Product Overview
The Whatman MP31 ST membrane filter is engineered for high-performance filtration in laboratory settings, offering exceptional purity and reliability. Constructed from mixed cellulose esters (MCE), this filter ensures consistent particle retention and microbial removal, making it a trusted choice for critical applications. The 0.45?m pore size provides optimal balance between flow rate and filtration efficiency, suitable for aqueous and mild organic solutions. Its smooth surface minimizes particle binding, ensuring accurate results in analytical procedures. The filter?s uniform structure and high tensile strength prevent tearing during handling, while its compatibility with standard filtration systems enhances ease of use. Whether used in research, quality control, or routine lab work, the Whatman MP31 ST delivers reproducible results with minimal extractables. Its sterile packaging maintains integrity until use, reducing contamination risks. Designed for versatility, it supports a wide range of protocols without compromising performance. This filter is an essential tool for laboratories prioritizing precision and reproducibility in their filtration processes.
FAQs
1. What is the chemical compatibility of the Whatman MP31 ST membrane filter?
This filter is compatible with aqueous solutions and mild organic solvents, but avoid strong acids, bases, or aggressive organic solvents that may degrade the mixed cellulose esters.
2. Can this filter be autoclaved for sterilization?
Yes, the Whatman MP31 ST membrane filter can be autoclaved at 121?C for 15?20 minutes without compromising its integrity or performance.
3. Are there alternatives to the MP31 ST for higher flow rates?
For applications requiring faster flow rates, consider Whatman?s nylon or PES membrane filters, which offer higher throughput while maintaining filtration efficiency.
4. How should unused filters be stored to maintain sterility?
Store the filters in their original packaging at room temperature (15?30?C) in a dry, clean environment, away from direct sunlight and moisture to preserve sterility.
5. Is this filter suitable for protein binding studies?
The MP31 ST has low protein binding properties, but for minimal adsorption, PTFE or PVDF membranes are recommended for protein-sensitive applications.
