Key Benefits
- Industry-leading accuracy — ±0.35% flow accuracy with ±0.05% reproducibility across the full syringe range
- Widest flow range in class — 3.06 pl/min to 215.8 ml/min in a single instrument — from nanoscale injection to bulk fluid transfer
- Universal syringe compatibility — any brand syringe from 0.5 µl to 140 ml; built-in database eliminates manual diameter entry
- Programmable multi-step protocols — Legato 210P: 40 programs × 20 steps for fully automated multi-phase delivery without manual intervention
Overview
The Legato 210 is a full-featured dual-syringe pump built for precision fluid delivery in research laboratory environments. A 4.3-inch WQVGA TFT colour touchscreen and intuitive interface give access to five operating modes: infuse-only, withdraw-only, infuse/withdraw, withdraw/infuse, and continuous. Advanced 1.8° stepper motor technology with 1/16 microstepping (6,400 microsteps per revolution) delivers smooth, pulse-free flow across a flow range spanning picoliter-per-minute precision to bulk transfer rates above 200 ml/min.
The Legato 210P variant adds fully programmable multi-step operation — up to 40 stored programs of 20 steps each (800 total steps) — enabling complex multi-phase delivery sequences without manual intervention. A 75 lb (34 kg) linear force rating handles large syringes and viscous fluids, and the built-in syringe database eliminates manual diameter entry for all major syringe brands from 0.5 µl to 140 ml.
Connectivity covers RS485, USB Type B, and I/O & TTL (15-pin) interfaces for integration with laboratory automation and data acquisition systems. An analog control variant (Legato 210AC) accepts 0–10 VDC for external sensor-driven flow control. Universal 100–240 VAC power supply and CE, UL, CSA, and RoHS certification make the Legato 210 ready for Australian laboratory use without modification.

Frequently Asked Questions
What is the difference between the Legato 210 and Legato 210P?
The Legato 210P adds programmable multi-step operation: up to 40 stored programs of 20 steps each (800 total steps), enabling complex automated delivery sequences. The base Legato 210 supports all standard operating modes but without stored programs. The 210 can be field-upgraded to 210P.
Can the Legato 210 run two syringes at the same time?
Yes. The Legato 210 accepts one or two syringes and can operate both simultaneously — in the same direction or as a push-pull (infuse/withdraw) configuration.
Is the Legato 210 compatible with Australian 240V power?
Yes. The universal 100–240 VAC, 50/60 Hz power supply supports Australian mains voltage without any converter or modification.
What syringes are compatible with the Legato 210?
The Legato 210 accepts any brand of syringe from 0.5 µl to 140 ml. The built-in syringe database includes dimensions for all major manufacturers, eliminating the need to manually enter syringe inner diameters.
Can I control the Legato 210 from a PC?
Yes. RS485, USB Type B, and TTL/I/O interfaces allow integration with laboratory automation systems and data loggers. The optional Adagio software (Part 788000) provides PC-based pump control and sequencing.
