crystalloid
[kris´tah-loid]1. resembling a crystal.
2. a substance whose particles are smaller than those of a colloid, form a true solution, and are therefore capable of passing through a semipermeable membrane, as in dialysis. The physical opposite of a crystalloid is a colloid, which does not dissolve and does not form true solutions.
crys·tal·loid
(kris'tăl-oyd),1. Resembling a crystal, or being such.
2. A body that in solution can pass through a semipermeable membrane, as distinguished from a colloid, which cannot do so.
