Aijiren lab membrane syringe filter is the best choice.

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.

With PES syringe filter membrane mechanically strong character, it can handle high-temperature liquids, with great flow rate (better than PTFE), and low protein binding. With these features, PES syringe filters offer superior performance for use with biological samples and media culture. Workable pH range ~3-14.
Nylon: Nylon membrane filters are hydrophilic, flexible, tear-resistant, and autoclavable. They are resistant to a range of organic solvents and suitable for use with high pH samples. Nylon binds proteins. Unsuitable for acidic solutions. pH range ~3-14.
MCE (Mixed Cellulose Ester) syringe filters are an ideal choice when biological samples are involved. Mixed Cellulose is a hydrophilic membrane offering both low protein binding coefficients and exceptional flow rates.

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 Tech’s syringe filters are a complete range of non-sterile disposable syringe filters for reliable sample preparation. Repeatable membrane quality and automated production processes ensure that particles are removed from each sample, extend the service life of the analytical column, and minimize damage to the inlet or valve.

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.
