Membranas para filtrar fase móvil. SCHARLAU. Ésteres mezclados con celulosa. Material: CEM. Ø (mm): 47. Tamaño de poro (µm): 0,22. Estéril: No. Cuadriculado: No. Color: Blanco.
Scharlau's filtration line has been expanded with newly added filtration membranes for mobile phase filtration. Nylon membranes and Nitrocellulose Mixed Ester membranes of the highest quality are available. rr- We recommend using nylon membranes as the standard material for filtering eluents due to their chemical compatibility. As nylon is hydrophilic in nature, these membranes are appropriate for filtering aqueous solutions and for most of the organic solvents used in HPLC. A nylon membrane has a uniform pore size, consistent flows and a very low level of extractables. rIt can be exposed to up to 180 °C without damage and has a pH range from 3 to 12.rr- Mixed ester membranes are composed of a mixture of inert cellulose nitrate and cellulose acetate polymers. The uniform microporous structure of these filters provides the fastest flow rates and highest throughputs available in a membrane filter. Their hydrophilic nature makes them ideal for filtering aqueous solutions, including buffers. These filters are autoclavable at 121 °C (250 °F) for 20 minutes. The pH range is from 4 to 10.
