Membrane Filters [MF] Mixed cellulose estersMF-MCE The MCE membranes are made with cellulose acetate and cellulose nitrate fibres, they are naturally hydrophilic, mechanically stable and have a high loading capacity. They are suitable for microbiological analysis or for pre-filtration and clarification of samples
[MF] Cellulose acetateMF-CA The CA membranes are produced with pure cellulose acetate which is modified, and have a high filtration efficiency. Naturally hydrophilic, they present a good thermic stability and a weak fixation of proteins. They are suitable for biological, aqueous samples and for filtration of proteins or enzymes.
[MF] Polytetra-fluorethylene MF-PT Naturally hydrophobic, the PTFE membranes are made with polytetra-fluroethylene laminated with a PP layer. They can be used in air and gas filtration or for chemically aggressive or acid for samples. For the filtration of aqueous solutions, you should wet them first with isopropanol
