LEGATO 272 PUSH / PULL SYRINGE PUMP
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.
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.
