Like the magnetite pellets on your magnet and the soloution is transluent but coloured? or its just opaque and pellets aswell?

You might just need a better magnet, I got a 30x30x15mm n52 beast and it will clear the soloution now no worries. You will probably need to do the synthesis again…Read more

Is it 5mg/ml and then 50:1 like speed beads?

Do you guys freeze dry the beads or?

You will oxidize the magnetite with that many wash steps unless the water is fresh as.

My building is a million years old and the ddH2O is always a little acidic, It gets distilled into a massive tank and stands for a while before getting it out of the tap.
Plumbing is probably full of who knows what but I do have a…Read more
