WHATMAN非灭菌GD/X针头滤器13mm直径0.7um孔径6890-1307
GD/X™专为高颗粒含量的样品而设计，无色聚丙烯外壳，预滤层由GMF Whatman 150(密度按级划分)和GF/F玻璃微纤维介质组成，预滤层消除了样品污染物，即使是难于过滤的样品也有较小的操作压力。GD/X针头式滤器的过滤量是普通针头式滤器的3-7倍。
- 13 mm滤器可过滤zui多10 ml样品，25 mm滤器可过滤10 ml以上样品(可过滤的样品量还依赖于待滤样品特征)
- 由Whatman GMF 150(密度按级划分)和GF/F玻璃微纤维组成的*预滤层
- 即使是难过滤的该样品，滤器大幅减少了进行单独的预过滤步骤的需求
- 即使是很难过滤的样品，也不需要很大操作压力
- 是普通滤器过滤量的3-7倍
GMF 150和GF/F由100%硼硅酸盐玻璃微纤维制成，创新的、梯度密度的GMF 150介质的zui上层为粗糙网格状，而底部光滑，可保留zui小1.0 μm的颗粒。GF/F滤层可保留zui小0.7 μm颗粒，预滤层下面是终滤膜。GD/X结构提供了非常好的负载力并有很好的流速，避免产生像单层膜经常发生的高反压情况。
