Grade 50 Filter Paper, Thin, 55mm Circle, 100/Pk SKU: 1450-055

Quantitative Ashless Filter Paper - 1450-055

Classical analytical methods requiring filter ignition with collected precipitate demand documented ash values verifiable through every production lot. Fine fiber matrix delivers the mechanical integrity needed to transfer collected precipitates from funnel to crucible without loss. Accordingly, standardized manufacturing protocols produce papers with retention and flow characteristics that remain constant from the first batch to the last.

Key Filter Paper Characteristics

• Controlled fiber density balances rapid filtration with complete precipitate capture for efficient quantitative determinations.
• Manufactured under controlled acid washing conditions, each sheet delivers consistent ash levels across production lots for method reproducibility.
• Ashless filter paper provides the documented low residue needed for ignition-based analytical procedures where filter mass affects results.
• Wet-strengthened construction provides the mechanical durability needed for technical filtration applications under sustained vacuum.
• Hardened surface treatment increases wet strength and chemical resistance for demanding analytical procedures.

If your workflow includes both routine clarification and specialized quantitative methods, stocking this versatile grade reduces your inventory complexity. Documented ash specifications on every lot give you the traceability your regulated analytical methods and quality audits require. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
