Product Overview
The Whatman Grade GF6 Glass Microfibre Filter is engineered for high-efficiency particulate retention while maintaining exceptional flow rates, making it a staple in laboratories requiring reliable filtration. Constructed from 100% borosilicate glass microfibers without binders, this filter ensures chemical compatibility with aggressive solvents, acids, and bases, eliminating the risk of extractables that could compromise results. Its uniform fiber distribution and smooth surface minimize particle shedding, ensuring consistent performance across applications. The GF6 grade is specifically designed for applications demanding a balance between fine particle retention (1.6?m nominal) and rapid filtration, reducing processing time without sacrificing accuracy. Its thermal stability (up to 500?C) allows for sterilization via autoclaving or dry heat, while its inert nature prevents interactions with filtrates, preserving sample integrity. The filter?s mechanical strength resists tearing during handling or under vacuum pressure, ensuring durability in high-throughput environments. Whether used for clarifying liquids, monitoring airborne contaminants, or preparing samples for gravimetric analysis, the GF6 delivers reproducible results with minimal maintenance. Its compatibility with standard filtration apparatus and availability in a wide range of diameters (from 25MM to 610x620MM) accommodates diverse experimental setups, from small-scale bench work to large-volume industrial processes. The binder-free composition also makes it ideal for applications where residual organic matter must be avoided, such as in environmental testing or pharmaceutical research. Each pack is meticulously manufactured to meet stringent quality standards, guaranteeing lot-to-lot consistency for critical applications.
FAQs
1. What is the nominal particle retention size for Whatman GF6 filters?
The Whatman GF6 grade retains particles down to 1.6 micrometers, offering a balance between fine filtration and high flow rates for efficient processing.
2. Can GF6 filters be autoclaved for sterilization?
Yes, these filters are thermally stable up to 500?C, making them suitable for autoclaving or dry heat sterilization without compromising structural integrity.
3. Are GF6 filters compatible with organic solvents like acetone or methanol?
The borosilicate glass composition is chemically inert and resistant to most organic solvents, acids, and bases, ensuring compatibility across a wide range of filtrates.
4. How does the GF6 compare to GF/C or GF/D grades in terms of flow rate?
GF6 offers a faster flow rate than GF/C (1.2?m) but slightly slower than GF/D (2.7?m), making it ideal for applications where moderate retention and speed are required.
5. What is the recommended storage condition for unused GF6 filters?
Store in a cool, dry environment in their original packaging to prevent contamination from dust or moisture. Avoid exposure to direct sunlight or extreme temperatures.
