Whatman 6900-2502 针头式过滤器

Whatman 6900-2502 针头式过滤器

  一个独特的，内置的前置过滤器的过滤器

   用Whatman 25毫米GD / X针头式过滤器的设计，以方便手动过滤难以过滤样品大于10毫升

   用Whatman 25毫米GD / X针头式过滤器包含一个唯一的Whatman多级GMF 150（10:1微米）级和GF / F

（0.7微米）的预过滤器的预过滤栈。针头式过滤器采用聚丙烯住房。多级GMF 150是两个于一体的玻璃微纤维过

滤器的组合。从100％的硼硅酸盐玻璃制造，它是一个组合的粗层的顶部上，啮合用细层以下。级GF / F滤膜将保

留降低到0.7微米的细颗粒。这些预过滤器，与现有的设备内的滞留空间，允许您筛选前，即使是最困难的样品也

有较小的力比以往任何时候都可能。未受保护的膜的容量相比，过滤的样品的体积可以增加三至七倍。

    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.
