Hey Everyone The basic surgery disinfection wipes we currently use are 82% ethanol 0.5% Chlorhexidine and costs 70dkk (for 50) AU has an agreement with a company that can deliver another brand, which is only 75% ethanol. (still 0.5% Chlorhexidine) for 10DKK (for 50) Does anyone have a good argument (scientific or otherwise) for why should NOT swap to the cheaper wipes? As far as I remember 70% - 75% is optimal for killing bacteria, and higher concentrations being more for RNA work. https://www.webapoteket.dk/medicare/desinfektion/desinfektionsservietter/dis... https://online.abena.dk/Product/Pdf/1999918634?type=SKI_Forbrug_varedatablad Enjoy your weekend when you get there.
