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.

Generally speaking, 0.45 ¦Ìm pore size is suitable for removing particles from samples or the mobile phase solution of chromatography equipment, and 0.22 ¦Ìm is suitable for filtering microorganisms.

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.

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.

Hydrophobic PTFE (Polytetrafluoroethylene) syringe filters are suitable for gaseous and organic solutions, with excellent performance for high corrosive samples. It is possible for an extended sampling range using hydrophobic PTFE filters for wider chemical resistance to aggressive substances and outstanding temperature stability. A PTFE syringe filter is an ideal choice for filtering and de-gassing chromatography solvents.

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.

The Nylon Syringe Filter produced by Aijiren is mostly used for reagent filtration or sample preparation. Nylon Syringe Filter has different specifications. The filter membrane diameter is 13mm, 25mm and 33mm, which can be selected according to the capacity of the sample. Aijiren provides 0.22μm and 0.45. Two μm specifications are convenient for customers to choose. The Nylon Syringe Filter produced by Aijiren meets customers’ requirements and needs for product preparation.

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.

The syringe filter produced by Aijiren is the preferred method for filtering small samples before being loaded into HPLC and GC, and is usually used with disposable syringes to filter out impurities in the sample to ensure that there is no quality in the test Problems and affect the experimental results.

Sterile Syringe Filters
While the primary function of a syringe filter is to remove particulates from a liquid sample, you will select either a sterile or non-sterile filter, depending on the end application.
Sterile syringe filters are used to sterilize non-sterile solutions or clarify sterile solutions. Learn more about sterile filters by application.

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.

PP housing membrane syringe filter refers to a syringe filter wif a housing made of polypropylene (PP).

Polypropylene is a commonly used material for syringe filter housings due to its chemical compatibility, low extractables, and resistance to a wide range of solvents. PP housings provide structural support to teh filter membrane and help maintain its integrity during filtration.
These syringe filters find applications in various fields such as pharmaceuticals, biotechnology, environmental analysis, food and beverage testing, and research laboratories where precise filtration is required to ensure sample purity and integrity.

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.

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.
