Cellulose Qualitative Filter Paper, Grade 01, 10-13um Retention, 185mm, Medium, 100/Pk
GVS SKU: FP185DME01QALC01

Featuring a low-ash cellulose medium made from refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100%, this Grade 01 qualitative filter paper delivers medium retention and a balanced flow rate for routine laboratory filtration. Each circular disc measures 185mm in diameter with a nominal particle retention of 10 to 13 micrometers and a thickness of 190um, and is supplied 100 discs per box. The hydrophilic structure provides reliable clarification of liquids across a wide range of analytical and general-purpose tasks.

Key Cellulose Filter Paper Characteristics

• Refined pulp and pure cotton linter construction with an alpha-cellulose content of nearly 100% for consistent, diverse filtration properties
• Medium nominal particle retention of 10 to 13 micrometers paired with a medium filtration speed
• Low ash content of less than 0.06% that is not reduced by post-treatment, minimizing residual interference
• Naturally hydrophilic surface that wets readily for fast, even liquid passage
• Nominal basis weight of 85 g/m2 and 190um thickness supporting dependable handling and solute loading

Key Construction Characteristics

• 185mm circular disc format suited to funnels and large-area gravity filtration
• Nonsterile, supplied 100 discs per box
• Wet bursting strength of 5 kPa for handling under wet conditions

This grade maintains consistent retention and flow for clarifying liquids, filtering fine precipitates, and supporting soil, food, and educational analyses. The uniform low-ash cellulose medium preserves sample integrity and provides repeatable results across routine workflows.

Grade 1

• Clarifying Liquids Medium retention and flow rate make this grade well suited to general clarification of routine laboratory liquids.
• Fine Precipitate Filtration Effectively captures fine precipitates such as lead sulphate, calcium oxalate, and calcium carbonate in qualitative separations.
• Soil Analysis and Seed Testing Used in agricultural laboratories for soil analysis and seed testing procedures.
• Food Industry Analysis Separates solid foodstuffs from associated liquid or extracting liquid in routine food techniques.
• Air Pollution Monitoring Collects atmospheric dust from airflow for photometric stain-intensity measurement when used as circles.
• Educational Use Widely used in teaching simple qualitative analytical separations.
