I would highly recommend MBR as an OEM partner. They have provided not only great service for us over the years, but our product line performs much better due to their unending quest for quality improvement. 
-Jeff H., New York 

MBR has been very instrumental in our quest to become a serious player in the life science market. They handled everything from production of our reagents all the way down to providing custom labels and very attractive product packaging.
-Dan B., California

MBR's staff of scientists was able to figure out a way to eliminate problems that were surfacing in our assays in very short order. We plan to use their services again very soon!
