GVS Filter Paper, Disk, 203x254mm, Glass Fiber, Grade FA, 1.6µm 100/PK FP203RFAFAGLFC01

Quantitative ashless filter paper disk, 110 mm diameter, Grade 40 with medium-slow filtration characteristics supplied in packs of 100. It is an ashless, hardened filter paper designed for critical quantitative and gravimetric laboratory filtration, suitable for use in Büchner funnels and pressure filtration. Typical applications include recovery and weighing of analytical precipitates and clarification of suspensions in gravimetric and quantitative analysis.

Key Features:

• Diameter: 110 mm
• Filtration speed: Medium-Slow (filtration time for distilled water ~100 sec)
• Retention range: 7–9 µm
• Thickness: 170 µm
• Box quantity: 100 discs
• Ashless (acid-hardened for extremely low ash content)

Advantages:

• Hardened, ashless composition minimizes contaminant introduction and supports accurate gravimetric determinations.
• Enhanced mechanical strength and wet bursting strength make it suitable for Büchner funnels and pressure filtration.
• Medium-slow flow and 7–9 µm retention provide reliable capture of fine precipitates while maintaining reasonable filtration times.
• Supplied in convenient packs of 100 discs for repeatable, consistent laboratory use.
