Cover Glass for Howard Cell
Note: The complete system requires both the cell itself and cover glass. The cell does not come with a cover glass and one must be ordered separately. We recommend ordering one or two extra cover glasses since they do tend to break at the most inconvenient of times and this way there is always going to be one in reserve.
