GVS Filter Paper, Disk, 55mm, Low Ash-Very Fast, Grade 04, 100/PK FP055DXF04QALC01

Qualitative filter paper, disc form, designed for very slow filtration and high fine-particle retention in laboratory applications. It is used to clarify cloudy suspensions and for water and soil analysis, and is suited to very difficult filtration conditions and extra fine-grained precipitates such as barium sulfate or copper oxides. The product is provided as 125 mm diameter discs in a pack of 100 and delivers a maximum degree of fine particle retention for qualitative analytical separations and clarification tasks.

Key Features:

• Diameter: 125 mm
• Filtration speed: Very Slow (filtration time for distilled water: 300 seconds)
• Retention range: 3–5 µm
• Thickness: 170 µm
• Box quantity: 100 discs
• Wet bursting strength: 20 kPa
• Kind: Disc

Advantages:

• Maximum fine-particle retention for clarifying cloudy suspensions and handling extra fine-grained precipitates.
• Suitable for difficult filtration conditions commonly encountered in water, soil and certain analytical sample preparations.
• Hardened low-ash composition provides low ash content and reliable performance in qualitative analytical techniques.
• Uniform 125 mm disc format and consistent mechanical strength facilitate repeatable laboratory workflows.
