GVS Filter Paper, Disk, 90mm, Ashless-Very Slow, Grade 42, 100/PK FP090DXS42QANC01

Qualitative ashless filter paper designed for laboratory filtration and qualitative analysis. It provides low-ash, high-purity filtration for clarification and separation of fine particulates, and is intended for applications such as clarification of hard-to-filter liquids, essences, oils and tinctures and for use in Büchner funnels.

Key Features:

• Diameter: 240 mm
• Format: Disc
• Grade: 03 — Medium-slow filtration, thick
• Box quantity: 100 per pack
