FerroVer® Iron Reagent Pillows, pk/100

FerroVer Iron Reagent Powder Pillows are a long-standing staple of iron testing in water analysis, and this box delivers a generous pack of 100 single-use 5 mL pillows. Each pre-measured pillow is precisely dosed for a single test, which removes the guesswork and potential error of measuring out loose powdered reagent and helps every result stay consistent from one sample to the next. The FerroVer chemistry reacts with iron present in the water sample to produce a characteristic color, and the intensity of that color is read against a standard to indicate how much iron is present.

Iron is one of the most common and most troublesome contaminants found in well water across the country. It causes the reddish-brown staining that homeowners see on sinks, tubs, toilets, and laundry, imparts an unpleasant metallic taste to drinking water, and fouls softeners and filters, reducing their effectiveness and lifespan. Measuring iron accurately is the essential first step toward selecting the right iron filter or oxidation-based treatment system, and it is equally important afterward for confirming that the chosen treatment is actually working and keeping iron at acceptable levels.

• Generous pack of 100 single-use FerroVer reagent pillows
• Pre-measured 5 mL dosing for fast, repeatable iron tests
• Color development keyed to iron concentration in the sample
• Genuine Hach reagent for trusted method compatibility
• Convenient bulk supply for ongoing and high-volume testing
• Clean, no-measure format ideal for field work

The powder pillow format is especially well suited to field work and busy testing benches because it is fast, clean, and consistent, with no liquid reagent to measure or spill. Water treatment professionals, well owners, and operators rely on FerroVer to diagnose iron problems in the first place and then to verify iron removal once treatment is in place. For best results, store the pillows in a cool, dry location away from moisture, observe the expiration dating on the box, and follow the Hach method directions carefully to obtain accurate, dependable iron measurements every time you test. Because iron readings guide the selection between an oxidizing iron filter, an aeration system, or a softener-based approach, getting an accurate number at the outset can save a homeowner from investing in the wrong equipment, and retesting afterward provides the proof that the chosen system is genuinely keeping iron below the threshold where staining begins.
