Porosity Range 2µm - 25µm (Grade Dependent) Ash Content Qualitative & Ashless Grades Material Base Alpha Cotton Cellulose Flow Velocity Slow to Extra-Fast Professional Filter Papers are fundamental to separation science, providing the necessary medium for removing precipitates and clarifying liquids in analytical chemistry. At Labend Scientific, our Advanced Filtration Catalog includes premium qualitative and quantitative grades, such as the industry-standard Whatman Grade 1. These papers are manufactured from high-purity cellulose linters, ensuring zero leaching and consistent particle retention. In quantitative analysis, where the purity of the sample is measured by a Digital Spectrophotometer, using ashless Grade 2 Filter Paper is essential to prevent mineral interference. For large-scale laboratory operations, we provide Filter Paper Reels that allow researchers to cut custom sizes for specialized funnels. Microbiological labs often utilize these papers to filter growth media before plating in Radiation Sterilized Petri Dishes or Glass Petri Dishes. Whether you are performing routine gravity filtration or vacuum-assisted separation, our papers maintain structural integrity even when wet. For clinical applications involving Blood Collection Tubes, filtration ensures the removal of fibrin clots. All processes should be conducted while wearing Tarsons Safety Gloves to avoid contamination from skin oils. From 185mm Discs to specialized reels, Labend Scientific provides the complete spectrum of Laboratory Consumables to support your research. Filtration Intelligence FAQ Q1: Difference between Qualitative and Quantitative? Qualitative papers are for general identification, while Quantitative (ashless) papers are used for gravimetric analysis where the filter is burned off. Q2: What does Grade 1 signify? Grade 1 is the most widely used filter paper for routine applications with medium retention (11µm) and medium flow rate. Q3: Can these papers be used for air sampling? Yes, cellulose filter papers are often used in environmental monitoring to collect atmospheric particulates for later analysis. Q4: How to choose the right diameter? The paper should be slightly smaller than the funnel rim. For a 10cm funnel, a 9cm or 11cm paper disc is typically used.
