This document discusses Enviro-Clean (EC) products which are designed for environmental and agricultural testing labs. It summarizes that EC products are "cleaner" as they have cleaner frits, no detectable plasticizers from cartridges, cleaner sorbents, and cleaner packaging. They are designed to exceed customer needs for quality. Several EC products are then described, including Teflon stopcocks, universal cartridges and accessories, and an oil and grease analysis cartridge. The document notes that EC products can save time, provide consistent results, and cleaner extracts compared to in-house preparation of samples.
