Cellulose Qualitative Filter Paper, 5-7um Retention, Medium-Slow, 125mm, Nonsterile, 100/Pk
GVS SKU: FP125DMS03QLTC01

Featuring a thick, hardened cellulose depth medium made from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100%, this grade DMS03 qualitative filter paper delivers medium-slow filtration with a nominal particle retention range of 5 to 7 microns. Each disc measures 125mm in diameter and provides a hydrophilic surface suited to clarifying liquids and capturing fine precipitates. The medium carries a nominal thickness of 320 microns and a nominal basis weight of 200 g/m2, giving it roughly double the thickness of standard medium-grade papers for greater dirt-holding capacity and wet strength.

Key Cellulose Media Characteristics

• Hydrophilic cellulose construction made from refined pulp and pure cotton linters with nearly 100% alpha-cellulose content.
• Nominal particle retention of 5 to 7 microns for capturing fine precipitates such as those found in inorganic and soil analysis.
• Medium-slow filtration speed that balances retention with throughput across routine laboratory work.
• Thick depth structure (320 microns) that increases loading capacity, wet strength, and absorbency.
• Low ash content of less than 0.06% that is not reduced by post-treatment.

Key Construction Characteristics

• Grade DMS03, medium-slow (thick) qualitative classification.
• 125mm diameter circle format supplied as flat discs.
• Nonsterile, packaged 100 discs per box.

This filter paper maintains consistent retention and flow performance across qualitative analytical separations, soil testing, and atmospheric contaminant monitoring. The high absorbency and added thickness support reliable sample handling, while the low ash content preserves sample integrity in routine identification work.

• Qualitative Analysis Supports routine qualitative analytical separations to determine and identify materials in laboratory samples.
• Fine Precipitate Filtration Captures fine precipitates with its 5 to 7 micron retention and thick, high-capacity depth structure.
• Soil Testing Suited to soil analysis procedures where moderate to slow filtration and good loading capacity are needed.
• Atmospheric Monitoring Used for monitoring specific contaminants in the atmosphere, such as collecting atmospheric dust for analysis.
• Liquid Clarification Clarifies liquids across a broad range of routine laboratory applications.
• Sample Carrier High absorbency and added thickness make it suitable as a sample carrier in collection and transport.
