Slow filtration (195 s, DIN 53137) for good solution clarification.

2–4 µm pore size for efficient retention of fine particles and precipitates.

Binder‑reinforced paper for improved wet strength and safer handling.


The FF.ALQ1 AllFilter reinforced filter paper is a slow quantitative grade based on a very slow qualitative paper, with a binder added to improve wet strength. Its 2–4 µm pore size and 195 s filtration time according to DIN 53137 provide strong retention of fine particles and high clarification. With an ash content below 1%, it is suitable for many sample‑preparation and analytical tasks where mechanical robustness under wet conditions is a priority. Supplied as flat discs from 70 to 150 mm in diameter in packs of 100, it is particularly useful in chemistry, environmental and quality‑control laboratories that require a durable filter.
