Review on Diameter Lab Supply by Membrane Solutions by Sean Patel

They work great and are very easy to squeeze compared to some other brands although I don't think they used particularly difficult filter materials. Some non-paper micron filters can hit or miss, but all 10 worked smoothly and produced a clear solution with ease. Will buy again if we need pes filters. I see no point in spending twice as much. They were more comfortable to use than some of the cheaper alternatives that can clog and then break with too much pressure. They are always filtered like a hot knife through butter.
