Product Overview
Whatman Grade 3644 cellulose filter paper is engineered for reliable and consistent filtration in laboratory settings. Made from high-purity cellulose fibers, this grade offers a balanced combination of medium particle retention and high wet strength, ensuring durability even under demanding conditions. The paper?s uniform texture and chemical resistance make it ideal for a wide range of filtration tasks, including qualitative analysis and routine lab procedures. Unlike thinner grades, Grade 3644 maintains structural integrity when wet, reducing the risk of tearing or fiber loss during use. Its neutral pH and low extractable content minimize interference with sensitive applications, providing accurate and reproducible results. The smooth surface allows for even particle distribution, preventing clogging and ensuring efficient flow rates. Whether used in gravity or vacuum filtration setups, this filter paper delivers consistent performance, making it a trusted choice for labs prioritizing precision and reliability. The standard sheet sizes accommodate various filtration apparatus, while the bulk packaging options ensure cost-effective supply for high-volume usage.
FAQs
1. What is the particle retention capacity of Whatman Grade 3644 filter paper?
Whatman Grade 3644 filter paper has a medium particle retention capacity, typically around 8-12 microns, making it suitable for general lab filtration tasks requiring a balance between flow rate and particle capture.
2. Can this filter paper be used with acidic or alkaline solutions?
Yes, Grade 3644 is chemically resistant and compatible with a wide pH range, including mild acidic and alkaline solutions, though prolonged exposure to extreme pH may affect performance.
3. How does Grade 3644 compare to Grade 1 or Grade 42 filter papers?
Grade 3644 offers higher wet strength than Grade 1 and finer retention than Grade 42, making it a versatile middle-ground option for applications where both durability and moderate filtration are required.
4. What is the recommended storage condition for these filter papers?
Store the filter papers in a cool, dry environment, ideally in their original packaging to protect from moisture and contaminants, which could compromise filtration efficiency.
5. Is this filter paper pre-sterilized or suitable for sterile applications?
Grade 3644 is not pre-sterilized but can be autoclaved if sterile conditions are required, provided the process adheres to standard lab sterilization protocols.
