Grade 1 Qualitative Filter Paper, Standard, 110mm Circle, 100/Pk SKU: 1001-110

Qualitative Filter Paper - 1001-110

Routine quality control filtration across multiple product lines requires a filter paper that delivers consistent retention without batch-to-batch performance drift. Natural cellulose wettability eliminates the pre-wetting step required by hydrophobic membranes in aqueous sample filtration. For this reason, certificate of conformance documentation accompanies each lot, providing traceability for quality systems and regulatory audit requirements.

Key Filter Paper Characteristics

• Untreated cellulose provides the natural wicking and absorption properties that gravity filtration methods utilize.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Manufactured from high-purity cotton linters, qualitative filter paper provides a clean filtration surface with minimal fiber shedding.
• Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.

If your laboratory supports multiple research groups with varying filtration needs, this paper's broad applicability simplifies your procurement process. In these cases, rapid wetting and uniform pore distribution reduce the setup time your operators spend preparing each filtration run. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

• Polymer Filtration - Clears particulates from polymer solutions before molecular weight determination by viscometry or GPC.
• Precipitation Recovery - Collects insoluble reaction products on the paper surface for subsequent washing and downstream analysis.
• Teaching Laboratory - Provides consistent and economical filtration media for student exercises in analytical and general chemistry.
• Beverage Testing - Filters wine, beer, and juice samples before clarity and color measurements in food quality control laboratories.
• General Clarification - Removes suspended solids from aqueous solutions by gravity filtration for routine sample preparation.
• Soil Extract Filtration - Clarifies soil slurries for nutrient and pH testing, removing fine particles that interfere with analysis.
