How to get a headstart on new projects.
GT-01 Microprocessor-based Automatic Titrator has the capability of storing up to 15 titration conditions in memory to expedite processing. Titrations can be done in as little as 6 min. An eight-digit LED display reads out cumulative titrant volume, set value, and calculation results. Detected signals are shown on a separate five-digit display. COSA Instrument Corp. 402
There's a lot of i n f o r m a t i o n scattered a r o u n d the w o r l d that can help y o u , if o n l y you can f i n d it. That's the j o b for Lockheed's Dialog, the world's leading o n l i n e i n f o r m a t i o n retrieval system. This c o m p u t e r i z e d sleuth puts you in instant t o u c h w i t h more than 130 databases and provides abstracts of journal articles, c o n ference papers, research reports, patents and news stories — and all of this i n f o r m a t i o n goes back 15 years. Dialog covers v i r t u a l l y every f i e l d , f r o m alkaloids to polymers to zinc. A l l you need to use Dialog is a standard c o m p u t e r terminal and a telephone. Your library probably subscribes to Dialog. Involved in some phase of a new project? Better get involved first w i t h Dialog. It can save you t i m e , m o n e y and e f f o r t — a n d lots of each. For more information, contact Dialog Information Services, Dept. 25, 3460 Hillview Ave., Palo Alto, CA 94304.

Surfactant Electrode Anionic Surfactant Electrode is dedicated to the potentiometric titration of anionic materials in detergents. Surfactants such as detergent range alkylbenzenesulfonates, alcohol sulfates, and alcohol ether sulfates can be analyzed. Based on ASTM method D 4251-83, the potentiometric method eliminates the use of chloroform in assays and simplifies procedures. HNU Systems, Inc.

Fluorescence Spectrophotometer Model MPF-66 provides fluorescence, luminescence, and polarization measurements. It uses the Perkin-Elmer 7500 professional computer and a library of Computer-Aided Chemistry software programs. It includes an optical module that provides excellent resolution and sensitivity, a large and easily accessible sample compartment, and a variety of sample-handling accessories. Perkin-Elmer 415
Asbestos Monitor 3000 Series Model FAM monitors concentrations of asbestos and other airborne fibers. It is designed for industrial applications in the most severe environments, including short-term or continuous monitoring in mines, quarries, and milling and manufacturing operations. Fiber concentrations, ranging from 0.0001 to 30 fibers/cm 3 , are read from a direct digital display. GCA Corp.

Thermomechanical Analyzer TMA 790 is designed to measure dimensional changes as a function of temperature under conditions of compression, tension, or zero load. It can also be used to measure coefficients of expansion over a wide temperature range. An optional fiber attachment can be used to perform these tests on filament material.

Spectrophotometer
C 0 2 Monitor
Sigma ZWS-11 Dual Wavelength Spectrophotometer was developed for difficult-to-measure physiological samples. The fiber optics design provides the flexibility and sensitivity needed to optically monitor oxygen uptake in whole, perfused organs, to measure enzyme kinetics, to follow stopped-flow reaction, or to record difference spectra of turbid suspensions. Varex 418
Riken RI-550A is a direct-reading, single-gas, portable, nondispersive IR gas analyzer for the continuous monitoring of C 0 2 . It is available in dual range combinations from 0- 1 / 2 % full scale, detecting as low as 50 ppm, up to 0 - 1 0 0 % . It can be calibrated by means of an internal disposable calibration gas canister located inside the unit. CEA Instruments, Inc. 417
