A locator bed has nests where sample well containing plates are held and positioned for accessing by probes moved by an X-Y-Z positioning system. Each nest includes stop posts at two sides of a rectangular base of a plate, and biasing posts at the opposed two sides. The stop posts and the biasing posts have tapered upper guide portions for guiding a descending plate into position and cylindrical lower portions receiving the base of the plate in a seated position. The stop posts are located on the surface of the locator bed by conical seat portions. The biasing posts are placed over studs fastened to the bed surface, and hoop springs are captured between the studs and the biasing posts.
