High-purity nitrogen generator Mini Whisper

for LC/MSfor solvent evaporationfor mass spectrometers

Overview
The Mini Whisper Hybrid Nitrogen Generator is a compact membrane-based unit designed to supply filtered, dried nitrogen for LC‑MS and related laboratory applications, and for solvent evaporation. It separates nitrogen from compressed air with a low pressure drop, allowing connection to an existing dry, oil-free compressor in the lab.
