ΑIΑ-600 automated immunoassay analyzer is designed for the measurement of tumor markers, proteins, and thyroid and other hormones in serum samples. The system is based on enzyme immunoassay technology. Tosoh Medics 401
TLC. ScanDuet TLC radioimaging and analysis system, which consists of two automated scanners directed by a single multitasking computer, loads and reads up to eight 20 X 20 cm plates without operator intervention. Fifty dpm of 3H or I4C can be measured in 10 min. Bioscan 404
Spectrophotometer. Model U-4001 UV-vis-near-IR double-monochroma-tor, double-beam recording spectrophotometer, designed primarily for use with solid samples, features a large sample compartment that allows the analysis of semiconductor wafers, special optics, glass films, and coatings. Hitachi 405
IR. RS-1250 is a modular near-IR recording spectrophotometer with a wavelength range of 750-1700 nm and a resolution of 1.5 nm. The optical module incorporates a scanning digital monochromator, germanium detector, 20 W source, and a sample compartment with 90° and 180° detector ports. Optometries 406
Viscometer. VT501 features a built-in microprocessor for monitoring and display of viscosity, shear rate, temperature, torque, and speed. Applications include the testing of oils, polymer solutions, slurries, paints, inks, lotions, creams, and foods. Haake, Fisons Instruments 407
EPR/ESR. Model 8300 EPR/ESR spectrometer features a Hall-effect probe that provides field regulation of
±4 ppm over the 250-6000 G magnetic field range. The solid-state microwave source is tunable from 9.1 to 9.9 GHz. Micro-Now Instrument Co. 408
Oil analysis. MOA-M multielement oil analyzer, designed primarily for laboratory rather than field applications, incorporates 30 channels and an IBM PS/2 computer. The system is intended for the analysis of used oils, hydraulics, and fuels. Baird 409
LC detector. Model LC-304 fluorescence detector features two holographic grating monochromators and a 2-nm-pathlength flow cell that is external to the unit. The instrument design eliminates the need for dark current correction. Linear Instruments
410
Distillation. Single effect deluxe Os-mostill, which provides 1 Mohm-cm pyrogen-free ultrapure water for a variety of laboratory applications, features fully automatic controls that allow continuous 24-h operation. A resistivity meter is used to monitor final distillate quality. Osmonics 411
FIA/IC. QuikChem automated ion analyzer incorporates both flow injection analysis and ion chromatography. The system can be used to profile environmental samples for basic anions, alkali metals, alkaline earths, and transition metals. Lachat Instruments 412
Oxygen. Model 3160 trace oxygen analyzer features full-scale accuracy of ±2%, four measurement ranges, authorization entry code to prevent tampering, automatic electronic zero, and user-selectable analog or digital outputs. Atmospheric air can be used for calibration. Teledyne Analytical Instruments 413
Software Curve fitting. TableCurve performs one-pass least-squares curve fitting to 221 candidate equations. Equations are ranked by r2 coefficients; the user can examine graphically any equation and can view standard errors, the F-statistic, and prediction/confidence tables. Jandel Scientific 415
Assays. Autoassay is a set of five computer programs designed to record measurements and perform calculations for agar diffusion assays. Included is software for quantitative analysis and screening. Giles Scientific 416
