Liquid-Handling Products

DRD's liquid-handling products are based on our unique Differential Displacement/Dual Resolution inventions: 2 pistons give extraordinary precision from diameter difference, and 1 piston gives large volume and speed to deliver contact-free. Our OEM pump modules became an immunochemistry analyzer standard in the 1990s. We now have a full line of end-user and OEM products, liquid & air-filled, manual and automated.
