The utility model relates to a nanometer tiny particle research field is specifically said to a seal up equipment of isolated superfine tuftlet up for safekeeping. This equipment includes: first process chamber and second process chamber that the adoption isolating valve is cut apart, first process chamber is used for the superfine tuftlet of deposit, the second process chamber lets in CO2 gas, set up a conveying pole on the second process chamber, the conveying pole lets in the second process chamber and can open the isolating valve and lets in to the first process chamber in. The utility model discloses equipment storing up isolates superfine tuftlet, need not the contact, keeps its cleaning. Because dry ice very easily gasifies, so the granule drops on similar suspension on the dry ice.
