描述

一般說明

Time-saving Whatman qualitative grades are offered in folded (prepleated) form, which gives major advantages over flat circles:

• 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

Grade 114V: 25 μm (fast, smooth filter paper)
Strong filter with very fast flow rate. Ideal for coarse particles and gelantanious precipitates. Smooth surface.

特點和優勢

• Nominal particle retention rating of 25 µm
• Fast filtration (Herzberg 38 s)
• Chemically stable resin provides increased wet-strength
• Fluted (pre-pleated) filter sheet for ease-of-use and compatibility with conical funnels
• Smooth filter surface for efficient recovery of precipitates
