Dry Fixed-Volume Nitrogen Evaporator OLB-QDC-4G, 4 Sample Positions (CAT#: STEM-AL2-1570-ZJF)

The Dry Fixed-Volume Nitrogen Evaporator is designed for controlled nitrogen-assisted sample concentration. It directs nitrogen over samples while controlling sample temperature to accelerate solvent evaporation. Its operating range, capacity, dimensions, materials, and control functions are retained only when stated in the source. Available variants are distinguished by the source-listed model and technical configuration. The equipment is intended for repeatable use in the stated laboratory or facility workflow. Control, alarm, safety, or data functions are included only where they are explicitly provided in the source. No unsupported numerical performance values are added to the normalized record. The entry is presented in a neutral technical format for cataloging, comparison, and selection.
