KD Scientific Legato 950 OEM Series Syringe Pump User’s Manual
Publication 5617-012 Rev A
Product Overview
The KD Scientific Legato 950 OEM Series is the next
generation of syringe pumps.
An led light on the front panel makes it easy to see if the
pump is running.
The pumps are versatile and can be interconnected through
the RS485 interface. Legato 950 OEM Series models can
be mixed and matched in the daisy chain offering
maximum flexibility. Up to 99 pumps can be linked together
through the RS485 interface provided each pump is
assigned its own unique pump address.
Flow performance is optimized with a small step angle
stepping motor that drives a precision lead screw and
pusher block. The syringe mechanism is easy to use and
securely holds the syringes for smooth flow performance.
Advanced microstepping techniques are employed to
further reduce the step angle to eliminate flow pulsation.
The accuracy is ±0.5% with 0.05% reproducibility. A
wide dynamic flow range can be programmed into the
pump. Flow rates are selectable with user selected
engineering units from ml, µl, nl pl, and hours, minutes
and seconds.
Up to 30 lbs of linear force is available. This force is user
adjustable to ensure the right force is applied for the
various syringe sizes.
The superior design of the full metal chassis provides
noise isolation and anti-vibration features for increased
reliability.
Easy external connections to a computer or other control
devices are made through USB interface. Simple ASCII
commands make communication with the pump easy. For
direct control of the pump, the user can use the I/O
interface (15pin Dsub). A trigger output and a trigger
input in for external events such as a process parameter is
met. The footswitch input will allow the control of the
pump through an external device. The unit also has an
output for run indication allowing connection to a remote
light.
Single or dual syringes models are available. Complete
flexibility is offered with the user able to use most
manufacturer’s syringes with sizes ranging from 0.5 ul to
60 ml.
