Push/pull syringe pump. Accomodates two syringes for infusion and two syringes for withdrawal. This model supports infusion and withdrawal simultaneously at user defined flow rates and with selectable target volumes to control the total volume pumped. It also supports infuse only, withdraw only, infuse/withdraw/ withdraw/infuse and continuous mode. user defined flow rates with selectable target volumes.

The Legato 270 Syringe Pump has an optimized user configurable syringe mechanism designed to deliver a full volume in infuse and withdraw modes whether using small or large syringes. The reconfigurable mechanism allows the user to change the syringe clamping mechanism to hold from 0.5 ul up to 140 ml syringes. Two removable pins adjust the syringe mechanism to allow full stoke of the larger syringes. 

The Legato 270 features a continuous push and pull pump. When used with check valves, the unit will draw fluid from a reservoir while the opposite side is dispensing fluid and after the user selected volume is dispensed, the pump will automatically switch through the check valves and refill the empty syringes while dispensing from the other side. This will continuously dispense as long as there is fluid in the reservoir. The Legato 270 is one of a family of Legato products featuring a touch screen interface and an easy to view display. The TFT color display presents all the pump operating parameters in an easy to view run screen eliminating incorrect pump configuration. Flow performance is optimized with a small step angle stepping motor that drives a precision lead screw. Accuracy is ±0.35% and has 0.05% reproducibility. The Legato family of products are fully RoHS compliant and offer ETL certifications including CSA, UL and CE Mark. KD Scientific designs,  manufactures and sells a range of quality fluidics equipment used by research laboratory markets worldwide. KD Scientific syringe pumps are an economical solution to delivering precise and smooth flow in research, pilot plants and production applications. They are recognized worldwide for quality, accuracy and reliability. A broad line of syringe pumps are offered: from a simple one syringe infuse only, to a programmable multi-syringe infuse/withdrawal pump.

Legato 200
LEGATO INHERITS KD SCIENTIFIC'S LEGENDARY RELIABILITY
Our experience in pumps and fluidics was used to create the Legato 200 Series. Over the years, customers had asked to display more information simultaneously and make it easier to configure and run complicated multi-step programs. The high resolution touch screen interface offers unparalleled ease of use. Today’s demanding applications require better flow performance and repeatability down to 1 nl/hr. Legato offers 0.35% accuracy and 0.5% repeatability.
DESIGNED TO MEET TODAY’S CHALLENGES
In today’s economic environment, multiple users with different experiments are using the same pump. The next generation of pump had to meet this demand to store and recall multiple programs. The pumps role in the experiment now changes more readily with multiple users and multiple tests being done using a single pump.
ENGINEERED TO MEET GLOBAL REGULATORY COMPLIANCE
Worldwide use of our pumps and changing regulatory compliance meant designing the pump to meet RoHS and WEEE, CE, UL, CSA, and CB schemes. The Legato has lead free boards and is designed to the latest safety and EMI/RFI standards.
