GVS Filter, Disk, CA, 0.45µm, 47mm, 100/PK 1215676

Filter paper disk for laboratory filtration, made for qualitative analytical techniques and general filtration tasks. Designed as a low-ash, very-fast flow filter circle with a creped/pleated surface to increase surface area and speed filtration. Typical applications include qualitative analysis, soil and water analysis, clarifying liquids, and air monitoring.

Key Features:

• Diameter: 55 mm
• Pack quantity: 100 per pack
• Filtration rate: Very fast (creped/pleated surface for increased flow)
• Composition: refined pulp and pure cotton linters with nearly 100% alpha-cellulose
• Ash content: less than 0.06%
• Grade: Grade 04 (very fast, low-ash hardened)

Advantages:

• Very fast flow rate from creped/pleated construction reduces filtration time for coarse or voluminous precipitates.
• Low ash content supports analytical and gravimetric procedures by minimizing residue on ignition.
• High alpha‑cellulose content and enhanced mechanical strength provide reliable handling and wet strength during vacuum or gravity filtrations.
• Broad applicability across qualitative analysis, water/soil testing, liquid clarification and air monitoring due to hardened low‑ash formulation.
