Kısa Bilgi
Whatman™ Grade 2 kalitatif filtre kağıtları, 8 µm partikül tutma kapasitesine sahiptir; bu, Grade 1'e göre biraz daha yüksek tutma kapasitesi ve eşdeğer bir filtrasyon süresi artışı anlamına gelir. Filtreler, ASTM E 2187-09, Bölüm 9.3.1 ve 9.3.2'de ayrıntılı olarak belirtilen prosedüre göre test edilmiştir. Atmosferdeki ve toprak testlerindeki belirli kirleticilerin izlenmesinde kullanılır.

| Whatman™ 1002-110 Grade 2 qualitative filter paper, standard, circle, 110 mm (100/Pk) Whatman™ Grade 2 qualitative filter papers have a particle retention of 8 µm, slightly more retentive than Grade 1, and with an equivalent increase in filtration time. The filters are tested according to the procedure detailed in ASTM E 2187-09, Sections 9.3.1 and 9.3.2. The paper meets both the conditioned (26.1 ± 0.5 g, SD < 0.3 g) and dried (24.7 ± 0.5 g, SD < 0.3 g) weight requirements. - Each lot is guaranteed to meet the ASTM E 2187-09 specifications - Simplifies testing process by removing lot suitability testing - Just condition and use 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 2: 8 µm In addition to general filtration in the 8 µm particle size range, the extra absorbency is beneficial to applications such as holding soil nutrient in plant growth trials and for monitoring specific contaminants in the atmosphere and in soil testing. Also available prepleated as Grade 2V. |
