Abstract
A quick disconnnect connection for a bulk chemical supply container in an automatic refill system for a liquid chemical temperature controller is provided wherein replenishing liquid chemical is automatically supplied from the bulk chemical supply unit to a bubbler ampule in the liquid chemical temperature controller. The quick disconnect connection has shutoff valves that isolate the bulk chemical supply container to prevent depth contamination of the replenishing chemical upon connection and disconnection of the bulk supply chemical container from the automatic refill system.
