NEW GASCO REFILLABLE CALIBRATION GAS CYLINDER DELIVERS 100% MORE CAPACITY THAN 58-LITER DISPOSABLES

OLDSMAR, Fla. – May 2007 - Gasco Affiliates, LLC, a leading producer of precision calibration gas, equipment and accessories, has introduced ecosmart, a new 116-liter refillable, portable cylinder that delivers 100 percent more capacity than the standard 58-liter disposable cylinders and reduces end-user costs. ecosmart holds both pure gases and mixes.

While ecosmart holds 100 percent more calibration gas than the disposable 58-liter cylinders, it remains lightweight and fits into the standard carrying case. Since the end user is paying for only one cylinder instead of two, it dramatically reduces end-user costs. If the cylinder is refilled, end-users can achieve an additional financial advantage. Refillable cylinders are simply returned to Gasco.

Thomas Hanway, Gasco founder and managing member, says ecosmart reflects the company’s commitment to meet the needs of the analytical equipment industry. “Our new 116-liter refillable cylinder allows distributors and end users to enhance utilization by reducing interruption and costs; it’s a win-win situation.”

Founded in 1996, Gasco Affiliates, LLC is a leading producer of precision calibration gas, equipment and accessories. The company employs proprietary procedures to create the highest quality grades of pure gases, gas mixtures – single gas, complex four-gas and
highly reactive gas mixtures – cylinders and accessories for a wide range of applications. Gasco products meet or exceed all safety equipment industry specifications, and are available exclusively through safety distributors worldwide. For more information, visit www.gascogas.com.
