Product Overview
Whatman Grade 3236 cellulose filter paper is engineered for reliable performance in general laboratory filtration applications. Manufactured from high-purity cellulose fibers, this medium-speed filter paper delivers a balance of retention efficiency and flow rate, making it ideal for routine qualitative analysis. The uniform texture ensures consistent particle retention, while its chemical resistance allows compatibility with a wide range of solvents and aqueous solutions. With a nominal thickness of 180 μm and ash content below 0.06%, Grade 3236 maintains sample integrity without introducing contaminants. Its smooth surface minimizes fiber shedding, reducing the risk of sample cross-contamination during filtration processes. The paper’s wet strength and dimensional stability ensure it remains intact even under moderate pressure differentials. Whether used in gravity or vacuum filtration setups, this filter paper provides reproducible results across multiple applications. The 110x20MM size offers ample surface area for efficient filtration while fitting standard laboratory funnels. Each sheet undergoes strict quality control to meet Whatman’s exacting standards for purity and performance.
FAQs
1. What is the particle retention capacity of Whatman Grade 3236 filter paper?
This grade typically retains particles down to approximately 8-12 ?m, making it suitable for general filtration tasks where moderate retention is required.
2. Can this filter paper be used with organic solvents?
Yes, Grade 3236 is compatible with most common organic solvents including alcohols, ketones, and aliphatic hydrocarbons, though prolonged exposure to strong acids or bases may affect performance.
3. How does the flow rate compare to other Whatman grades?
The flow rate of Grade 3236 is classified as medium, faster than Grade 42 but slower than Grade 1, offering a balance between speed and retention for routine applications.
4. What storage conditions are recommended for maintaining quality?
Store in a cool, dry environment away from direct sunlight and chemical vapors. Keep the original packaging sealed when not in use to prevent moisture absorption.
5. Is this filter paper suitable for sterile filtration?
No, Grade 3236 is not designed for sterile applications. For sterile filtration, consider Whatman’s dedicated sterile-grade filters or membrane filters with appropriate pore sizes.
