Product Overview
The Whatman ME27 Membrane Filter is engineered for superior performance in laboratory filtration applications, offering exceptional clarity and reliability. Constructed from high-quality mixed cellulose esters, this 0.8?m pore size filter delivers consistent particle retention while maintaining optimal flow rates. Its uniform structure ensures minimal extractables, making it ideal for sensitive analytical procedures where purity is paramount. The ME27 membrane is designed to withstand a wide range of chemical compatibility, including aqueous solutions and mild organic solvents, without compromising integrity. Its smooth surface minimizes particle adsorption, ensuring accurate results in critical filtration tasks. The filter’s robust construction provides mechanical strength during handling and processing, reducing the risk of tears or deformation. Each disc undergoes rigorous quality control to meet strict laboratory standards, guaranteeing batch-to-batch consistency. The hydrophobic nature of the membrane allows for efficient wetting with low-surface-tension liquids, expanding its versatility across different applications. With its balanced combination of retention efficiency and flow characteristics, the Whatman ME27 represents a cost-effective solution for routine laboratory filtration needs while maintaining the precision required for research applications.
FAQs
1. What is the chemical resistance profile of Whatman ME27 filters?
The ME27 membrane demonstrates good resistance to aqueous solutions, dilute acids, and mild organic solvents. For specific chemical compatibility, refer to the manufacturer’s chemical resistance chart.
2. Can these filters be autoclaved for sterilization?
Whatman ME27 filters can be autoclaved at 121?C for 15 minutes, though repeated autoclaving may affect performance. Consider gamma irradiation for multiple sterilization cycles.
3. How does the ME27 compare to PTFE membranes for protein binding?
ME27 membranes exhibit lower protein binding compared to PTFE due to their cellulose ester composition, making them preferable for protein-containing solutions.
4. What’s the recommended storage condition for unused filters?
Store filters in their original packaging at room temperature (15-30?C) in a dry environment, away from direct sunlight and volatile chemicals.
5. Are these filters suitable for air monitoring applications?
While primarily designed for liquid filtration, ME27 filters can be used for particulate air monitoring when properly supported in a suitable holder.
