Thumbnail Filmstrip of Qualitative Filter Paper, Grade 01 Medium, 10-13um Retention, 90mm Circle, 100/Pk Images
Featuring a low-ash, medium-retention cellulose depth medium, this Grade 01 qualitative filter paper delivers reliable particle retention in the 10 to 13 micron range at a balanced medium filtration speed. Each 90mm circle is approximately 190um thick and is supplied 100 per box for routine laboratory clarification and qualitative analysis.
Key Filter Paper Media Characteristics
- Cellulose composition: Made of refined pulp and pure cotton linters with an alpha-cellulose content of nearly 100% for consistent, low-contamination performance.
- Medium retention and flow: Provides a 10 to 13 micron retention range with a medium filtration speed, balancing throughput and particle capture.
- Low ash content: Low-ash construction minimizes residue, making it well suited to qualitative analytical separations.
- Hydrophilic wettability: Wets readily for fast, even sample uptake during gravity and funnel filtration.
- Loading capacity: Handles routine precipitates such as lead sulfate, calcium oxalate, and calcium carbonate without rapid clogging.
Key Construction Characteristics
- Format: 90mm diameter circles in disc form.
- Nominal thickness: Approximately 190um.
- Grade: Qualitative, Grade 01 medium speed.
- Sterility: Nonsterile.
- Pack: 100 circles per box.
This Grade 01 paper maintains consistent retention and flow across routine separations, helping preserve sample integrity during clarification and analytical preparation. Its low-ash cellulose structure supports dependable, reproducible results for qualitative laboratory work.
