说明

一般說明

Filter papers are manufactured primarily for non-critical industrial laboratory filtration applications requiring inexpensive filters of consistent performance.

Grade 202 provides medium filtration speed of coarse particles. The surface is creped, hence has a greater effective filtration area than smooth surfaced filter papers of the same diameter.

Note; These papers should not be used for kjeldahl nitrogen analysis.

Whatman^® filter paper 202, is widely used in industrial laboratories and student laboratories for routine filtration. The filter is wet strengthened with a small amount of chemically stable resin to extend the life of the filter and improve handling. Normal qualitative applications will not introduce any significant impurities into the filtrate.

特點和優勢

• Filters coarse particles
• Medium filtration speed
• Creped for increased efficiency and filter-life compared to smooth filter papers of the same diameter.
