Key Features & Capabilities

Continuous, Pulse-Free Flow

Alternating dual-syringe operation maintains uninterrupted dispensing — one fills while the other delivers.

Precise Reagent Dosing

Stepper-motor-driven syringes provide accurate addition control and pH maintenance for sensitive reactions.

Wide Flow Rate Range

Configurable from 0.1 mL/min to 12 mL/min depending on syringe size and operating mode.

Multi-Valve Reactor Support

Each reactor block can route through multiple valves, enabling flexible fluid paths and parallel processing.

Optimised Cleaning Workflow

A guided, low-solvent cleaning routine reduces consumable use and minimises system downtime.

Industrial Connectivity

Ethernet and RS-485 interfaces integrate cleanly with external controllers and lab automation stacks.
