Embodiments of the present invention are directed to storage systems for milk bags. One aspect of the present invention leverages capability of a just-in-time-instrumentation monitoring component to receive a code fix during execution of applications and insert code fixes into applications. The compositions of this invention are reworkable when subjected to appropriate conditions. By controlling the distribution of the processor IPinformation, while still allowing for convenient access, the system and method enable many users to customize the processor IPinformation for a variety of applications, with license condition being granted to the user to manufacture the customized units. Methods of using the foregoing to prepare conjugates with target molecules are also disclosed. Wherein, the first lighting unit emits invisible light, the second lighting unit emits visible light, the first and the second lighting units align with the through hole, and the wireless remote control device is capable of receiving light emitted from the first lighting unit.
