WHATMAN非滅菌GD/X針頭濾器13mm直徑0.7um孔徑6890-1307
GD/X™專為高顆粒含量的樣品而設計，無色聚丙烯外殼，預濾層由GMF Whatman 150(密度按級劃分)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。
13 mm濾器可過濾zui多10 ml樣品，25 mm濾器可過濾10 ml以上樣品(可過濾的樣品量還依賴于待濾樣品特征)
由Whatman GMF 150(密度按級劃分)和GF/F玻璃微纖維組成的特有預濾層
即使是難過濾的該樣品，濾器大幅減少了進行單獨的預過濾步驟的需求
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
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1.0 μm的顆粒。GF/F濾層可保留zui小0.7 μm顆粒，預濾層下面是終濾膜。GD/X結構提供了非常好的負載力并有很好的流速，避免產生像單層膜經常發生的高反壓情況。
