In Stock - Ships within 1 week. Contains mercury. Dispose of according to local, state and federal regulations. For determination of low range Chemical Oxygen Demand (COD) by the Reactor Digestion method. US EPA approved for wastewater analysis using Hach Method 8000. Range: 3-150 mg/L COD. Pack of 150 vials.

Jul 15, 2017 · The COD was estimated using a close reflux colorimetric method involving the addition of 2 mL samples to High Range COD Digestion vials (20–1500 mg L −1, HACH Pacific, Australia). The vials were heated at 150 °C for 2 h and absorbance was read against a blank with a spectrophotometer (HACH DR2010; method 435).

Jul 04, 2018 · complete digestion (Supporting Information, Figure S1). At the start of the experiment, 45 mL of the digestion medium (37 °C) and 1.25 g of LBF (preheated to 37 °C) were added and allowed to mix for 10 min (450 rpm). During this dispersion phase, the pH was manually adjusted to 6.5 ± 0.05. Digestion

COD Reactor for Digestion Vials. A COD reactor is used to heat the digestion vials. The digestion vials must be heated to a specific temperature for a period time making the HI839800 an important accessory required to have a complete wastewater treatment monitoring system.
