25mm Syringe Filter

The syringe filter is a fast, convenient and reliable filter tool commonly used in laboratories. Since there is no need to replace the filter membrane and filter cleaning, complicated and time-consuming preparations are eliminated. It is widely used in sample pre-filtration, particle removal, aseptic filtration of liquids and gases. It is the preferred method for filtering small samples before loading into HPLC and GC, and is usually used with disposable syringes.

A syringe filter with a hydrophobic PTFE membrane can be used to filter strong solvents, acids and alkalis. Not suitable for filtering aqueous liquids. Filters with hydrophilic polytetrafluoroethylene can be used to filter strong solvents, acids and alkalis. However, these syringe filters can also be used to filter aqueous liquids, which makes this type of use very versatile.

PVDF membrane has many advantages. PVDF film has high mechanical strength, is not easy to break or curl; it has the advantages of low background, wide solvent compatibility, and excellent coloring ability; in addition, PVDF film can be tested repeatedly after proper treatment. It has strong filtering ability and can get repeated experimental results.

The Syringe Filter produced by Aijiren uses different types of filter membranes, and different materials can be applied to different reagents and different experiments. PES Syringe Filter is a popular product because of the hydrophilicity of PES, which ensures the adaptability and stability of Syringe Filter. . The diameter of the PES Syringe Filter in the picture is 33mm, the large diameter is easy to operate, and the PES material guarantees the production quality.

There are many specifications of PP syringe filter. The diameters of 13mm and 25mm can be used for different sizes and types of syringe needles. The diameter of the filter membrane is 0.22 and 0.45, which can filter impurities of different diameters. Aijiren produces PP syringe filters. The reason is to make it easier for customers to prepare samples. Samples filtered out of impurities will not affect the autosampler injection, and can protect the chromatographic column and prevent impurities from entering the chromatographic column.

Syringe Filter membrane: HPLC certified nylon.
Used for: bases, most HPLC solvents, alcohols, aromatics, THF.
Do not use for: acids, corrosive halogenated hydrocarbons, protein samples (nylon is a high binder)
Sterilization: The syringe filter can be sterilized by an autoclave at 125° for 15 minutes.
Application: General laboratory filtration, most HPLC samples

Nylon Syringe Filter has good hydrophilicity, acid and alkali resistance, and oxidation resistance. It can be used for alkaline blotting and fixation. If fixation methods such as baking and ultraviolet light 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 a solution such as ethanol or methanol for activation. Nylon Syringe Filter is suitable for organic solvents, such as alcohols, hydrocarbons, lipids, phenols, ketones and other organic solvents. Nylon Syringe Filter can also be used for organic solvents such as strong acids, 70% ethanol, and methylene chloride. High temperature resistance, good strength, stable chemical properties.

Aijiren’s PTFE polytetrafluoroethylene is a membrane that is very suitable for filtering samples and highly corrosive substances based on gas or organic solvents. The hydrophilic PTFE membrane provides you with chemical resistance to corrosive media and excellent temperature stability, thereby expanding the sampling range. More applications of PTFE syringes are: for analysis and research applications and air sampling. Use in extreme chemistry or temperature. Used to filter non-aqueous organic solvents. It is also ideal for filtering highly aggressive colloidal solutions.

Aijiren’s PTFE syringe filter does not contain tritium and has a two-way membrane support, which is very suitable for syringes. 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 standards. PTFE (polytetrafluoroethylene) performance: suitable for water systems and various organic solvents, and resistant to all solvents, low solubility. It is breathable and impermeable, large air flux, high particle retention rate, good temperature resistance, resistance to strong acids, strong alkalis, organic solvents and oxidants, aging resistance, non-sticky, non-flammable, non-toxic and biocompatible. Its related products are widely used in chemical, pharmaceutical, environmental protection, electronics, food, energy and other fields.

Aijiren PTFE syringe filters are widely used in laboratories. It does not require membrane replacement and filter cleaning, eliminating complicated and time-consuming preparations. Mainly used for sample pre-filtration, clarification and removal of particles, and sterilization and filtration of liquids and gases. HPLC and GC are the preferred methods for small samples. Aijiren’s PTFE syringe filter housing is made of high-quality polypropylene (PP) with high mechanical strength and good chemical compatibility. The filter membrane is made of hydrophobic polytetrafluoroethylene (PTFE) and high-density polyethylene support. No binders or additives are used, and there is little interference with analysis.

Nylon has good chemical stability, flexibility, durability, not easy to tear, can withstand saturated steam autoclaving, and is suitable for filtering aqueous solutions and most organic solvents. Such as electronics, microelectronics, semiconductor industry water filtration, tissue culture media filtration, liquid medicine filtration, beverage filtration, high-purity chemical products filtration. Generally tolerate the range of PH3-14.
