A standard grade filter for boiler water 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. Twice as fast as Grade 5 with similar fine particle retention. Often specified for boiler water analysis applications.
