Product Overview
Whatman Grade 3236 cellulose filter paper is engineered for superior filtration performance in laboratory settings. Manufactured from high-purity cellulose fibers, this grade offers exceptional wet strength and retention efficiency, making it a reliable choice for demanding filtration tasks. The 110x20MM sheets provide a large surface area for efficient processing, while the uniform pore structure ensures consistent flow rates and particle capture. Its chemical compatibility with a wide range of solvents and reagents enhances its versatility across various protocols. The paper’s smooth surface minimizes fiber shedding, reducing contamination risks in sensitive applications. With its balanced combination of retention capacity and flow speed, Grade 3236 delivers reproducible results in both qualitative and quantitative analyses. The pack of 1000 sheets offers cost-effective bulk supply for high-throughput laboratories. Each sheet maintains dimensional stability even when wet, preventing tearing during handling. This filter paper meets stringent quality standards, ensuring lot-to-lot consistency for reliable experimental outcomes. The natural cellulose composition provides an inert filtration medium that won’t interfere with analytical results. Its medium retention range makes it suitable for filtering fine precipitates while maintaining good flow characteristics.
FAQs
1. What is the particle retention range for Whatman Grade 3236 filter paper?
This grade typically retains particles in the 3-5 micron range, making it suitable for medium-fine filtration applications where both retention and flow rate are important considerations.
2. Can this filter paper be used with organic solvents?
The cellulose composition provides good compatibility with most common organic solvents, though prolonged exposure to strong acids or bases may affect the paper’s integrity over time.
3. How does Grade 3236 compare to other Whatman grades?
Compared to Grade 1, it offers higher wet strength and faster flow rates, while providing finer retention than Grade 4. It’s positioned between qualitative and quantitative grades in terms of performance characteristics.
4. What’s the recommended storage method for these filter papers?
Store in original packaging in a cool, dry environment away from direct sunlight and chemical fumes. Keep sealed when not in use to prevent contamination from airborne particles.
5. Are these filter papers pre-sterilized?
These come as non-sterile sheets. For sterile applications, autoclaving at 121°C for 15 minutes is recommended, though this may slightly alter the paper’s filtration properties.
