Opis

Opis ogólny

A thin paper with great wet strength and a very high flow rate. Frequently used in technical applications such as the filtration of viscous liquids and emulsions (e.g., sweetened juices, spirits and syrups, resin solutions, oils, or plant extracts). Time-saving Whatman qualitative grades are offered in this convenient form, which gives major advantages over flat circles.

Cechy i korzyści

• Savings in time required to quadrant-fold circles to fit conical filter funnels in repetitive or multiple analyses.
• Decreased overall filtration time because of the extra surface area exposed; the normal slow down of filtration speed due to the loading of particulate is postponed.
• Increased total loading capacity as more filter area is available.
• Maintained flow rate due to the reduction in filter paper contact with funnel side and the self-supporting shape of the filter itself.
• The prepleating does not significantly affect any of the technical data, and the same figures may be used for the flat circles.
