Precise low-volume aspiration
The difference between plunger areas creates a small effective displacement while preserving useful mechanical travel for repeatable control.

OEM-ready dual-resolution syringe core
Dual Resolution Syringe
Nanoliter precision. Hundreds of microliters of range.
Replace a conventional syringe in a compatible drive and give the channel fine differential metering, high-volume operation, and clean contact-free delivery—without adding a second pump.

One syringe, a wider operating envelope
Replace the conventional syringe. Transform the channel.
The Dual Resolution Syringe fits familiar syringe-drive architectures while changing what the channel can do. Its dual-plunger geometry enables accurate low-volume work without surrendering the larger volume and flow rate needed for dilution, mixing, priming, and complete dispensing.
For multichannel and automated liquid handlers, this can consolidate tasks that would otherwise require separate syringe sizes, extra fluidic hardware, or contact-dependent dispensing techniques.
Dual Resolution operation
Fine displacement and delivery force in the same channel.
The two plungers can work together for small net displacement or independently when the application needs a larger stroke and higher flow.
Large-volume movement and vigorous flow
Operating a plunger independently unlocks the larger displacement and flow rate needed for rapid filling, dilution, mixing, and priming.
Up to 300–340 µL by modelComplete contact-free dispensing
Available flow supports clean release without touching the destination, helping reduce carryover and contact-related variability.
Touchless delivery pathwayModel pathway
Match the syringe to the drive architecture.
DRD configurations support common Cavro- and Hamilton-style syringe drives with model-specific plunger interfaces and operating volumes.

OEM integration example
Five substituted channels. A much larger operating envelope.
In the archived multichannel example, DRS 15/300 units replace conventional syringes directly in existing drives. Each substituted channel gains differential low-volume control, large-volume operation, and contact-free delivery capability.
