Elga Labwater Pre-treatment Cart Unit EA. Before these devices can be operated they must be preconditioned. The Elga Labwater Cart provides the necessary conditions for the pre-treatment. The Elga Labwater Cart contains a perforated basket which holds two standard test tube racks side by side leaving plenty of space between the water inlet and the perforated outer surface for the perforations to pass through. To drain the water the lower basket has to be removed and the perforated outer surface replaced. The resulting puddle is then sanded and polished.
