An apparatus is provided. The apparatus may include one or more of a container, a first magnet assembly, and a second magnet assembly. The container includes an open top and is configured to hold a liquid chemical solution. The first magnet assembly includes a first magnet having a first polarity and a cover, coupled to the first magnet. The cover is configured to be movable between an open and a closed position and limit evaporation of the solution when the cover is in the closed position. The second magnet assembly includes a second magnet having a second polarity. In response to a command, the second magnet assembly is configured to move the cover to the open position without direct contact to the first magnet assembly in response to a command.
