Slow-Speed Qualitative Filter Paper 2–3 μm Whatman 5 Equivalent
Fine-pore filter paper with low ash content. Retains very fine precipitates where coarser grades are ineffective. Direct equivalent to Whatman 5.
Technical Specifications
- Pore size: 2–3 μm
- Thickness: 200 μm
- Basis weight: 100 g/m²
- Ash content: Maximum 0.06%
- Filtration speed: Slow
- Equivalent to: Whatman 5
- Formats: Circles and folded
When to Use
Filters gelatinous or very fine precipitates that clog larger-pore papers. Common applications include gravimetric analysis, water quality control, and sample preparation in chemistry laboratories.
The logical step up when standard-pore grades are insufficient. Slow filtration speed extends throughput time—retention is near-complete for particles above 2 μm.
Format and Compatibility
Available as circles for standard funnels and pre-folded ready for immediate use. Low ash content makes it suitable for applications involving paper incineration.
