Waters 717 HPLC Autosampler, 486 Tunable Absorbance Detector & 501 Pump
$8,900*

The Waters 717 Autosampler injects samples into high performance liquid chromatography system. The Waters 717 Autosampler automates sampling by storing up to 96 sampling methods or "steps". Each method controls all injection parameters for a sequence of vials.

The Waters 486 Tunable Absorbance Detector is a single-channel tunable ultraviolet/visible detector designed for high performance liquid chromatography applications. The Waters 486 can operate as a stand-alone unit or with other Waters system modules. The Waters 486 provides a usable light intensity over the wavelength range of 190-600 nm.

The Waters 501 Pump is a high performance pump designed specifically for liquid chromatography applications. You may set flow rates from 0.1 to 9.9 ml/min in increments of 0.1. It automatically monitors compressibility compensation values to maintain accuracy at high pressures.

All above instruments are in good condition and tested at GenTech. They include a SIX (6) MONTH WARRANTY.

SRI Model 203 Single Channel Chromatography Data System* includes PeakSimple Software to run with Windows 95, 98 Me, XP, and Windows NT 4.0, allows acquisition, integration and display of one detector channel from a GC or LC. Includes two independent timebases, two 0-5VDC DACs, two remote start inputs and built-in AC power supply. Also includes 24-bit serially interfaced acquisition hardware, manuals, FREE lifetime software upgrades and TWO (2) YEAR WARRANTY.

**GenTech is a distributor of new SRI instruments Does not include computer - requires Win 95 or newer.

*All prices are in U.S. dollars and do not include shipping, handling and installation. International Cooperating Organizations
