Thumbnail Filmstrip of Cellulose Filter Paper, Quantitative Ashless, Grade DME43, 14-17um, 150mm, Medium, 100/Pk Images
Featuring a high-purity cellulose depth medium refined from cotton linters and pulp, this Grade DME43 quantitative ashless filter paper delivers medium-speed filtration with a nominal particle retention range of 14 to 17 micrometers. Each 150mm circle is acid-washed to an extremely low ash content of less than 0.007 percent, making it well suited to gravimetric procedures where combusting the paper must leave negligible residue. Supplied 100 discs per pack.
Key Cellulose Media Characteristics
- Quantitative ashless grade with nominal ash content below 0.007 percent for accurate gravimetric work
- Medium filtration speed with a 14 to 17 micrometer nominal particle retention range
- Naturally hydrophilic cellulose matrix that captures particulate throughout the depth of the media
- Nominal thickness of 180 micrometers and a basis weight of 85 grams per square meter
- Acid-washed cellulose for high purity in critical analytical filtration
Key Construction Characteristics
- Circular disc format measuring 150mm in diameter
- Refined pulp and cotton linter cellulose construction
- Nonsterile, supplied 100 pieces per pack
- Compatible with Buchner funnels and filtration under pressure or vacuum
This grade provides a dependable balance of retention and flow for routine quantitative analysis, capturing medium-sized particulate while maintaining sample integrity. The ashless, low-residue construction supports reliable downstream weighing and instrumental measurement.
