LC-NA-300 Nitrogen-Air Generator, 300 mL/min Nitrogen and 3 L/min Air (CAT#: STEM-BC-4108-ZJF)

The LC-NA-300 is an integrated nitrogen and air generator for laboratory gas supply. It combines a high-purity nitrogen generator and an air generator in one compact instrument. The unit is designed for connection to gas chromatographs and can replace conventional compressed-gas cylinders. Its nitrogen system uses a multilayer plate structure and repeated purification to improve gas purity. The air system incorporates three-stage purification, two-stage pressure stabilization, and multiple protection measures. Nitrogen and air can be generated independently or at the same time. An LCD and pressure gauge provide clear operating information. A liquid-backflow prevention device protects the nitrogen section during operation. Routine use requires only the addition of distilled water, simplifying daily maintenance.
