The removal of endotoxin is one of the most difficult downstream processes during protein purification.
Our filter media has been independently tested and found to reduce Endotoxin levels to <0.05EU/mL under laboratory conditions, and actual tests on an Endoscope Washer Disinfector artificially spiked with 196ml of Endotoxin into a 120L tank resulted in ‘None Detected’ cfu/100ml post filtration.
Our Endotoxin removal filters’ composite filter media combining extremely fine filaments of borosilicate glass with Nano Alumina fibres to produce a non-woven material with a very high positive zeta potential of >50mV, which is not discharged by contact with water or alcohol.
The combination of conventional mechanical entrapment by the glass fibre media with electrostatic attraction of the Nano Alumina fibres makes these filters particularly suitable for the removal of negatively charged contaminants such as endotoxins, whilst retaining the traditional high flow with low pressure drop characteristics associated with glass fibre media.
As the filtration efficiency relies largely on electrostatic attraction by positively charged fibres in a relatively open structure, the flow characteristics of our filters are much better than would be expected from a traditional membrane offering similar performance. Flow rates are high, clean pressure drops low, and the dirt holding capacity of the pleat pack is significantly higher than seen in comparable products.
