For less than $ 5 , 5 0 0 , our new 3D™ HPLC System is an amazing breakthrough in LC technology. Only from Perkin-Elmer A complete HPLC System—the Series 100 pump, 7010 injector, a P-E 3x3 C18 cartridge column, R-50 recorder and the new TriDet™ trifunctional detector—all for the amazingly low price of $5,460* The 3D HPLC System is an excellent tool for teaching, quality control, screening—for any laboratory where quality technology is required on a limited budget. 3 detectors in one The central focus of the new 3D HPLC System is the patented** trifunctional TriDet detector. UV, Fluorescence and Ion Conductivity
detection are all built into a single compact unit. For multiple, simultaneous detection, or to have three of the most often used LC detection modes at your fingertips, the flexibility of the 3D H PLC System can't be beat. Even if your only application is Ion Chromatography or if you only require the UVfunction, the3D HPLC System is still a great value. It's very easy to use The 3D HPLC System is a joy to operate. As the workhorse in a quality control lab, the mainstay of a therapeutic drug monitoring lab, or the first LC in a college chemistry lab, the 3D HPLC System sets up easily,
and runs reliably, day after day. For complete information on this highly economical new system, talk to your Perkin-Elmer representative. Or, for literature, please call 1-800-762-4000. * F.O.B. Norwalk, CT, USA ** Patent Pending Perkin-Elmer Corp., Main Ave. (MS-12), Norwalk, CT06856 U.S.A.
