Ball Valves and Sodium Hypochlorite: Sodium hypochlorite is inherently an unstable compound. As it decomposes, the resulting crystalline salts and oxygen gas can cause operational and safety issues with conventional ball valves. (read more)

Quantitative isolation of organically bonded halide as a prerequisite for classical potentiometric determination requires extraction of the halide from an organic medium into a water-soluble ionic form. The GFS Organic Halogen Reagent (Item# 5005) does this effectively and rapidly for samples that can be dissolved in an inert solvent,such as toluene or ether. (read more)

• Detection limit of 0.01 ppb (0 to 10,000 ppb)
• 100 days between reagent changes
• Automatic reactivation ensures optimum response time and performance; no acid etching required!

Available in the US and Canada only. (read more)

The ESA and OA metabolites of the six acetalinide (pesticide) compounds cited in UCMR II (Unregulated Contaminant Monitoring Rule, second cycle) are now available. This amendment to the Safe Water Drinking Act initiates monitoring of ESA and OA degradates for all large public drinking water systems. (read more)

The ion exchange water softener is one of the most common tools of water treatment. Its function is to remove scale-forming calcium and magnesium ions from hard water. In many cases soluble iron (ferrous) can also be removed with softeners. A standard water softener has four major components: a resin tank, resin, a brine tank to hold sodium chloride, and a valve or controller. (read more)
