Filtry jakościowe fałdowane Grade 5V
Filtr fałdowany do analiz jakościowych, przeznaczony do sączenia roztworów o drobnych cząstkach. Zatrzymuje cząsteczki o wielkości do 2,5 µm.
Whatman™ Grade 5V fine particle filter retains particles as small as 2.5 µm for qualitative analysis. This cellulose filter paper is fluted for ease-of-use.

• Has highest nominal particle retention efficiency of fine particles in Whatman™ qualitative cellulose paper range
• Slow filtration speed (Herzberg speed of 1420 s)
• Fluted (pre-pleated) to facilitate use with conical filter funnels
• Fluted filter paper design decreases filtration time and increases loading capacity

The Whatman™ filter paper range offers a variety of wet-strengthened and standard filter grades, so you can find a cellulose filter paper suitable to your qualitative analysis application.

Grade 5V fluted filter paper for qualitative analysis
The presence of fine particles in a solution can result in cloudy suspensions. A fluted fine particle filter is beneficial for qualitative analysis when used as a lab water filter or as a soil analysis filter.
