Sartorius 18406--47----ACN RC Membrane Filter, 0.45µ, 47mm, 100Pk

These solvent-resistant, hydrophilic membrane filters are excellently suited for their major application, particle removal from solvents. The 50mm diameter, 0.45µm pore size filter for example, is standardly used to ultraclen and de-gas solvents and mobile phases for HPLC, in combination with the all-glass holder. Regenerated cellulose membrane also feature low non-specific-adsorption.Sterile, gridded membrane filters are widely used for routine microbiological quality control due to the benefits they offer. Whether single-packed or dispenser-ready, the membrane filters are ready-to-use and each filter is individually packed, offering highest security whilst saving preparatory time. Each individual envelope is marked with the filter identification and lot number.

The membrane filters are available in different pore sizes and three different material types. Cellulose nitrate filters (mixed cellulose ester) contain a mixture of cellulose nitrate and cellulose acetate, a material which assures effective retention combined with high flow rates and optimal colony growth. Cellulose acetate combines high flow rates and thermal stability with very low adsorption characteristics. The various filter colors allow the best possible contrast to the colonies for easy and reliable quantification and identification.
