Firstly these two kinds of autoclave sterilization machines got their own advantages on heating-up speed and cooling, uniform thermal distribution, and etc. But It mainly depends on the loads packing material and size, if glass ampoule, and size is 1ml, 2ml, 5ml, 10ml, we recommend steam sterilization with advantage of fast heating-up and less cost on utility consumption. However, if the container size over 10ml, then superheated water cascade sterilizer is more appropriate to reduce the broken rate after sterilizing, with advantage of regular heating-up, but it costs more on utility consumption and budget. Customer needs to consider based on own situations and long term operation.
