Syringe filter is a small, disposable device used for filtering liquids or gases.It consists of a plastic housing with a membrane filter at one end and a female luer lock or luer slip connection at the other end, which allows it to be attached to a syringe or other fluid delivery system.
Syringe filters are commonly used in laboratory and research settings to remove particles, microorganisms, or other impurities from samples before analysis or further processing. The membrane filter in a syringe filter acts as a barrier, allowing only the desired components of the sample to pass through while retaining any larger particles or contaminants.
The choice of membrane material depends on the nature of the sample and the substances to be filtered.

 In HPLC analysis and IC analysis, syringe filters can be used to filter sample solutions, which is an important step in sample pretreatment.

The Lab Use Syringe Filter MCE is a versatile filtration tool designed for laboratory applications. Constructed with high-quality mixed cellulose ester (MCE) material, these syringe filters offer excellent chemical compatibility and durability. They effectively remove particulates, microorganisms, and impurities from liquid samples, ensuring enhanced sample purity for accurate analysis.

The MCE membrane filter provides researchers with the lowest combined filter. Due to their extremely low binding characteristics, these filters provide higher throughput than competing products and reduce filter replacement when filtering protein solutions.

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.
In addition, chromatography commonly used in environmental analysis requires that no inorganic contaminants be introduced during sample pretreatment.

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.

Compared with Nitrocellulose membrane (NC membrane), PVDF membrane has many advantages. PVDF membrane 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 membrane can be repeatedly tested after proper treatment.

Customers can use sterile syringe filters to filter out particles and contamination in the fluid. Filtration requires a 0.2¦Ìm pore size to produce a sterile filtrate. The volume of the solution to be filtered varies from a few milliliters to several liters. Typical fluids may include serum-containing media, buffers, biological or protein samples, reagents, or other fluids, and need to be free of particulates or microbial contamination.

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.

Low protein binding rate: These filters have a low protein binding rate. When the sample is less bound, its fluidity increases, and it also has better diffusion properties. Samples purified with PES filters can produce better results by tolerating slight changes in their density-related properties.
