DEFINITION

Classification: 422/263

Including monolithic nonporous body of solute:

(under subclass 261) Apparatus having the solid material in the form of a substantially nonporous body of solute, thereby restricting the liquid-solid contact to the outer surface of the body.

(1) Note. This subclass does not preclude the existence of a flow conducting bore through the solute body to increase the "outer" surface contact area.
