It´s our goal  to fulfill our customers expectations  


M.E.L. consulting, sales & service for UHV - applications,  

process & tool development (PTD) for chemical treatments of semiconductor-, MEMS/MST- and photovoltaic structures 


M.E.L offers a wide range of UHV-comnponents like CF-, KF-,ISO-components( flanges, fittings valves , feedtroughs etc. pp.)

This is to support our customer with knowledge,experience and service in HV-. and UHV applications. 

Manipulators are also offered by M.E.L. These manipulators are well known in the market and appreciated by our customer due to the reliability and ruggedness of these prodcuts.  

Other products for HV-and UHV applications are surface analysis systems like scanning-tunneling-microscopes and Kelvin Probes. These offers include the technical support at any time the customer needs it.


Another part of our business is to offer process - and tool - developing of chemical treatments for customer in the semiconductor-, MEMS/MST- and photovoltaic market.


 MEL developed and owns international patents and pending patents for methods and tools since M.E.L. started his business. M.E.L. knows about the importance of innovations and intents to improve  further progresses of these  innovations
