SPE-DEX 4790 Automated Extraction System from Horizon Technology, Inc.


The SPE-DEX 4790® Automated Extraction System is a fully automated sample preparation system designed to rapidly process samples for trace level analysis of organic chemical contaminants from aqueous samples. The system comes pre-programmed with United States EPA methods and also easy programming for custom methods.

The SPE-DEX® 4790 Extraction System uses Solid Phase Extraction (SPE) technology to replace the conventional, labor-intensive liquid-liquid extraction (LLE) technique. In addition to delivering accurate, more consistent results, SPE technology slashes labor costs, sample processing times, and solvent use.

Solvent consumption is cut by up to 90% compared to traditional liquid-liquid extraction methods. Sample run times are less than 5 minutes.

Unattended operation increases the overall productivity of your lab as personnel are freed up for other projects. Plus variability between chemists' techniques is eliminated. The SPE-DEX® 4790 Extractor processes samples directly from the original sample bottle.It automatically delivers all solvents, regulates sample processing and disk drying times, rinses the sample bottle and collects the extract.

  • Modular design 1-8 extraction stations - each station runs independently
  • Extracts a wide range of aqueous samples: Clean and Particulate - ""dirty"" samples
  • Interchangeable 47 mm, 50 mm, 90 mm SPE disk holders to accommodate a variety of SPE disks
  • Handles sample volumes from 20 ml to 4 L
  • Bench-top operation frees up valuable hood space
  • Automatic sample bottle rinse
