Grade 542 Ashless Fine Precipitate Filter, 110mm Circles (100 pcs) SKU: 1542-110

Quantitative Ashless Filter Paper - 1542-110

Gravimetric procedures in regulated laboratories require documented ash content that can be reported alongside analytical results for compliance verification. Smooth fiber surface facilitates clean precipitate release during transfer operations from funnel to crucible. Consequently, controlled manufacturing delivers the documented retention, flow rate, and physical consistency that analytical and preparative filtration methods require.

Key Filter Paper Characteristics

• Acid washing process removes metallic contaminants that could interfere with trace element determinations after ignition.
• Controlled fiber density balances rapid filtration with complete precipitate capture for efficient quantitative determinations.
• Particle retention rating of 2.7um defines the separation threshold for the application, determining which solids are captured and which pass through.
• Ash content of <0.006% provides the documented blank value specification that quantitative analytical methods require.
• Basis weight of 93g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.

If you're transitioning from qualitative screening to quantitative gravimetric work, the documented ash content above confirms this paper's suitability. Meeting this challenge, fine fiber construction provides the mechanical integrity you need to transfer collected precipitates to the crucible without sample loss. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
