This invention is in the field of chemical restructuring of pharmaceutical agents known to cause tissue toxicity as a side effect, by producing their orotate salts. An absorber may have a gas inlet for receiving the flue gas from the heat exchanger, an inlet for receiving a desiccant solution and a media receiving the desiccant solution for providing surface area contact between the flue gas and the desiccant solution A dual cooler may include a first side through which a heat exchanging fluid and the desiccant solution may be directed for cooling. The reticle-carrying container 11 is provided with two sets of kinematic pin grooves 61 for positioning and fastening the reticle-carrying container 11, which are turned 180 degrees from each other on the outer surface of the door 14.
