This product is developed for laboratory filtration applications requiring reliable separation of aqueous solutions. The Shanghai Xingya water-based mixed cellulose ester (MCE) microporous filter membrane is available in multiple pore sizes, ranging from 0.22 µm to 2 µm, with a standard 50 mm diameter for compatibility with common filtration apparatus. The material offers balanced porosity and wettability, making it suitable for biological fluid clarification, particle removal, and microbiological analysis in research and quality control settings. Each box contains 50 sheets, with consistent thickness and pore distribution across the membrane. The water-based formulation ensures low extractables and reduced interaction with aqueous solvents, supporting reproducible results in routine filtration workflows.
