Qualitative Filter Paper, Medium-Slow, 5-8um Retention, 185mm Circle, 100/Pk
GVS SKU: FP185DMS03QLTC01

Featuring a thick, low-ash cellulose medium made from refined pulp and pure cotton linters, this 185mm qualitative filter paper delivers medium-slow filtration with a 5 to 8um particle retention range. The extra-thick sheet provides excellent loading capacity and increased wet strength, making it well suited to liquids that are hard to clarify. Supplied nonsterile in a pack of 100 circles.

Key Cellulose Media Characteristics

• Hydrophilic cotton linter cellulose with near 100% alpha-cellulose content for clean, consistent filtration.
• Medium-slow filtration speed paired with fine 5 to 8um particle retention for clarifying difficult samples.
• Double-thickness construction provides high solute loading capacity so more precipitate can be held without clogging.
• Increased thickness gives added wet strength for reliable handling during filtration.
• Low ash content keeps background contribution minimal in qualitative analytical work.

Key Construction Characteristics

• Material: cellulose (cotton linter), GVS grade DMS03.
• Format: 185mm diameter circle.
• Retention range: 5 to 8um, medium-slow flow.
• Supplied nonsterile, 100 circles per box.

This grade maintains consistent porosity and predictable retention across the sheet, supporting reproducible results in routine laboratory filtration. Its thickness and loading capacity make it dependable for essences, oils, tinctures, and other liquids that are difficult to clarify, while the low-ash cellulose helps preserve sample integrity.

• Clarification of Difficult Liquids Medium-slow flow and 5-8um retention clarify essences, oils, and tinctures that are hard to filter.
• Fine Precipitate Filtration The fine retention range captures finely divided precipitates in qualitative analytical separations.
• Buchner Funnel Filtration The thick, high-wet-strength sheet performs reliably under vacuum in Buchner funnel setups.
• Atmospheric Contaminant Monitoring Suited to collecting and monitoring specific contaminants from air sampling.
• Soil Testing Provides consistent retention for soil analysis and related environmental sample preparation.
• High-Load Sample Prefiltration Excellent loading capacity holds more particulate without clogging when processing heavily loaded samples.
