Soxtec? ST255 Extractor


Labtec? Line Extraction System –?Soxtec? ST255 (semi-automated)

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 semi-automated ST 255 Soxtec? is used for fast and safe determinations of extractable matter. It is ideal for laboratories with a lower throughput, offering many of the benefits and features of the fully automated Soxtec, but at a lower price. The system allows for a throughput of up to six extractions, 36 samples per day and includes batch handling tools that ensure fast and safe handling of samples and cups.
