Transcript SSI Binary Gradient Pump

SSI Binary Gradient Pump
Modular Simplicity
Ideal Gradient Characteristics
Modular design
Small foot print
Easy Maintenance
Compatible with stand alone control & Data
systems
1ml to 5ml/min flow range with 1% resolution
Integrated Binary Gradient Pump
Small footprint
Integrates fluidics
Simple control
Low dead volume
High precision
Easy Maintenance
Modular design
Simple seal changes
Self flush is standard
Pumps are on pull out
drawers
Each pump is
independently
serviceable
Fluid Path Fully Accessible
Easy Set up
– Connect inlet lines
– Connect line to Injector
– Prime pump
200ml Delay
Ez Prime in head PPV
Simple Front Panel Control
Can select and set
– Flow
– Max pressure limit
– Low pressure limit
Allows monitoring
– Pressure
– Flow
Start or stop the pump
EZ Prime
Allows each head to be
primed independently
Can prime head while
other pump is running
High Performance
Dead volume is minimized
0.001ml/min flow resolution
Out gassing effects minimized since mixing is
on high pressure side of pump
Precise digital control of each solvents flow
Use data system interface for control or
keypad controller
