WHATMAN 6874-2502 25MM 0.2UM PTFE GD/X多層針頭濾器針式過濾器
WHATMAN 6874-2502 25MM
0.2UM PTFE GD/X多層針頭濾器實物照GD/X?專為高粒子含量的樣品而設計，無色聚丙烯外殼，預濾層由GMF
150（密度梯度）和GF/F玻璃微纖維介質組成，預濾層消除了樣品污染物，即使是難于過濾的樣品也有較小的操作壓力。GD/X針頭式濾器的過濾量是普通針頭式濾器的3-7倍。
GMF 150和GF/F由100%硼硅酸鹽玻璃微纖維制成，創新的、梯度密度的GMF
150介質的zui上層為粗糙網格狀，而底部光滑，可保留zui小1.0μm的顆粒。GF/F濾層可保留zui小0.7μm顆粒，預濾層下面是終濾膜。
GD/X具有更大負載量及更快的速度，而不會像常規濾器過濾阻塞時產生反壓。
特征
25 mm GD/X
·濾器直徑有13和25mm兩種
·13mm濾器可過濾zui多10ml樣品，25mm的可過濾10ml以上樣品（可過濾的樣品量還依賴于待濾樣品特征）
·有無菌包裝
·無色聚丙烯外殼
·由Whatman GMF 150（密度梯度）和GF/F玻璃微纖維組成的*預濾層
優點
·去除樣品污染物
·即使是很難過濾的樣品，也不需要很大操作壓力
·是普通濾器過濾量的3-7倍
應用
GD/X針頭式濾器為高顆粒含量樣品的過濾提供*方案
·溶解度測試
·含量均一性
·濃度分析
·常規樣品準備
·食品分析
·環境樣品
·混合物分析
