Fast filtration (27 s, DIN 53137) for routine quantitative analyses.
Ash content < 0.01% suitable for gravimetric determinations.
Pleated format increases filtration area and capacity before clogging.
What is rapid qualitative pleated filter paper used for?
Rapid qualitative pleated filter paper is designed for routine gravity filtration in the laboratory. It is particularly suitable for rapid clarification of lightly to moderately loaded solutions, routine analyses, and production quality control.
What are the benefits of pleated filter paper?
The pleated format increases the available filtration surface area. This helps improve flow rate, increase loading capacity before clogging, and make gravity filtration more efficient in routine use.
What is the pore size of FL.PRQ1?
This reference has a pore size of 12 to 15 µm. It is suitable for retaining coarse to medium particles, offering a good balance between flow rate and clarification level.
What is the filtration speed of this filter paper?
The product page states a rapid filtration speed, with a 20-second filtration time according to DIN 53137. This grade is therefore suitable when high flow is needed in gravity filtration.
Is this filter suitable for gravity filtration?
Yes. This reference is explicitly intended for gravity filtration. Its pleated structure helps maintain good flow while limiting clogging.
What are the mechanical characteristics of this filter paper?
FL.PRQ1 has a basis weight of 88 g/m², a thickness of 0.18 mm, and a burst resistance greater than 20 kg/cm². These characteristics support good mechanical strength during use.
What diameters are available?
This reference is available in 70, 90, 110, 125, 150, 185, 210, 240, 270, 320, and 400 mm diameters. It can therefore fit many standard funnels and filtration supports.
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 especially suitable when rapid gravity filtration is required for lightly to moderately loaded solutions, with retention of coarse to medium particles and efficient routine throughput.
Are there cross references for this filter paper?
Yes. AllFilter FL.PRQ1 may be associated with Cytiva/Whatman 597, according to the cross-reference information available in your database.
