Lab PTFE Syringe Filter for HPLC for Factory

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.

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 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.

Aijiren¡¯s PP syringe filter uses a hydrophobic polypropylene membrane, which has stable physical and chemical properties, good compatibility, low protein adsorption, and is suitable for filtration of aqueous solutions and most solvents. Commonly used to filter biological samples, solvents, deionized water and reduce biological load, the hydrophobic PP filter membrane is particularly good for gas filtration. The product was sterilized by dry heat at 121¡ãC for 15 minutes.

The syringe filters are designed for easy and efficient filtration of liquids and gases. They feature a syringe-like structure with an inlet and outlet, allowing for direct attachment to a syringe or other fluid delivery systems. The filters remove particulates, microorganisms, and unwanted substances, ensuring clean and clarified samples for analysis.

Aijiren brand syringe filters are HPLC certified to ensure reliable and consistent results. Water, methanol, and acetonitrile are used for testing, and HPLC is used for detection at 210 and 254 nm wavelengths. None absorbs ultraviolet light, which can provide a purer analytical background.

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 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 reinforcement ring can provide greater strength to the shell to prevent leakage and bursting (30mm product pressure is rated at 120 psi). The shell is made of solvent-resistant, low-extraction polypropylene resin, specifically selected for wide compatibility with common HPLC sample matrices. The solution can be filtered at temperatures up to 100¡ãC, which is convenient and easy to use.

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.
