GVS Filter Paper, Disk, 240mm, Low Ash-Medium Slow-Thick, Grade 03, 100/PK FP240DMS03QLTC01

Quantitative ashless filter paper in disc format designed for very slow filtration of fine precipitates and critical gravimetric work. This 110 mm, ashless, very slow filter paper is intended for quantitative analysis and analytical precipitates (for example barium sulfate and finely precipitated calcium carbonate). The paper is acid washed and processed to deliver extremely low ash content and strengthened, hardened texture suitable for Büchner funnel use and demanding laboratory filtration operations.

Key Features:

• Diameter: 110 mm
• Grade: Quantitative (Very Slow)
• Retention range: 2–3 µm
• Filtration time (distilled water): 292 seconds
• Thickness: 160 µm
• Box quantity: 100 discs

Advantages:

• Very slow flow with high retention for reliable collection of ultra-fine precipitates.
• Acid-washed, ashless construction (maximum ash content ≤ 0.006%) to avoid contamination in gravimetric analysis.
• Hardened texture and enhanced mechanical strength suitable for Büchner funnel and pressure-assisted filtration.
• Consistent, manufacturer-controlled production for reproducible analytical results.
