Questions To Ask Before You Buy Your Next HPLC Pump The heart of any HPLC system is the pump; so it pays to get all the facts before you buy. Ask about the pump's reliability. Micromeritics' 7 5 0 pump has an impressive mean time between failure rate of over two years. Ask about solvent delivery precision. The 7 5 0 has the smoothest, most pulse-free delivery available. Ask about serviceability. The 7 5 0 is designed for quick access to all common maintenance areas. Ask if the pump has a primer for fast, easy air removal, or if you have to stop the pump to use syringes and other hardware to restore flow. Ask if the pump has high and low pressure limits. High pressure limits protect against possible system damage.

Low limits help shut the pump down in case of leaks or solvent depletion. The 7 5 0 pump has both. Ask about upgradability. The 7 5 0 can be used without modification for both gradient and isocratic analyses. Micromeritics' 7 5 0 pump can give you all this, plus automation and hard copy printout adaptability to help you meet Good Manufacturing Practice standards. Pumps with less capability have their place, but probably not in your lab. Now, ask for a demonstration with no obligation. Call (404) 4 4 8 - 8 2 8 2 . Or write for additional information to Micromeritics Instrument Corporation, 5 6 8 0 Goshen Springs Road, Norcross, GA 3 0 0 9 3 U.S.A.

This automated isocratic system includes the 750 pump, 725 Autolnjector and 786 variable wavelength detector.
