PTFE syringe filters are made of Polytetrafluoroethylene (PTFE) membrane and a polypropylene overmold housing.

These syringe filters feature a user-friendly design that allows for easy and efficient filtration. They are compatible with standard luer-lock syringes, providing a secure and leak-free connection. The nylon membrane has a small pore size, typically ranging from 0.2μm to 0.45μm, enabling efficient removal of contaminants while retaining the desired analytes. The filters provide high flow rates and low protein binding, making them suitable for a variety of sample types.

A syringe filter is a disposable filtration device that is attached to a syringe for the purpose of filtering or clarifying liquid samples.
It consists of a plastic housing with a membrane filter that allows for the removal of particles or contaminants from the sample as it passes through the filter.
Syringe filters are widely used in research laboratories, quality control laboratories, pharmaceutical industries, biotechnology companies, and other applications where the filtration of liquid samples is necessary.

The Sterile syringe filter produced by Aijiren is a single-use membrane-based filtration facility that is mostly used to remove particulate impurities from liquid and gas samples before analysis by HPLC, ion chromatography, gas chromatography, ICP, and dissolution testing methods. . Correctly filtering samples in chromatographic experiments can improve the quality and consistency of analysis results and reduce instrument downtime. The sterile syringe filter adopts high-temperature aseptic processing and vacuum packaging of liquid to ensure the cleanliness of the syringe filter. It is recommended to be used once.

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.

Nylon has excellent flow characteristics, extremely low extractable level and mechanical stability, and can provide the best combination of physical parameters to meet the most stringent analysis requirements of 13mm, 25mm and 33mm diameters. Nylon’s natural hydrophilicity, high protein binding capacity and high dirt adsorption capacity are natural advantages.

Adding a syringe filtration step before the sample injection not only helps to ensure more consistent and reliable results. It also helps protect delicate instruments and extend column life.

In chromatographic experiments, the sample is placed on the chromatographic column for analysis after the sampler is injected. However, the inner core of the sampler and the chromatographic column is relatively thin. If there are large particles in the sample, it may cause the device to block , Need to use Syringe Filter for preliminary sample filtration treatment.

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.

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.

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.

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.

In HPLC analysis, the particle size of the chromatographic column packing is small and easily blocked by contaminant particles. t. In HPLC analysis and IC analysis, syringe filters can be used to filter sample solutions, which is an important step in sample pretreatment.

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.

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.

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.

Features of MCE: uniform pore size, thin texture, low flow resistance, high filtration speed, low absorption, all items are quality tests for filter efficacy and housing integrity.

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.

Compressed sterile air filters can be used to create clean rooms free of bacteria and other harmful particles for people with compromised immune systems. Each air supply pump is also equipped with a sterile air filter to ensure the delivery of pollution-free air. These air filters are usually sterilized by gamma rays and packaged separately.

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.
