydrophilic PVDF membrane and a polypropylene overmold housing. Available in 13 mm and 25 mm diameters and 0.22 μm and 0.45 μm pore sizes.

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.

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.
