The present disclosure provides an apparatus including a first chamber containing an eye-mountable device. The apparatus may also include a second chamber containing an aqueous solution. The apparatus may also include a membrane positioned between the first chamber and the second chamber. The membrane may be configured to rupture based on application of a force to the apparatus. The ruptured membrane may allow the aqueous solution to engage with the eye-mountable device. The apparatus may also include a lid to seal one or more of the first chamber and the second chamber.
