Grade CFP1 Qualitative Cellulose Filter Paper, 11µm, 70mm, Medium Flow, 100/Pk SKU: LE-CFP1-070

Featuring high-quality cellulose fiber technology delivering reliable 11µm particle retention with optimized medium flow characteristics for versatile laboratory applications. This widely used filter paper provides medium retention (11µm) and flow rate performance across diverse analytical separations, clarification procedures, and environmental monitoring protocols. Manufactured from high-quality cotton linters, which have been treated to achieve a minimum alpha cellulose content of 98%, delivering consistent bright white appearance ideal for photometric analysis and optical measurement applications.

Key Cellulose Membrane Characteristics

Traditionally used in qualitative analytical separations for precipitates such as lead sulfate, calcium oxalate (hot), and calcium carbonate
11µm retention efficiency captures medium-sized particles while maintaining optimal flow rates for routine laboratory procedures
Ash content <0.05% ensures minimal interference in analytical determinations and gravimetric procedures
Hydrophilic cellulose construction provides excellent wetting characteristics for aqueous sample processing
Consistent bright white color optimizes photometric stain intensity measurements in air monitoring applications

Key Construction Characteristics

Standard 70mm diameter accommodates universal laboratory filter holders and funnel configurations
Thickness 0.18mm provides robust handling integrity while maintaining efficient filtration performance
Agricultural applications include soil analysis and seed testing procedures with validated analytical protocols
Food industry applications for separating solid foodstuffs from associated liquid or extracting liquid
Compatible with reagent impregnation for gas detection procedures utilizing optical reflectance measurements

LE-CFP1-070 filters achieve exceptional versatility across multiple analytical disciplines, accelerating your separation workflows from environmental monitoring to food analysis. In air pollution monitoring using circles or rolls atmospheric dust is collected from airflow and the stain-intensity is measured photometrically. For gas detection the paper is impregnated with a chromogenic reagent and color formation is quantified by optical reflectance. This proven cellulose technology delivers reliable processing performance for your critical qualitative analytical applications demanding both consistent particle retention and validated analytical accuracy across diverse laboratory environments.
