Product Overview
Whatman Grade 50 cellulose filter paper is engineered for medium particle retention, making it a versatile choice for routine laboratory filtration tasks. Manufactured from high-quality alpha cellulose, this filter paper undergoes an acid-washing process to ensure low ash content and minimal extractables, guaranteeing purity in critical applications. Its consistent porosity and uniform thickness provide reliable flow rates while maintaining structural integrity even under moderate pressure. The medium retention range (8-12 ?m) effectively captures fine particulates without premature clogging, balancing efficiency and throughput. This filter paper is compatible with a wide range of solvents and aqueous solutions, maintaining chemical stability across diverse protocols. Its smooth surface minimizes fiber shedding, reducing contamination risks in sensitive analyses. Available in multiple diameters and sheet sizes, it adapts to various filtration setups from small-scale experiments to bulk processing. The acid-washed treatment enhances wet strength, making it suitable for both qualitative and semi-quantitative applications where precision matters.
FAQs
1. What is the particle retention range for Whatman Grade 50 filter paper?
This filter paper offers medium retention in the 8-12 ?m range, making it suitable for capturing fine particulates while maintaining good flow rates.
2. Can this filter paper be used with organic solvents?
Yes, Whatman Grade 50 is compatible with most organic solvents and aqueous solutions, though pre-wetting may be required for some applications.
3. How does the acid-washing process benefit this filter paper?
The acid-washing treatment reduces ash content and extractables, improving purity for sensitive applications and enhancing wet strength.
4. What?s the difference between Grade 50 and other Whatman grades?
Grade 50 offers medium retention (8-12 ?m), while grades like 40 (coarse) or 42 (fine) target different particle sizes for specific filtration needs.
