Filter paper, qualitative

Housing MBS. SFCA / CA (Surfactant-free Cellulose Acetate) membrane. For sterile, particle free, ultrapure filtration of small volumes of liquid up to approx. 100 ml. Colour coded and printed for easy membrane and pore size identification. With hydrophilic cellulose acetate membrane for minimum adsorption. Ready-to-use. With female luer-lock inlet, male luer slip outlet.
