The 6090-1500 Qualitative Filter Paper is an essential tool for laboratories requiring precise and efficient filtration. With a diameter of 15 cm and a pore size of 4 microns, this medium flow filter paper is perfect for a variety of applications, including routine separation work and qualitative analysis. Its high purity composition, consisting of over 95% super refined alpha-cellulose and linter fibers, ensures that your results are consistent and reliable, making it an ideal choice for both research and industrial settings.

In addition to its exceptional filtration capabilities, this filter paper is specifically designed for use in the beer industry, where low iron and nitrogen content is crucial for accurate protein analysis. The 6090-1500 grade is suitable for quadrant folded or gravity flow applications, providing versatility for various laboratory techniques. However, it is important to note that while the inherent strength of the untreated grades is sufficient for routine applications, they are not recommended for vacuum work or wet handling. This makes the 6090-1500 an excellent choice for laboratories focused on maintaining high standards of purity and performance in their analytical processes.
