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.
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.
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/Pure Assembly
Allows for quick and easy solvent change

The Model 501 is a high performance, compact solvent delivery module that has been designed to compete with the most expensive pump systems on the market in reliability and performance without the high cost. A dual piston design with solvent compressibility feedback assures virtually pulse-free and accurate solvent delivery. The Model 501 has all of the features of the Model 500, but without gradient programming capability. It may be used as an economical stand alone pump for isocratic operation, or in conjunction with a Model 500 for gradient operation.
The Model 501 Solvent Delivery system is a dual piston reciprocating pump. The pump comes configured with one of three pump heads: analytical, semi-prep, or prep. In each case the pumps feature a self-priming pump head, a patented "floating pump seal" design for extended seal wear, and an integral prime/purge assembly for changing solvent quickly. The user interface includes intuitive software control and programmable solvent compressibility compensation.
