Whatman™ Grade GF/A Glass Microfiber Filters
Manufacturer: VWR International
Description
The filter’s core strength is its purity and versatility. It is binder-free, which is essential for preventing contamination in sensitive methods like radio-immunoassay (RIA). The high-quality glass microfiber is ideally suited for the rapid filtration of precipitated proteins, cells, and cell debris in biochemistry. It is also the established standard for gravimetric determination of airborne particulates and is widely used for water and air pollution monitoring. Available in a comprehensive range of diameters and sheet sizes, the Grade GF/A filter is the reliable choice for any lab requiring ultimate purity.
Features:
- Glass Microfiber material with a fine 1.6 µm particle retention at 98% efficiency
- Binder-free to ensure sample purity in sensitive assays, such as radio-immunoassay (RIA)
- Fast flow rate for rapid filtration of fine precipitates
- Established standard for gravimetric determination of airborne particulates
- Ideal for filtering precipitated proteins, cells, cell debris, and various cultures
- Available in a comprehensive range of diameters and sheet sizes
