Ahlstrom 9500-0900 Qualitative Filter Paper Wet-Strengthened, Grade 950, 90 mm, 100/pk

Ahlstrom Grade 950 qualitative filter paper is designed for laboratory filtration of fine particles and precipitates. It is commonly used in analytical chemistry, environmental testing, fertilizer analysis, and other laboratory procedures where reliable separation of fine solids from liquids is required.

Grade 950 filter paper provides very fine particle retention of approximately 2 µm and has a slow filtration speed. This combination allows it to capture very small precipitates while maintaining accurate analytical results.

Wet-strengthened filter paper is specially treated so it maintains structural integrity even when saturated with liquid. This added durability helps prevent tearing or fiber breakdown during filtration processes that involve vacuum, pressure, or heavy liquid loads.

The 90 mm diameter format is widely used in laboratory filtration setups, including Buchner funnels, gravity filtration systems, and vacuum filtration apparatus designed for standard filter paper sizes.

Slow filtration grades like Ahlstrom 950 allow better separation of extremely fine particles and precipitates. This improves clarity of the filtrate and helps ensure accurate analytical measurements in laboratory testing procedures.
