Abstract: The disclosed techniques include a space filling device to be used with a wet bench in chemical replacement procedures. The space filling device has an overall density that is higher than the chemicals used to purge the wet bench. As such, when embedded into the wet bench, or more specifically, the chemical tank of the wet bench, the space filling device will occupy a portion of the interior volume space. As a result, less purging chemicals are used to fill and bath the wet bench.
