Abstract
Described is an improved process for fragmenting a biomaterial and isolating and recovering a component thereof. The preferred improved process includes the step of performing the fragmentation by nebulizing a liquid medium containing the biomaterial. A preferred process for fragmenting isolated DNA includes the step of nebulizing a fluid containing the DNA. This preferred process provides randomness superior to prior known DNA fragmentation methods, as well as other important advantages. Improved nebulization devices are also described.

4. A device for nebulizing a liquid, comprising:
-
a base member having internal channels adapted to deliver a liquid sample mist out of an opening in the base member; an upper member removably connected to the base member and defining an internal chamber into which said mist is delivered; a nebulization barrier movably attached to the upper member so as to be positionable to selected locations within said chamber so as to be contacted by the liquid sample mist at varying distances from said opening; and positioning means located externally of said chamber for positioning said nebulization barrier to said selected locations. - View Dependent Claims (5, 6, 7)

8. A device for nebulizing a liquid, comprising:
-
a base member having internal channels adapted to deliver a liquid sample mist out of an opening in the base member; a first upper member removably connected to the base member and defining a first internal chamber; a second upper member removably connected to the base member and housed within said first internal chamber;
said second upper member defining a second internal chamber smaller in volume than said first internal chamber and into which said mist is delivered;
said second upper member also having an opening; anda nebulization barrier attached to the first upper member and positionable through the opening in said second upper member to selected locations within said second internal chamber so as to be contacted by the liquid sample mist at varying distances from the opening in the base member. - View Dependent Claims (9, 10, 11, 12, 13)
