Pipettor
Program repeatable aspiration and delivery across micro- and milliliter-scale workflows.
Programmable benchtop liquid handling
A versatile Differential Pipettor™, Diluter™, and Dispenser™ built to handle volumes from 100 nanoliters to 1 milliliter—combining fine low-volume control and higher-flow delivery in one programmable system.

Broad range without compromise
The DPDD 1000 is designed for workflows that need more than a single fixed-volume behavior. Its programmable platform supports tiny samples, larger liquid movements, dilution, and controlled dispensing without changing the underlying mechanism.
Differential Displacement™ separates the need for fine resolution from the need for strong flow—making it possible to approach small-volume precision and clean release in the same system.
Three operating pathways
Use DPDD 1000 as a pipettor, diluter, or dispenser, with programmed movement and a handheld probe for practical benchtop operation.
Program repeatable aspiration and delivery across micro- and milliliter-scale workflows.
Combine precise sample handling with controlled diluent delivery in one benchtop system.
Deliver programmed volumes with the flow needed for clean, contact-free release.
Dual-resolution architecture
Two pistons of different diameters can operate together to create a small net displacement or independently to move liquid and air at higher flow. The instrument applies those behaviors across a programmable range.
A practical benchtop workflow
The DPDD 1000 combines an instrument display and controls with a handheld probe, tubing, and source reservoir for flexible day-to-day operation.

Choose the required pipetting, dilution, or dispensing program and target volume.
Use differential piston behavior where small-volume control is the priority.
Apply the system’s higher-flow behavior for complete delivery, including contact-free Blastoff operation.
Evidence across the low-volume range
DRD’s science collection includes comparisons with conventional pipettors, Artel-based nanoliter studies, aspiration-depth analysis, and contact-free delivery experiments.
