centrating nanogram quantities of DNA and isolating DNA without phenol extractions or ethanol precipitation. Also included are a product guide with ordering information and a price list. 12 pp. Amincon 419

Synergy personal peptide synthesizer automatically makes 30-60 mg of peptides up to 30 amino acids long following a 10-min setup procedure. A feedbackmonitoring system manages the synthesis to extend difficult couplings and ensures the quality of each peptide. Applied Biosystems 414

F u m e e x t r a c t i o n . SC-1 portable system removes gases, fumes, aerosols, and particulates generated in laboratory, QC, pharmaceutical, and R&D processes. Applications include source e x t r a c t i o n , p o r t a b l e fume hood exhaust, or direct line coupling to the exhaust hood of process equipment. Purified microEnvironments 411 SPE. Spe-ed Wiz Model 6035 automated SPE sample processor handles 35- and 60 -mL SPE cartridges as well as smaller standard cartridges. Twelve different solution volumes for wash, condition, and elution phases of sample processing can be controlled, and up to 30 samples can be processed in 30 min. Applications include a u t o m a t i n g e n v i r o n m e n t a l sample analysis and screening biological samples and fermentation broths. Applied Separations 412 Spectrometer. MB 157 FT-Raman/ F T - I R s p e c t r o m e t e r , b a s e d on near-IR excited Raman scattering, retains optimal efficiency in both IR and Raman operation. Changing between IR and Raman measurements, which requires < 1 min, involves interchange of prealigned detectors and switching from internal to external interferometer input beam. Bomem 413 M e r c u r y d e t e r m i n a t i o n . PS200 automated mercury analyzer consists of a mercury cold vapor doublebeam detector with pptr sensitivity, random-access autosampler, IBMcompatible PC, and software. Up to 88 individual samples, six calibration standards, and seven quality control
