Whatman 6900-2502 針頭式過濾器

Whatman 6900-2502 針頭式過濾器

  一個獨特的，內置的前置過濾器的過濾器

   用Whatman 25毫米GD / X針頭式過濾器的設計，以方便手動過濾難以過濾樣品大于10毫升

   用Whatman 25毫米GD / X針頭式過濾器包含一個唯一的Whatman多級GMF 150（10:1微米）級和GF / F

（0.7微米）的預過濾器的預過濾棧。針頭式過濾器采用聚丙烯住房。多級GMF 150是兩個于一體的玻璃微纖維過

濾器的組合。從100％的硼硅酸鹽玻璃制造，它是一個組合的粗層的頂部上，嚙合用細層以下。級GF / F濾膜將保

留降低到0.7微米的細顆粒。這些預過濾器，與現有的設備內的滯留空間，允許您篩選前，即使是最困難的樣品也

有較小的力比以往任何時候都可能。未受保護的膜的容量相比，過濾的樣品的體積可以增加三至七倍。

    A unique, built-in prefilter aids in filtering even the most difficult samples

    Whatman 25-mm GD/X Syringe Filters are designed to facilitate manual filtration of hard-to-filter samples greater than 10 mL

    Whatman 25-mm GD/X Syringe Filters contain a unique prefiltration stack of Whatman Multigrade GMF 150 (10:1 μm) and Grade GF/F (0.7 μm) prefilters. Syringe filters feature a polypropylene housing. Multigrade GMF 150 is a combination of two glass microfiber filters in one. Manufactured from 100% borosilicate glass, it is a combination of a coarse layer on top, meshed with a fine layer below.

   The Grade GF/F filter will retain fine particles down to 0.7 μm. These prefilters, combined with the available retentate space within the device, allow you to filter even the most difficult samples with less hand force than ever before possible. Compared to the capacity of an unprotected membrane, the volume of sample filtered can be three to seven times greater. Dual magnets in funnel bottom and support base make filter changing quick and easy.
