0.22 ΜM 47mm Hydrophilic PVDF Cut Disc Membrane Filters For Biomedical Research

Membrane filtration before separation via liquid chromatography is a crucial step in ensuring the purity and accuracy of downstream mass spectrometric analysis. This process involves using a membrane filter to remove any contaminating particles from the solvents and mobile phases, which can significantly extend the lifespan of the column and prevent system failure. By removing these impurities, samples become pure and free from any unwanted substances that could otherwise interfere with the analysis.

PVDF Cut Disc Membrane Filters from XINNA are plain white filters made of premium polyvinylidene fluoride materials. They are naturally hydrophobic but we are highly specialized in processing them into hydrophilic type to cater to more diverse needs. One of the most common applications of PVDF membranes is in biomedical research. These membranes offer a range of benefits that make them ideal for use in this field. For example, they provide high flow rates and throughput, which allows for efficient sample processing. PVDF filters also exhibit very low protein binding, minimizing interaction with the sample and maximizing its recovery. In addition, PVDF membranes are highly solvent and heat resistant, making them suitable for a wide range of experimental conditions.

PVDF membrane filter discs from us come in a variety of pore sizes and can be tailored to suit different application needs, available porosities including 0.1μm, 0.22µm, 0.45μm, 0.65μm, 0.8μm,1.2μm etc. And Industry standard diameters of 13, 25, 47, 90, 142, 293mm all available.

When it comes to instructions for use, sterilizing the filtration of a liquid through PVDF membrane filter discs with 0.22µm porosity is an effective way for sterilization, removal of biological contaminants and complete bacterial retention. For more general applications, where larger biological contaminants need to be retained, liquid filtration through PVDF membranes with 0.45 μm (or larger) pore sizes may be used to trap and support microorganism growth for subsequent culture and analysis.

Packing and Shipping

Membrane disc filters are properly packaged in polyester bags or cases with quantity and label specified as requested by customer. Each pack is then safely sealed before put into a carton, and surrounded by protective air bag in the carton to avoid possible damange during ground, air, or Water Shipping.
