Description

Description générale

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.

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.

Caractéristiques et avantages

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