Abstract
A sample frame (30; 81) for preparing a plurality of sample vessels (41, 42), in particular sample tubes, having a plurality of retainers, in each of which a sample vessel (41, 42) is situated, is characterized in that the sample vessels (41, 42) each have a cap (43, 44), which is put over the open end of the sample vessel (41, 42), the cap (41, 42) having a drilled hole (53, 54), through which the interior of the sample vessel (41, 42) is accessible, the sample frame (30; 81) has a removable cover plate (8), whose bottom side faces toward the caps (43, 44) of the sample vessels (41, 42) in the put-on state of the cover plate (8), and the cover plate (8) has an approximately funnel-shaped depression (11, 71) on the top side for each retainer, in whose center a through opening (57) through the cover plate (8) is provided, the through opening (57) aligning with the drilled hole (53, 54) of a cap (43, 44) of a sample vessel (41, 42) retained underneath when the cover plate (8) is put on. The sample frame according to the invention eases the closure of sample vessels, which have a cap with hole, in the context of an automated sample preparation.
