0.22 PVDF Syringe Filter
Aijiren’s syringe filter with PVDF membrane has a wide range of chemical compatibility, making it an ideal choice for filtering general biological samples and solvent-based proteins, alcohols, peptides, aqueous samples and tissue culture media. Aijiren’s Syringe filter can be used directly without sterilization in order to allow customers to obtain higher efficiency. In order to filter the particles correctly, you need to find the right size filter. You should choose the diameter of the filter carefully. Their dimensions are usually 13 mm and 25 mm. The pore size is usually divided into 0.22 and 0.45. The 13 mm diameter syringe filter can be used for 1-10 ml samples. The 25 mm PVDF syringe filter can be used for sample volumes of 10-100 ml. Their retention is less than 100 ml.
The PVDF membrane produced by Aijiren has pore diameters of 0.22μm and 0.45μm. The PVDF Syringe Filter in the picture is 0.22μm, which is suitable for most western blots, especially for proteins with a molecular weight of less than 20kDa, which can effectively reduce the leakage of small molecular weight proteins. This product has higher protein adsorption rate and protein sequencing yield than 0.45μm PVDF membrane. For example, the adsorption capacity of insulin and BSA are 1.64 times and 1.58 times that of the commonly used 0.45μm PVDF membrane, respectively.
