Surface sampling using RODAC plates works best under what conditions
a Flat surface with an expected high bacterial count
b Concave surface with an expected low bacterial count
c Flat surface with an expected low bacterial count
d Convex surface with an expected moderate bacterial count
The answer is "d". RODAC plates are designed so that the dish permits the pouring of a raise convex surface of culture medium for the total surface contact of the area man sampled. The plates are used to establish and monitor the effectiveness of cleaning technique with tests anyone done before and after.
