Consolidated sterilizers/autoclaves are made in the U.S. with superior craftmanship and are built to last. Purdue University decided to install an ADVPRO Control System Upgrade on their Consolidate SSR-3A sterilizer that was purchased in February of 2006. This unit is 14 years old but with routine maintenance and the quality manufacturing that Consolidated takes pride in it was still in good working order. Upgrading the controller was a cost-effective way of extending the longevity of this autoclave.
