cmc Instruments NGM11 Nitrogen Membrane Gas Generator for Laboratory and Industrial Use

The cmc Instruments NGM11 is a nitrogen membrane gas generator engineered to provide a continuous supply of high-purity nitrogen gas suitable for laboratory and industrial environments. Utilizing advanced _membrane separation technology_, this generator efficiently extracts nitrogen from compressed air, delivering nitrogen gas with purity levels up to 99% N₂.

Key features include:

• _Membrane-based nitrogen generation_ optimizing gas purity without chemical adsorbents
• Typical flow rates ranging from 10 to 15 liters per minute depending on model specifics
• Requires compressed air input at approximately 7–10 bar pressure, with nitrogen output pressure around 5–6 bar
• Integrated multi-stage filtration system including oil, water, and particulate filters to ensure contaminant-free gas output
• Designed for continuous operation with low maintenance demands, energy efficiency, and quiet performance
• Compact dimensions (approx. 45 × 45 × 90 cm) and moderate weight (~50 kg) enable convenient installation in lab or production environments
• Electrical supply: 230 V, 50/60 Hz; fitted with standard air and nitrogen connections (1/4" or 1/2" NPT/BSP)

This generator is essential for molecular diagnostics, bioprocessing, and synthetic biology research workflows, particularly as an inert gas source for analytical instruments such as Gas Chromatography (GC), Liquid Chromatography-Mass Spectrometry (LC-MS), and Fourier Transform Infrared Spectroscopy (FTIR). It supports sample preparation, inertization, and protective gas supply, making it a critical component in biopharmaceutical production pipelines and biotechnology laboratories.

Its robust membrane technology and continuous operation capability make the NGM11 a reliable and widely adopted nitrogen supply solution for biomedical engineering, clinical diagnostics, and other research fields requiring stable, high-purity nitrogen. The system eliminates dependency on external gas cylinders, improving workflow efficiency and safety in laboratory gas management.

This particular unit is in very good used condition, suitable for integration into existing analytical setups or new installations focused on biotechnology and chemical analysis.
