Fine aspiration. Powerful delivery.
Differential Pipettors use two closely sized pistons to achieve fine net liquid displacement without relying on a fragile, very narrow piston.
Contact-free dispensing
Deliver by blowoff without touching the receiving site; conventional touch-off is also possible.
Low-volume capability
DRD describes models capable of aspirating down to 0.2 µL.
The hand-held Differential Pipettor
The visible piston design makes it possible to see the paired mechanism while working. Options include adjustable and fixed-volume models.
96-channel semi-automated pipetting
Meet NEPTUNE96
A semi-automated desktop platform combining electronically controlled aspiration and dispense behavior with manually guided head and carriage motion.
96 channels. 384-well access.
DRD describes contact-free dispensing down to 200 nL, with a quadrant locator for 384-well plates. The control software manages piston operation while the user positions the system.
