SPE-DEX^® 4790 Automated Extraction System

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 using United States EPA methods for Solid Phase Extraction (SPE).

The Spe-Dex 4790 Extraction System uses Solid Phase Extraction (SPE) technology to replace the old, labor-intensive liquid-liquid extraction (LLE) technique. In addition to delivering accurate, more consistent results, SPE technology slashes both 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.

The Spe-Dex 4790 Extraction System features:

Bench-top operation frees up valuable hood space
Modular design allows for addition of up to seven extraction stations
Interchangeable 47 mm, 50 mm, 90 mm SPE disk holders
Handles sample volumes from 20 ml to 4 L
