Grade 93 Qualitative Filter Paper Wet-Strengthened, 110mm, 50 Envelopes of 25 Circles, 1250 Pk SKU: 1093-111

Qualitative Filter Paper - 1093-111

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. To this end, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Standard qualitative cellulose filter paper provides reliable particle retention for gravity and vacuum filtration across routine laboratory workflows.
• Smooth surface finish supports clear visual inspection of retained material and clean separation from the collected filtrate.
• Standard basis weight and thickness specifications provide predictable packing density for volumetric calculations in gravity funnels.
• Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
• Available in precut circles and sheet stock to match funnel sizes and custom cutting requirements across laboratory applications.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. To address this, sheet-to-sheet consistency means your training investment carries forward as new staff learn the same predictable filtration behavior. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
