Swiss laboratory equipment supplier Buechi's new SpeedExtractor offers an efficient solid-liquid extraction method, using high temperature and pressure to accelerate the extraction process and to reduce the solvent consumption.
With its parallel format, up to six samples can be extracted simultaneously within approximately 20-40 minutes. The extraction cells are sealed automatically, which the company says provides a high degree of safety and eliminates handling errors.
Flexibility is provided by a temperature range of 50-200°C, a pressure range of 50-150 bar, and extraction cell sizes of 10-120 ml.
The SpeedExtractor's parallel format is complemented by the parallel evaporator Syncore Analyst. This paired system allows for collection vessels to be transferred directly and therefore without any sample loss, and to be concentrated in parallel to pre-defined residual volumes.
The key feature of the Syncore Analyst is an integrated cooling zone, which stores the sample in a cooled environment. Buechi says the risk of cross-contamination is eliminated by an individual sample sealing system and by separated vacuum channels.
The Syncore Analyst offers efficient and parallel concentration in less than one hour while solvent recovery reduces the environmental impact of the system, making it the system of choice for concentration down to pre-defined residual volumes in trace and ultra-trace analysis.
Buechi also offers Extraction System B-811, which allows different extraction techniques (Soxhlet Standard, Soxhlet Warm, Hot Extraction and Continuous Extraction) to be performed in one instrument without conversion of the glass assembly. Each technique follows a fully automated extraction process consisting of extraction, rinsing and drying. The equipment is designed for unattended operation and minimum system handling.
Buechi says all instrument components in contact with solvent/sample/analyte are fully inert, which eliminates residual effects and ensures low and stable blank values.
