Abstract
A method and apparatus for preventing spotting of the undersurface of the evaporation caps of an incubator in a clinical analyzer. It has been discovered that the surprising cause of the problem was electrostatic attraction building up on the caps, due to the use of plastic parts. The solution to that problem is the provision, in a plastic cover plate mounting the incubator housing on its drive spindle, with carbon fibers rather than glass fibers, in an amount sufficient to provide a volume resistivity throughout the plastic of between about 10.sup.5 and about 10.sup.9 ohm-cm, and grounding the housing through the spindle on which it is mounted.
