Syringe pump delivers full stroke for large syringes

Legato 270 Syringe Pump Available from Dorton Analytical - the new Legato 270 Syringe Pump has an optimised user configurable syringe mechanism designed to uniquely deliver a full volume in infuse and withdraw modes whether using small or large syringes. This 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 when using 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 the latest in the family of Legato products that features a touch screen interface and an easy to view display.   The TFT colour display presents all the pump operating parameters in an easy to view run screen eliminating incorrect pump configuration. Flow performance is optimised 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.

Available from Dorton Analytical - Legato syringe pumps are an economical solution to delivering precise and smooth flow in research, pilot plants and production applications.   They are widely recognised for their quality, accuracy and reliability.   A broad line of syringe pumps are offered: from a simple one syringe infuse only pump, to a programmable multi-syringe infuse/withdrawal pump.
