For precisionfluiddelivery one push is better than a thousand shoves When you need exacting flow control, an Isco syringe pump beats reciprocating pumps cold. There are no check valves to cause flow noise, poor precision at low flow rates, failure at high viscosities. You'll get pulsefree flow throughout wide operating ranges: less than one μΐ/min to 200 ml/min; 0 to 10,000 psi! And programmable flow or pressure - constant or ramping - offers new experimental opportunities. These unique syringe pumps are ideal for demanding jobs such as precision reagent addition, reactant In these pressure recordings at 0.2 ml/min and 3,000 psi, the dual piston HPLC recip feeding, and special LC and rocating pump has over 50 psi pulsation supercritical fluid techniques. while the Isco syringe pump has none.

ENERGY&FUELS AN AMERICAN CHEMICAL SOCIETY JOURNAL
Where Yiou Can Learn More About What's New in the Chemistry of Non-Nuclear Energy Sources Each bimonthly issue brings you reports on the latest research on nonnuclear energy sources: petroleum, coal, shale oil, tar sands, biomass, synfuels, C, chemistry, organic geochemistry, applied catalysis, and combustion. Under the leadership of Editor John W. Larsen of Ixhigh University and Associate Editor Michael T. Klein of the University of Delaware, ENERGY & FUELS keeps you current on the latest news in the transformation, utilization, formation, and produc tion of fossil fuels. Plus, in each issue you'll find thought-provoking communications, book reviews, and guest feature essays by major figures in the field on non-nuclear fuels.
