New syringe pumps give precision flow atmicrorates Because Isco syringe pumps feature high calibration accuracy and no detectable flow noise or pulsation, they'll outperform any reciprocating pump for high precision at very low flow rates. Use them for operations from microbore liquid chromatography and reaction vessel feeding to rock core flooding. These pumps offer fast pressurization that reduces equilibration time from hours to seconds. Their motorized refill/purge functions can be completed in less than five minutes. An optional serial interface permits external computer control of key p u m p functions. Now there are three versions to choose from, so you don't have to compromise your project conditions. Pressure limits range to 10,000 psi; flow rates from 0.02 μΐ/min to 6.67 ml/min; and cylinder capacities to 500 ml. For more information, call toll free (800)228-4250, or write: Isco, Inc., P.O.
