The EcoFlex™ Permeation System is designed for creating trace concentration gas mixtures. Mixtures are produced by diluting the minuscule flow of vapor emitted by Trace Source™ permeation (or diffusion) tubes with a much larger flow of inert matrix gas, typically nitrogen or zero air. Mixtures contact only suitably inert materials, Teflon®, coated stainless steel, or glass. The EcoFlex™ manual system is built on the same readily transportable platform as the microprocessor controlled FlexStream™ Base Module. The EcoFlex™, however, is a simple, stand-alone, non-expandable, single oven permeation system.

The EcoFlex™ Gas Standard Generator System provides:

· Modes of Operation: span only

· Flow path suitable for reactive gases – mixture contacts only glass, Teflon® and stainless steel (other materials available)

· Accepts disposable permeation tubes, diffusion tubes, wafer tubes, and prefilled gas fed permeation tubes

· Single-oven module can create mixtures with up to 8 components: Accepts up to 8 disposable tubes with maximum 6 inch length x 1/4 inch diameter (KIN-TEK HRT, SRT and EL tubes)

· Accepts one of KIN-TEK refillable LFH, or Prefilled 57S

· High mass oven with electronic PID control
