Sartorius, 139H6--47----ACR, Cellulose Nitrate (CN) Membrane Filter

Single packed or dispenser-ready sterile membranes can be used for colony counting, particle testing, microscopy and sterility testing. The membrane filters are made of cellulose nitrate (cellulose mixed ester), cellulose acetate or regenerated cellulose. Choose between gridded or non-gridded single packed sterile membranes, either with or without hydrophobic edge.

Cellulose nitrate, type 139, 0.45µm HIGH FLOW, white|green, 47 mm, 1,000 membranes per box
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.
