Product Overview
Whatman Grade 1574 cellulose filter paper is engineered for high-performance filtration in laboratory settings. Made from pure cellulose fibers, this grade delivers exceptional wet strength and chemical resistance, making it ideal for challenging filtration tasks. The medium flow rate ensures efficient processing without compromising particle retention, while its smooth surface minimizes fiber release. This filter paper maintains integrity even with aggressive solvents, acids, and alkalis, providing reliable results across diverse applications. Its uniform thickness and consistent porosity guarantee reproducible outcomes in critical procedures. The 1574 grade is particularly valued for its balance between filtration speed and particle retention, offering a practical solution for routine and specialized lab work. The cellulose composition ensures compatibility with a wide range of analytical techniques while maintaining sample purity. This filter paper represents a cost-effective choice for laboratories requiring dependable filtration performance without compromising on quality or consistency.
FAQs
1. What is the maximum operating temperature for Whatman 1574 filter paper?
This grade can typically withstand temperatures up to 120?C for short periods, though prolonged exposure to high temperatures may affect performance.
2. How does the flow rate of Grade 1574 compare to other Whatman grades?
Grade 1574 offers a medium flow rate, faster than Grade 42 but slower than Grade 1, making it suitable for applications requiring balanced filtration speed.
3. Can this filter paper be used with organic solvents?
Yes, Grade 1574 demonstrates good chemical resistance to most organic solvents, though compatibility should be verified for specific applications.
4. What particle retention size does this grade typically provide?
Grade 1574 generally retains particles down to approximately 20-25 microns, though actual retention may vary based on specific conditions.
5. Is this filter paper suitable for sterile filtration applications?
While Grade 1574 offers good filtration properties, it is not inherently sterile and would require additional sterilization procedures for aseptic applications.
