GVS Filter Paper, Disk, 240mm, Low Ash-Medium Slow, Grade 02, 100/PK FP240DMS02QALC01

Quantitative ashless filter paper designed for critical analytical filtration and gravimetric analysis. The disc format (110 mm) provides slow flow with high retention for fine precipitates, and the hardened ashless construction delivers enhanced mechanical strength suitable for Büchner funnels and filtration under pressure. Packaged 100 per box for laboratory use, it is intended for recovery and accurate measurement of analytical precipitates where minimal ash contamination is required.

Key Features:

• Diameter: 110 mm
• Grade: 44 (Quantitative, Slow)
• Retention range: 2–4 µm
• Thickness: 160 µm
• Pack quantity: 100 discs per box
• Filtration time (distilled water): 292 seconds
• Wet bursting strength: 52 kPa

Advantages:

• Very low ash content (acid-hardened ashless construction) minimizes contamination for accurate ash-free dry mass measurements.
• Fine particle retention (2–4 µm) enables reliable capture of analytical precipitates for gravimetric analysis.
• Hardened texture and high wet bursting strength provide improved mechanical resilience for use in Büchner funnels and pressure filtration.
• Consistent manufacturer-controlled production yields reproducible filtration performance and reliable laboratory results.
