Overview
Resource

VWR® Qualitative Filter Papers are high-purity, cellulose-based filtration media designed for routine laboratory applications requiring reliable and reproducible qualitative analysis. Manufactured from nearly 100% alpha-cellulose fibers and produced under strict quality control standards, these filter papers deliver consistent filtration performance across a wide range of analytical workflows.

With a low ash content of approximately 0.06%, VWR qualitative filter papers are ideal for general laboratory filtration tasks where minimal residue is required but ashless-grade precision is not critical. Their optimized pore structures and mechanical strength ensure efficient separation of precipitates, particulates, and suspensions in chemistry, pharmaceutical, clinical, food, and environmental laboratories.

Available in multiple grades with varying retention rates and flow speeds, VWR qualitative filter papers provide tailored solutions for coarse, medium, and fine filtration applications.

Key Features

High Purity Cellulose Composition
Manufactured from nearly 100% alpha-cellulose, ensuring consistent filtration quality and chemical compatibility.
Low Ash Content (~0.06%)
Minimizes residue after filtration, making them suitable for most qualitative analytical procedures.
Wide Range of Filtration Grades
Multiple grades available to support coarse, medium, and fine particle retention requirements.
Optimized Flow Rates
Designed to balance filtration speed and retention efficiency for different laboratory workflows.
Mechanical Strength & Wet Stability
Maintains integrity during filtration, even when handling gelatinous or heavy precipitates.
Binder-Free Construction (Selected Grades)
Ensures minimal interference with sensitive analytical procedures.
Versatile Formats and Sizes
Available in circular sheets and rolls, compatible with standard laboratory filtration setups.
