This is a Midmark M7 Speedclave Autoclave. We don't have the original factory box but the autoclave has never been used except for our in-house testing to insure factory spec condition.  We purchased this machine from a technical college and they never put them in service. It is complete with rack and three trays. Perfect like new condition. 

The Ritter by Midmark M7 Autoclave is bigger, faster and very efficient. In fact, the speedy M7 Autoclave is the best choice for anyone needing  a small economical tabletop autoclave. Great for the start up practice or tattoo parlor, dental office or busy medical clinic.
