Abstract
A sterile containment welding device includes a self-monitoring heater unit upstream from the space between the tube receiving channels. The wafer is positioned in the unit and mounted for movement through the unit prior to moving through the space. The self-monitoring heater unit comprises a heater which heats the wafer and a temperature sensor for monitoring the temperature created by the self-monitoring heater in a rapidly alternating sequence so that the wafer is heated to a predetermined temperature before being moved into the space and contacting the plastic tube or tubes.
