GVS Filter Paper, Disk, 70mm, Glass Fiber, Grade FA, 1.6µm 100/PK FP070DFAFAGLFC01

Low-ash, hardened GVS qualitative filter paper in 150 mm disc format providing medium-slow (thick) filtration for laboratory separations. It is designed for fine particle retention and high loading capacity, with increased wet strength from its extra thickness; it is particularly used for filtering liquids that are hard to clarify — including essences, oils and tinctures — and is suitable for use in Büchner funnels and similar preparative filtration setups.

Key Features:

• Diameter: 150 mm (disc)
• Filtration grade: Grade 03 — Medium-slow filtration (thick)
• Ash content: low ash (≤ 0.06%)
• Sheet construction: hardened/low-ash cellulose with increased thickness (double thickness vs Grade 01)
• Box quantity: 100 per pack
• Primary use: suitable for Büchner funnels and preparative vacuum filtration

Advantages:

• Fine particle retention with excellent loading capacity for clarifying difficult liquids
• Increased wet strength from extra thickness enables handling under vacuum and higher solute loading
• Low ash content minimizes contamination of analytical precipitates
• Well suited for preparative and gravimetric filtration of oils, tinctures and essences
