An apparatus and method for carrying out and monitoring the progress and properties of multiple reactions is disclosed. By connecting a thermoelectric material to an electrically conductive substrate with the electrically conductive paste of the invention, a suitable electroconductivity is imparted to the connecting portion of the thermoelectric element. The degassing chamber has an opening enabling gas and water vapor drawn out from the fluid, and condensation formed from the water vapor, to flow out as a result of gravitational pull. The safety member further has an engaging pin which is removably engaged with the recess of the activation plate so that when the sliding door is in open position, the activation plate cannot be moved and the hooks are remained in the sliding door. It is adapted for use with existing liquid containers, such as bottles, jerricans, beer kegs, or barrels, and makes pouring an easy task for anyone, and in particular, for children, the elderly, and people with disabilities.
