Small Nitrogen Making Machine For Laboratory

In laboratory research, a stable and reliable supply of high-purity nitrogen is fundamental to ensuring smooth experimental operations. The small nitrogen making machine for laboratory is specifically developed to address the challenges of limited lab space, moderate gas demand, and strict purity requirements. It generates nitrogen directly from compressed air, replacing traditional gas cylinders and providing a continuous, dependable gas source for laboratory use.

How It Works

This compact laboratory nitrogen generator operates on Pressure Swing Adsorption (PSA) technology with carbon molecular sieves. The working principle is as follows:

• Compressed air passes through precision filters to remove oil mist, dust, and moisture
• Purified air enters the adsorption tower, where carbon molecular sieves selectively adsorb oxygen, allowing nitrogen to pass through
• Dual-tower design enables alternating operation – one tower adsorbs while the other regenerates
• Continuous, stable nitrogen output with adjustable purity settings

The entire process runs at ambient temperature and low pressure, requiring no heating and involving no chemical reactions, ensuring safe and reliable operation.

Technical Specifications

Product Features & Advantages

Compact Design, Space-Saving

The small nitrogen making machine for laboratory features an integrated design with a footprint comparable to a standard lab bench. Equipped with swivel casters, it can be easily moved according to laboratory layout requirements, with no fixed installation needed.

Ready to Use, Simple Operation

A 7-inch touchscreen control system enables one-button start for automatic operation. Real-time display shows nitrogen purity, pressure, and flow rate, with automatic alerts for parameter abnormalities. Regular lab personnel can operate independently after basic training.

Energy-Efficient, Low Operating Cost

Compared to traditional liquid nitrogen dewars or cylinder nitrogen, on-site generation offers significant cost advantages. The optimized energy design consumes only 0.3-0.5 kWh per cubic meter of nitrogen produced. Routine maintenance simply requires periodic filter element replacement, with clear replacement intervals and manageable maintenance costs.

High Purity, Excellent Stability

Nitrogen purity can be adjusted according to experimental requirements, reaching up to 99.999%. Built-in purity monitor provides real-time feedback, ensuring consistent output quality. Particularly suitable for demanding applications such as gas chromatography, mass spectrometry analysis, sample concentration, and solvent evaporation.
