Syringe Filter for Filtration

The Syringe Filters are suitable for a wide range of applications in pharmaceutical, biotechnology, environmental, and research laboratories. From sterilizing and clarifying liquids to removing particulates prior to analysis, these filters are versatile tools that can enhance the quality

In HPLC analysis, the particle size of the chromatographic column packing is small and easily blocked by contaminant particles. Therefore, samples and solvents must be pre-filtered to remove particulate contaminants and protect the instrument.

PTFE Syringe Filters consist of a polytetrafluoroethylene (PTFE) membrane and a polypropylene overmolded housing. Available in 13 mm and 25 mm diameters and 0.22 μm and 0.45 μm pore sizes. PTFE is the membrane of choice for use with aggressive solvents, liquids, and gases that can attack other membranes.

Selected PES syringe filters provide a cleaner sample extract by removing interfering materials and fine particles down to the rated pore size. Performing a syringe filtration step before chromatographic injection helps ensure more consistent and reliable results, and helps protect delicate instruments and extend column life.

Nylon membrane has high strong mechanical strength, chemical stability, can be tolerated by most organic solvents, extremely low in extractables, good thermal stability (up to 50¡ãC), natural hydrophilic and the majority of water solution filter characteristics. It more often applied to the common organic solvent HPLC mobile phase filtering.

Syringe filter is a small, disposable device used for filtration purposes in laboratories and other scientific settings. It consists of a plastic housing with a membrane filter at one end and a female luer lock or male luer slip connection at the other end, allowing it to be attached to a syringe.
The purpose of a syringe filter is to remove impurities, particulates, or unwanted substances from a liquid sample before it is injected or analyzed. The membrane filter within the syringe filter acts as a barrier, selectively allowing only certain particles or molecules to pass through while retaining larger particles.

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.

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.

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.

Syringe filters are made of many different types of materials. Various materials, diameters, pore sizes, and sterile and non-sterile options are on our list. These syringe filters provide excellent microfiltration performance for HPLC, water treatment, environment, biotechnology, beverage, food, pharmaceutical and other related fields.

Syringe Filters with hydrophobic PTFE membranes can be used for filtration of strong solvents, acids and alkalis. Not suitable for filtration of aqueous liquids. Filters with hydrophilic PTFE can be used for filtration of strong solvents, acids and alkalis. However, these syringe filters can also be used for the filtration of aqueous liquids, which makes this type very versatile.

Features of the syringe filter: Luer lock inlet provides a sealed syringe connection, with various filter types, porosities and diameters. Color coding is easy to identify. Rugged polypropylene shell. Can be autoclaved to 121℃ for 15 minutes. The quantity exceeds the minimum order quantity to save more.

Sterile filtration is used in many applications: serum-containing or non-serum-containing media that supports the growth of cell cultures, reagents or solutions containing sensitive components that will degrade during high temperature processing, and when there is no autoclave, filtration should be added to the sterile growth media supplement Liquid, filter samples to avoid microbial growth during storage, filter buffers, remove particulate matter and avoid microbial growth during storage, filter biological samples to be analyzed, avoid microbial contamination of expensive equipment, filter environmental samples to be analyzed, filter fermentation liquids, Further purification or analysis.
