What Our Clients Are Saying...

“We've been using your UHV products for years. We have grown to trust MPF over all other vendors we've tried. We have never received poor quality product that didn't meet expectations, and your reliable customer service helps us keep track of any order inquiries or product questions. Being a fast-moving company, we live and die by lead times, and MPF consistently delivers on time with extremely competitive lead times when parts are out of stock. Recently we were able to eliminate a troublesome in-house assembly with an off-the-shelf part from MPF, saving us significant amounts of time and money. Overall a very trusted vendor with quality parts and even better employees”.

“We have enjoyed working with MPF on a number of new development projects. We had some challenging requirements and unconventional designs, and MPF worked with us to arrive at a solution that fit our needs”.

“MPF has become our go to for custom brazed sapphire to metal window assemblies. Perfect quality and excellent support.”

"I have had good experiences working with MPF and Duane over the years."

"When I need a viewport or feedthrough MPF always seem to have catalog product in stock. When I need a custom configuration, they are quick to send a quotation communicating all necessary details, and when necessary, a drawing for approval. I'm always confident that the product's quality will be to the highest standards. They're good people at MPF."
