Grade CFP6 Cellulose Filter Paper, 3-4µm Retention, 240mm, Qualitative, 100/Pk SKU: LE-CFP6-240

Featuring high-quality cellulose fiber construction delivering 3-4µm particle retention with optimized flow characteristics for demanding separation applications. Very similar basis and thickness to CFP5, but with a slightly less retentive porosity, this medium ensures reliable particulate capture while maintaining efficient processing speeds. Material is commonly specified in environmental applications requiring precise separation of fine particulates from liquid and gas samples.

Key Cellulose Membrane Characteristics

Qualitative cellulose filter papers perform separation by entrapping particulate within the random matrix of cellulose fibers within the depth of the media
Nominal retention of particulate at 98% efficiency in liquid ensures consistent separation performance across diverse sample types
Manufactured from high-quality cotton linters providing superior structural integrity and chemical resistance
Hydrophilic surface chemistry promotes rapid wetting and uniform flow distribution throughout the filter matrix
Due to the furnish (raw materials) of this paper the ash content is higher than the balance of the qualitative line at 0.22%

Key Construction Characteristics

240mm diameter accommodates high-volume filtration protocols while maximizing sample throughput capacity
Thickness 0.177mm measured under standardized conditions using TAPPI method T411¹ ensures dimensional consistency
This media is widely used in methods requiring the determination and identification of particulate in both liquids and gas
Also this natural fiber filter paper is commonly used to clarify liquid samples removing turbidity and suspended solids
Nonsterile construction optimizes cost-effectiveness for routine laboratory and environmental monitoring applications

LE-CFP6-240 filters achieve exceptional separation performance optimized for environmental analysis, soil testing, and general laboratory clarification procedures. Outstanding chemical compatibility with most solvents and aqueous solutions maximizes your analytical flexibility when processing diverse sample matrices. Widely used for general laboratory separation and clarification applications as well as for soil analysis methods, these qualitative-grade filters deliver reliable particulate retention while maintaining the cost-effectiveness essential for high-volume testing protocols and routine environmental monitoring campaigns.
