Grade 540 Ashless General Lab Filter Paper, 110mm Circles (100 pcs) SKU: 1540-110

Quantitative Ashless Filter Paper - 1540-110

Methods specifying filter ignition with collected precipitate demand ash contributions that remain negligible and predictable across production lots. Each production lot is tested for ash content and documented with a certificate to support analytical traceability requirements. Consequently, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Ashless filter paper provides the documented low residue needed for ignition-based analytical procedures where filter mass affects results.
• Designed for gravimetric determinations where the filter paper is ashed or ignited as part of the analytical measurement step.
• Smooth surface finish facilitates complete precipitate recovery and clean separation from the paper during transfer operations.
• Nominal ash content of <0.006% ensures minimal inorganic residue after ignition, protecting the accuracy of gravimetric determinations.
• Tightly controlled manufacturing produces documented ash content that remains consistent across production lots for method reproducibility.

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. 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.
