Filtry jakościowe Grade 5
Standardowy filtr oczyszczający doskonały do zawiesin mętnych oraz do analizy wody i gleby.
A standard grade clarifying filter excellent for cloudy suspensions and for water and soil analysis.

These cellulose filters are used in qualitative analytical techniques to determine and identify materials. Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters.

Grade 5: 2.5 µm
The maximum degree of fine particle filtration in the qualitative range. Capable of retaining the fine precipitates encountered in chemical analysis. Slow flow rate. Excellent clarifying filter for cloudy suspensions and for water and soil analysis. Also available prepleated as Grade 5V.
