BUCHI - Model E-800 -Universal ­Extractor

Six distinct extraction positions enable individual process control and simultaneous operation of different extraction methods, so you can execute multiple work packages in parallel. With the powerful and perfect for multitasking UniversalExtractor E-800, you can develop methods faster and boost your sample throughput.

Obtain the highest analyte recoveries thanks to a unique analyte protection feature, which ensures that always a minimal level of solvent is found in the beaker. The UniversalExtractor E-800 prevents the deterioration and degradation of heat-sensitive analytes during all process steps and ensures safe and reproducible concentration of the extract.

All components in the UniversalExtractor E-800 that are in contact with the sample and the solvents are made of completely inert materials. With our system, you eliminate the risks of sample contamination and any memory effects from leaching materials. You can select the inert gas supply at all process steps (extraction, rinsing, drying) to protect the analyte against oxidation. Inert gas is automatically switched on if the analyte protection sensor is triggered.

Analyte protection sensor

The analyte protecion sensor monitors the solvent level in the beaker and prevents the beakers from running dry, so your process is safer and your heat-sensitive analytes are well-protected.

The large condenser captures vapours efficiently and ensures highest solvent recovery (> 90 %), even with volatile solvents. Any emission of vapours is eliminated and allows for operation outside of the fume hood.

The entire extraction process is visible. The glass assemblies can be easily accessed and disassembled for cleaning and for decontamination in the oven (baking out at + 450 °C).

You can readily achieve the detection limit of the analyte by using the LSV glass assembly with the larger extraction chamber and beaker designed for higher sample quantities. The LSV glass parts are 60% larger than the standard version.
