Description

General description

A prepleated filter used for many routine analytical applications in different industries (e.g., particle separation from food extracts or filtration of solids from digested environmental samples, e.g., for ICP/AAS analysis). Time-saving Whatman qualitative grades are offered in this convenient form, which gives major advantages over flat circles.

Grade 595 1/2: 4-7 μm (medium fast, thin filter paper)

Very popular, thin filter paper, medium-fast with medium to fine particle retention. Used for many routine analytical applications in different industries (e.g., particle separation from food extracts or filtration of solids from digested environmental samples, eg., for ICP/AAS analysis).

Features and Benefits

• 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.
