WHATMAN硝酸纖維素過濾膜0.2um孔徑25mm直徑7182-002
推薦用于大多數(shù)日常應(yīng)用,這種膜是在嚴(yán)格控制條件下生產(chǎn)。Whatman硝酸纖維素膜確保了非常窄的孔徑分布和極低萃取溶出水平,且具有*的生物相容性,這些都可以讓zui終用戶受益。1975年,Edwin Southern運用Whatman硝酸纖維素膜發(fā)明了舉世聞名的Southern Blotting方法而影響至今。濾膜可以在不失完整的情況下在121攝氏度下進(jìn)行正常消毒。硝酸纖維素膜有圓片、方片和卷等不同規(guī)格。過多的收縮在高壓蒸汽滅菌過程中會產(chǎn)生問題,也經(jīng)常會在高壓蒸汽滅菌后在濾器中發(fā)生斷裂。過多收縮還可能導(dǎo)致流速降低和整個過濾量的減少。Whatman濾膜在高壓蒸汽滅菌過程中展現(xiàn)出非常低的收縮量。
