Vacuum Parallel Concentrator VPE-20, 20 Positions (CAT#: STEM-AL2-0435-ZJF)

The VPE-20 is a vacuum parallel concentrator for simultaneous solvent evaporation from multiple samples. It combines reduced pressure, water-bath heating, and oscillation to increase solvent evaporation. Twenty sample positions are independently sealed and use independent flow paths to reduce cross-contamination from bumping or backflow. Optional concentration vessels are listed at 50, 100, 200, and 250 mL. PID temperature control supports water-bath operation from ambient temperature to 100 °C. A double reflux-condensation arrangement collects evaporated solvent and provides a rapid waste-liquid drain. A corrosion-resistant diaphragm vacuum pump supports operation with solvent vapors. The narrative lists a 10.1-inch display while the technical parameter block lists a 15.6-inch color touchscreen, so the display size is retained as a source inconsistency.
