High Absorption Qualitative Filter Paper 1 Box 9-11cm Slow Medium Fast for Laboratory Test Water Quality Detection Work

Description: Premium 9cm-11cm Qualitative & Quantitative Filter Paper Set, crafted from top-grade refined wood pulp, perfectly meets the demands of reliable laboratory filtration, chemical analysis, and daily liquid filtration. Features: 1. High Purity Filtration Performance: Made of premium refined wood pulp with ultra-low ash content, no extra impurities will be released during the whole filtration process, ensuring highly accurate and stable test results for all types of precision analysis experiments. 2. Stable Consistent Filtration Efficiency: Uniform micropore structure formed by professional pulping process delivers steady filtration speed and reliable particle retention rate, effectively avoids filtration deviation and reduces the cost of repeated tests for users. 3. Excellent Wet Strength Performance: Specially reinforced wood pulp fibers can maintain complete structure without breaking or deforming even when fully soaked in various liquids, supports long-term vacuum and pressure filtration operations, and improves long-time use experience. 4. Standard Precision Cut Size: All filter papers are processed with precision cutting technology, 9cm-11cm standard diameter with neat burr-free edges, fits most regular laboratory funnels perfectly, easy to fold and place, and prevents liquid leakage during filtration. 5. Dual Type for Versatile Use: Two types of filter paper are produced with differentiated processing technology. Quantitative filter paper is for gravimetric analysis tests, and qualitative filter paper is for general filtration and qualitative detection, which meets varied demands of lab experiments, industrial testing and daily DIY filtration scenarios. Specifications: Category: Laboratory Filtration Supplies Material: High-grade Refined Wood Pulp Size: 9cm-11cm in Diameter Color: White (filter paper); Green, Yellow (outer packaging) Application: Laboratory chemical analysis, industrial impurity detection, food testing, daily liquid filtration (coffee, homemade essential oil, etc.) Quantity: 1 Box Note: 1.
