WHATMAN 0.7um GD/X針頭濾器6890-1307
GD/X™專為高顆粒含量的樣品而設(shè)計(jì)，無色聚丙烯外殼，預(yù)濾層由GMF Whatman 150(密度按級(jí)劃分)和GF/F玻璃微纖維介質(zhì)組成，預(yù)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(jí)劃分)和GF/F玻璃微纖維組成的*預(yù)濾層
- 即使是難過濾的該樣品，濾器大幅減少了進(jìn)行單獨(dú)的預(yù)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(chuàng)新的、梯度密度的GMF 150介質(zhì)的zui上層為粗糙網(wǎng)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(yù)濾層下面是終濾膜。GD/X結(jié)構(gòu)提供了非常好的負(fù)載力并有很好的流速，避免產(chǎn)生像單層膜經(jīng)常發(fā)生的高反壓情況。
