Testimonial from Vice President, Analytical Development and Manufacturing

"I received the cart yesterday, thanks for the fast delivery! It feels sturdy. I sat on it. It does not bounce. It is also easy to clean and wipe or wash down."

Testimonial from Chemical Engineer

"Thanks again for reacting so quickly and meeting me halfway with the element. We will be able to get installed and have things keep moving overnight with the night crew. The little things like this are always greatly appreciated when working with Liquidyne."

Testimonial from VP Antibody Manufacturing

“This pump cut our processing time from 3 days to 1 shift. I’m not giving this pump back. You will have to come and get it if you want it... and that won’t likely happen.”
