PCTE(Polycarbonate) Membrane Filters, Hydrophobic / PCTE(폴리카보네이트) 멤브레인 필터, 소수성 These extremely strong, hydrophobic (PVP-free), polycarbonate track etch (PCTE) membrane filters minimize extractables and are our lowest non-specific binding membranes; these properties make them ideal for chemotaxis, cell studies, and venting applications. Sterlitech's hydrophobic PCTE membranes are produced from a a two-step, quality-assured, proprietary manufacturing process delivering consistent products with pore uniformity, predictable flow rates, and trusted particle retention levels. A single, integral, microporous polycarbonate film is used to produce the membranes and provide them with their thin, translucent, structure and the glass-like surface characteristics that enable superior particle visibility and easy microscopic analysis. Their pores are absolutely-rated, precisely cylindrical, and narrowly distributed, allowing their surfaces to capture 100% of particles larger than pore sizes. These membranes are also available in hydrophilic, PVP-coated discs for applications involving aqueous and alcoholic samples. Applications •Precisely controlled cylindrical pores for maximum absolute particulate capture •Transparent, smooth flat surface for microscopic work •Lowest, non-specific binding membrane •Narrow pore size distribution •No sloughing or particle shedding, one integral plastic film •Negligible adsorption or absorption •Low extractables
