Quantitative Ashless Filter Paper, Medium, 8 um, 70mm, 100/Pk SKU: CF15012

Quantitative Ashless Filter Paper - CF15012

Analytical laboratories performing routine gravimetric work need filter paper with consistent, documented ash values across every production lot. Accurate mass-based determinations start with a filter medium whose residue after ignition is controlled, tested, and traceable. In effect, quality-controlled production produces filter paper with the documented consistency that reproducible analytical and preparative methods demand.

Key Filter Paper Characteristics

• Manufactured under controlled acid washing conditions, each sheet delivers consistent ash levels across production lots for method reproducibility.
• Designed for gravimetric determinations where the filter paper is ashed or ignited as part of the analytical measurement step.
• Nominal basis weight of 80±5g/m² reflects the fiber density that determines flow rate, retention, and mechanical handling characteristics.
• Ashless filter paper provides the documented low residue needed for ignition-based analytical procedures where filter mass affects results.
• Acid-washed cellulose construction produces ash content below 0.01%, meeting the blank value requirements of quantitative gravimetric methods.

When your budget requires balancing performance with cost efficiency, the documented consistency above ensures you're not paying for premium features you don't need. In particular, documented ash specifications on every lot give you the traceability your regulated analytical methods and quality audits require. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
