HP Agilent 1100 HPLC G1312A Binary Pump
The HP Agilent 1100 G1312A Binary Pump ensures virtually
pulse-free and stable solvent flow, with dual floating pistons in series,
precisely servo-controlled. This design with variable stroke volume allows
pulse-free solvent delivery and efficient mixing. The G1312A’s
inlet-valve is electronically activated and synchronized to piston stroke to eliminate
vapor formation with volatile solvents and requires no maintenance. The
high-speed proportioning valve and preconfigured vacuum degasser of the 1100
Binary Pump allows convenient low-pressure mixing of up to four solvents and
the highest flexibility in solvent choices. This binary pump can be remotely
controlled via chemstation software or by an external G1323 controller. The HP
Agilent G1312A is easy to use, durable, and offers a wide flow range.
All of our equipment is fully tested to perform at factory
specifications before being shipped.
The HP Agilent 1100 HPLC G1312A Binary Pump includes:
- > Leak and Pressure Diagnostic Report
- > Operator's Manual
- > Power Cord
- > Full 180 Day Parts and Labor Warranty
