Haverhill, MA, October 3, 2007 – Dangerous and expensive cylinders of hydrogen fuel gases can now be eliminated by using a Balston brand hydrogen gas generator.

The Parker Balston® NitroFlowLab is a self contained membrane nitrogen generator that produces 99% pure nitrogen with pressures up to 116 psig. It produces nitrogen by utilizing a combination of compressors, filtration, and membrane separation technologies. High and low pressure compressors carefully matched to hollow fiber membranes subsequently separate the clean air into a concentrated nitrogen stream and oxygen enriched permeate stream, which is vented from the system.

The combination of these technologies produces a continuous on-demand supply of pure nitrogen. Typical applications include nebulizer gases, curtain gases, source gases, chemical and solvent evaporation, instrument purge and supply, evaporative light scattering detector use and sparging.

Parker Hannifin Corporation is the worldwide leader in separation and filtration technology, and offers a broad range of gas generators to meet your specific analytical instrument requirements.

All products are backed by a fully staffed sales and service organization and come with a standard one-year system warranty and two-year compressor warranty.

With annual sales exceeding $10 billion, Parker Hannifin is the world's leading diversified manufacturer of motion and control technologies and systems, providing precision-engineered solutions for a wide variety of commercial, mobile, industrial and aerospace markets. The company employs more than 57,000 people in 46 countries around the world.
