PrimeLine™ Pumps

The ASI HPLC pump is designed with the chromatographer in mind. It can be used as a reliable low cost isocratic pump or integrated into a gradient HPLC System. In either case, the pump incorporates several key features which make it truly one of a kind in the world of HPLC Pumps.

ASI HPLC Pump Features:

Self-Priming

The pump will prime itself with any solvent and at any flow rate. Turn on the pump and open the purge valve, the pump will prime itself even from a completely dry start. You will never need to use syringes to prime it.

Patented Floating Pump Seal

The seal actually floats so that it is always perfectly aligned with the piston. Our tests have proved that the average life with this new patented design is more than 5,000 hours of continuous operation at 6,000 PSI and 10 mL/min. with pure water.

Micro, Analytical, Semi-Prep, and Prep Pump Heads

Intuitive Software Control

The control is designed with dedicated keys that allow even a novice to turn on the pump and create methods. An easy to read 4-line x 20-character LCD display allows the user to monitor several pump parameters from the same screen. The model 501 can be controlled from its own keypad or from a Model 500 gradient controller. When configured as a gradient HPLC system users can program and store up to 60 methods with 20 lines each. Methods may be linked or run independently.

Solvent Compressibility Compensation

The user may select from several different solvents from the on board library. The control automatically compensates for compressibility of the selected solvent.

Easy Maintenance

All user serviceable components are easily accessed from the front panel. Once the head assembly is removed, the pistons and seals can be replaced quickly and easily without the use of tools.

Pressure Sensor

Bonded strain gage with flow through design and digital output

Prime/Purge Assembly

Allows for quick and easy solvent change
