Very slow filtration (140 s, DIN 53137) for high clarification of solutions.
Ash content < 0.01% suited to demanding gravimetric analyses.
Fine pore size ~2–4 µm for efficient retention of fine particles and precipitates.
The FT.ASP1 AllFilter quantitative flat filter paper is intended for applications where very high clarification is required, particularly in gravimetric analysis. Its fine pore structure, around 2–4 µm, and very slow filtration time of 140 s according to DIN 53137 ensure excellent retention of fine particles and precipitates. With an ash content below 0.01%, it is well suited to determinations after ignition. The 84 g/m² basis weight and 0.17 mm thickness provide reliable mechanical strength for both routine and demanding filtrations in chemistry, environmental and quality‑control laboratories.
