Very fast gravity filtration (10 s) due to pleated design and 15–20 µm porosity.
Increased filtration area from pleating, improving capacity before clogging.
Wide diameter range (70–400 mm) for maximum compatibility with funnels and holders.
What is a qualitative filter paper, pleated, very fast filtration used for?
A Qualitative filter paper, pleated, very fast filtration is designed for high-flow gravity filtration in the laboratory. It is particularly suitable for high-throughput routine analyses, rapid clarification of lightly to moderately loaded solutions, and sample preparation before analysis.
What are the benefits of pleated filter paper?
The pleated format increases the filtration surface area, which improves flow rate and loading capacity before clogging. This makes it faster than a standard flat filter disc in routine gravity filtration applications.
What is the pore size of FL.PSQ1?
This reference has a pore size of 15 to 20 µm. It is suitable for retaining coarse to medium particles, with a low risk of clogging.
What is the filtration speed of this filter paper?
The product page states a very fast filtration speed, with a 10-second filtration time according to DIN 53137. This makes it especially suitable for high-throughput routine analysis.
Is this filter suitable for gravity filtration?
Yes. This reference is specifically intended for gravity filtration. Its pleated design helps maintain high flow in this type of use.
What are the mechanical characteristics of this filter paper?
FL.PSQ1 has a basis weight of 80 g/m², a thickness of 0.21 mm, and a burst resistance greater than 20 kg/cm². These characteristics contribute to good mechanical stability during use.
What diameters are available?
This reference is available in several diameters: 70, 90, 110, 125, 150, 185, 210, 240, 270, 320, and 400 mm. This allows it to fit different funnels and laboratory filtration setups.
What is the packaging format?
The product is sold in packs of 100 pleated filters.
When should this filter paper grade be chosen?
This grade is particularly suitable when very fast gravity filtration is needed for lightly to moderately loaded solutions, with retention of coarse to medium particles and strong flow performance.
Are there cross references for this filter paper?
Yes. AllFilter FL.PSQ1 may be associated with several market references listed in your cross-reference table, including Cytiva/Whatman 4, Prat Dumas 609, Albet 411 / FP604, Filter-Lab 1248, Fioroni 111, Macherey-Nagel 617, Schleicher & Schuell 604, Labbox QLDF, CHMLAB F1004, Sterlitech CFP4, Advantec 1, Munktell 3, Filtrak 288, Hahnemuehle FP604, Ahlstrom-Munksjö 631, and MFS 1288 / 1003.
