Soxtec™ ST243 Extractor

Labtec™ Line Extraction System – Soxtec™ ST243 (manual)

Soxtec™ solvent extraction systems for safe, convenient and economical determination of soluble, or extractable, matter. Typically five times faster than classical Soxhlet equipment, Soxtec™ systems provide rapid analysis with absolutely no loss in precision or accuracy. Soxtec™ 200 series comprises 2 different solvent extraction systems (ST 255 and 243) and a unique, patented hydrolysis unit (SC 247 SoxCap™) for hydrolysis including filtration and washing.

The ST 243 Soxtec™ is a six-place solvent extraction system used for fast and safe determination of extractable matter in food, feed, soil, polymers, paper pulp and textiles. The system comes with an extraction and control unit as well as 26 mm/30 ml cellulose thimbles.
