Chemical Resistance Conclusion: QuantumFlux ES membranes can withstand the same chemical cleaning procedures as competing membranes. Performance values for all but two cleaners (L212 and P911) fell into the normal ranges established for the control samples... the membrane samples soaked in L212 and P911 actually improved. - Avista Technologies Report October 2010
