GVS Filter Paper, Disk, 47mm, Low Ash-Very Fast, Grade 04, 100/PK FP047DXF04QALC01

Qualitative filter paper discs for laboratory filtration, 125 mm diameter, supplied in packs of 100. Made of refined pulp and pure cotton linters with an alpha‑cellulose content of nearly 100%, these low‑ash, medium‑porosity Grade 01 papers are designed for routine qualitative analysis and clarifying liquids. Typical applications include medium‑speed filtration of fine precipitates (e.g., lead sulphate, calcium oxalate, calcium carbonate), soil and seed testing, food analysis and educational laboratory use. Ash content is less than 0.06%.

Key Features:

• Diameter: 125 mm
• Grade: 01 (Medium filtration)
• Quantity: 100 per pack
• Retention range: 10–13 µm
• Filtration time for distilled water: 45 seconds (typical)
• Thickness: 190 µm
• Material: Refined pulp and pure cotton linters; alpha‑cellulose ≈100%; ash <0.06%

Advantages:

• Low ash content (<0.06%) minimizes residue and contamination in analytical filtrates.
• Medium retention (10–13 µm) provides versatile performance for routine laboratory separations and clarification.
• High alpha‑cellulose content and enhanced mechanical strength deliver reliable handling and consistent filtration results.
