With a measurement range of <strong>0\u20135.00 ppm<\/strong>, this test kit ensures accurate monitoring of free and total chlorine, making it ideal for water treatment, environmental testing, and industrial applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike traditional visual test kits, the Vacu-vials system allows for <strong>direct reading on CHEMetrics Direct-Read Photometers<\/strong> or any <strong>spectrophotometer compatible with 13 mm round cells<\/strong>, providing fast and reliable results with minimal operator error.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Why Choose Vacu-vials?<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Instrumental Accuracy:<\/strong> Obtain precise readings using a photometer or spectrophotometer.<\/li>\n\n\n\n<li><strong>Safe and Sealed:<\/strong> Each ampoule is vacuum-sealed to prevent reagent degradation and reduce direct chemical contact.<\/li>\n\n\n\n<li><strong>Simple Operation:<\/strong> Minimal steps reduce the likelihood of operator error.<\/li>\n\n\n\n<li><strong>Compatible with Other Equipment:<\/strong> Can be used with third-party spectrophotometers by selecting the wavelength specified in the kit instructions.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">How It Works<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The K-2513 Chlorine Vacu-vials use the <strong>USEPA-approved DPD (N,N-diethyl-p-phenylenediamine) method<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Free Chlorine:<\/strong> DPD reacts with free chlorine in the water to produce a <strong>pink-colored product<\/strong>.<\/li>\n\n\n\n<li><strong>Total Chlorine:<\/strong> When combined chlorine (chloramines) is present, the kit includes an <strong>A-2500 Activator Solution (potassium iodide)<\/strong> to measure total chlorine, accounting for both free and combined forms.<\/li>\n\n\n\n<li><strong>Hypochlorite Testing:<\/strong> The DPD reaction is also applicable for measuring hypochlorite concentrations in cleaning solutions and disinfectants prior to dilution, with results expressed as <strong>percent (%) NaOCl<\/strong>.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">How to Use the K-2513 Vacu-vials<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Fill the Sample Cup:<\/strong> Add water sample to the 25 mL mark of the included sample cup.<\/li>\n\n\n\n<li><strong>Add Stabilizer Solution:<\/strong> Add <strong>2 drops<\/strong>, and stir to mix.<\/li>\n\n\n\n<li><strong>Fill the Vacu-vial:<\/strong> Place the ampoule <strong>tip-first<\/strong> into the sample cup, snap the tip, and it will automatically fill.<\/li>\n\n\n\n<li><strong>Mix the Ampoule:<\/strong> Tilt side-to-side to move the air bubble and ensure proper mixing.<\/li>\n\n\n\n<li><strong>Wait for Color Development:<\/strong> Dry the ampoule and wait <strong>2 minutes<\/strong> for the color to develop.<\/li>\n\n\n\n<li><strong>Read Results:<\/strong> Insert the Vacu-vial into the photometer <strong>flat-end first<\/strong> to obtain the reading in ppm Cl\u2082.<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Kit Contents<\/h2>\n\n\n\n<ul
