標準級玻璃纖維濾膜，不含有粘合劑和其他添加劑，能報保證產品性能穩定和化學穩定性。能夠有效過濾顆粒物，阻力小，高通量，對高濃度顆粒物過濾非常有效，多層纖維結構能有效避免顆粒物帶來的壓力降過快增長。

Ahlstrom 151:

0.7μm Slow Speed 慢速玻璃纖維濾膜

具有極高的捕集效率，收集大于0.7 μm顆粒物. 與其他玻璃纖維相比Ahlstrom 151具有較高的流速和通量，尤其適合于核酸盒生化溶劑過濾。151和 141級高效過濾效果適合于預過濾膜。151級玻纖膜推薦用于EPA 方法1311 中TCLP處理。

Ahlstrom 121:

1.0μm Medium Speed 中速玻璃纖維濾膜

Ahlstrom 111 具有較大的厚度盒較高的濕強度和高通量，適合用于液體澄清和溶劑中細顆粒物的過濾， 液體閃爍計數。Ahlstrom 121 is recommended for the clarifi cation of liquid suspensions loaded with fi ne particulates. Ahlstrom 121 is also used in membrane pre-fi ltration and is also found in quantifi cation of solids, and LSC (Liquid Scintillation Counting) techniques that require high loading capacity.

Ahlstrom 131:

1.0μm Medium Speed中速玻璃纖維濾膜

在眾多環境分析應用，尤其適用于污水過濾率和工業廢水過濾，與111級相比具有更低的速率。適合細胞收集，液體閃爍計數，空氣采樣和污水過濾。This standard grade found in many environmental applications offers slightly more retention than Ahlstrom 111 with slightly lower filtration speed and loading capacity. Ahlstrom 131 is recommended for the collection of suspended solids in potable water and in industrial wastes. In biochemical tests, Ahlstrom 131 is suited for cell harvesting, liquid scintillation counting and the analysis of carbohydrates.

Ahlstrom 161:

1.1μm Medium Speed 中速玻璃纖維濾膜

的細顆粒盒高流速的分析用濾紙。適合細胞收集，液體閃爍計數，空氣采樣和污水過濾。 This popular grade offers finer particle retention and higher flow rate than traditional analytical filter papers. Ahlstrom 161 is used in general laboratory applications, cell harvesting, liquid scintillation counting, and in the monitoring of air and water pollution. Ahlstrom 161 is generally recommended for water pollution monitoring techniques for total suspended solids.

Ahlstrom 169:

1.0μm Fast Speed 快速玻璃纖維濾膜

表面光滑，不含膠黏劑，，能耐500攝氏度高溫，適合于TCLP測試方法，懸浮物測定，空氣污染采樣，揮發性固體測試。 This glass microfi ber grade is a smooth surface, binder-free fi lter with unique high temperature resistance. It offers fi ne particle retention and product stability to over 500 degrees Centigrade. The temperature resistance makes Grade 169 well-suited for TCLP test methods, suspended solids determination, volatile solids testing, air pollution testing, and related EPA and ASTM protocols.

Ahlstrom 111:

1.2μm Fast Speed 快速玻璃纖維濾膜

This grade offers fi ne particle retention with high fi ltration speed and good loading capacity. Ahlstrom 111 is used in general laboratory fi ltration including atmospheric and water pollution monitoring such as intake controls, ozone-level, and water effl uents. Grade 111 is also well suited for fi ltration of water and protein, testing of algae, bacteria cultures and for radioimmunoassay with weak beta emitters. Ahlstrom 111 is also recommended for fi ltering solvents in a high-resolution laboratory.

Ahlstrom 141:

3.1μm Fast Speed快速玻璃纖維濾膜

This grade offers better fi ltration speed and a higher loading capacity than an analytical fi lter paper of similar particle retention. Ahlstrom 141 is particularly recommended for pre-fi ltration of membrane fi lters and is also used in combination with Ahlstrom 121 as a highly effi cient protective and retentive grade density pre-fi lter for membrane fi lters.
