WHATMAN 6874-2502 25MM 0.2UM PTFE GD/X多层针头滤器针式过滤器
WHATMAN 6874-2502 25MM
0.2UM PTFE GD/X多层针头滤器实物照GD/X?专为高粒子含量的样品而设计，无色聚丙烯外壳，预滤层由GMF
150（密度梯度）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。
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1.0μm的颗粒。GF/F滤层可保留zui小0.7μm颗粒，预滤层下面是终滤膜。
GD/X具有更大负载量及更快的速度，而不会像常规滤器过滤阻塞时产生反压。
特征
25 mm GD/X
·滤器直径有13和25mm两种
·13mm滤器可过滤zui多10ml样品，25mm的可过滤10ml以上样品（可过滤的样品量还依赖于待滤样品特征）
·有无菌包装
·无色聚丙烯外壳
·由Whatman GMF 150（密度梯度）和GF/F玻璃微纤维组成的*预滤层
优点
·去除样品污染物
·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
