The use of ultrafiltration membranes for the concentration and purification of inorganic and organic macromolecules from environmental samples is required for various analytical methods. Filter devices with ultrafiltration membranes can also be used for the concentration of targets such as inorganic nanoparticle polymers, heavy metal aggregates nanocrystals. Although performing sample concentration and buffer exchange using an ultrafiltration device is relatively simple, some tricks of the trade can improve your recovery or speed up your workflow considerably. Use this guide for proteins, viruses, DNA, polymers, nanoparticles, exosomes, etc. to find the right device and method for your chemical processes.
