Hey Guys!! I have been working on gold(3-5 nm) colloids. Now i need to get the precipitates of the same, so thinking about purchasing some membrane filters. But i'm not sure about what type of filter would actually give me high yield. Also i have read that certain filter assemblies and vacuum pumps are required with membrane filters. if anyone can please throw light...
