The filter’s core benefit is its enhanced consistency and reliability. It is a certified Grade 2 filter and is guaranteed to meet the stringent weight requirements of ASTM E 2187-09, simplifying your testing process and ensuring traceability. With a medium porosity and medium flow rate, it is also widely used for monitoring specific atmospheric contaminants and various soil testing procedures. For high-volume processing, a prepleated (Grade 2V) version is available to provide improved flow rate and increased loading capacity.
Features:
- Slightly increased retention (8 µm) and greater absorbency compared to Grade 1 filter paper
- Certified to meet ASTM E 2187-09 weight requirements for consistent quality
- Medium porosity and medium flow rate for general qualitative analytical separations
- Used for monitoring specific atmospheric contaminants and soil testing procedures
- Available in a wide range of diameters and prepleated (Grade 2V) formats for increased loading capacity
