A n ISCO Model 1440 high performance liquid chromatograph can give you separations and operating convenience identical to other instruments costing twice as much. Ask anyone else to quote on a chromatograph with these ISCO Model 1440 specifications: • totally pulseless, noiseless, syringe pump • 6 port sample injection valve • high performance multi-wavelength UV photometer with 10cm recorder • fast washout and solvent change. These features are all available elsewhere - but only ISCO can provide them for $5275. And for under $11,000, ISCO can set you up with a two pump system which produces gradients by multilinear programming, a detector which can monitor two wavelengths at once, a 1 0 " recorder, a fraction collector, a digital pressure monitor/controller, and 2 packed columns.
