Preparative Chromatography
Pumps
The Prep Pumps have been
specifically designed for Preparative Chromatography
applications. The units provide high flow rates and high
pressure capabilities, with consistent performance to
minimize the potential for column damage.
The pumps deliver a
maximum flow rate of 24 (6000 psi) or 100 mL/min. (3000
psi).
.Standard controls include
RS-232 serial communication port, Run/Stop inputs and
remote frequency & voltage controls. Real-time
pressure monitoring with user selectable upper &
lower pressure limits is standard. All
SSI pumps include a 3-year warranty.
Upgrade to High-pressure Gradient:
The combination of two
Prep 100s gives you the capability to pump 200 mL/min. at
4000 psi. An optional compact stand-alone keypad is used
for convenient high-pressure gradient programming without
the requirement for a computer.
Standard
