Too general. Let us know moe information? You asking how to make sample? Of what? What for?

Salma Salman

i just ask about the basic steps for prepration and sepration of bionanomaterials, i don't have definite sample

If so I can only recommend http://www.sonics.com/lp-vibra.htm as tools for separation. Cheers!
