Grade CFP44 Quantitative Ashless Cellulose Filter Paper, 3µm, 150mm, Slow Flow, 100/Pk SKU: LE-CFP44-150

Featuring acid-washed quantitative cellulose construction delivering exceptional analytical precision for gravimetric analysis applications requiring separation of very fine precipitates. This grade demonstrates a slightly wider retention rate within a similar flow rate compared to CFP42, providing approximately 3µm retention while maintaining the slow flow characteristics essential for precise analytical procedures. Ultra-low ash content below 0.01% ensures contamination-free results in critical quantitative determinations and spectrophotometric sample preparation.
