Autoclave 

 
 

 

Dear Doctor: 

Thank you very much for the trust which you have shown by purchasing this autoclave. 

For nearly 50 years now, MELAG — a medium-sized family-owned and -operated busi-
ness — has specialized in the production of sterilization equipment for medical practice.  
During this period, MELAG has succeeded in becoming a leading manufacturer of sterili-
zation equipment. More than 300,000 MELAG units sold throughout the world testify to 
the exceptional quality of our sterilizers. 

As all other MELAG products, this autoclave was manufactured and tested according to 
strict quality criteria. Before placing this unit into operation, please carefully read this User 
Manual. The long-term functional effectiveness and the preservation of the value of your 
autoclave will primarily depend on careful preparation of instruments before sterilization, 
and on proper care of the unit. 

The staff and management of MELAG
