Hach Chemistries and Instruments are Designed as a System. Only Hach chemistries and instruments are designed to work as an integrated system, eliminating calibration and variability errors from the outset so you can be certain of your results. Using both, ensures accurate results the first time, every time.

1. 300 ml BOD bottles. 2. 2 - 5 liter glass bottle with siphon. Avoid using detergents to clean these bottles. Periodically clean with bleach water. 3. 20 ( 1(C incubator. 4. DO meter. 5. Buret. Nutrient Solutions: 1. Phosphate buffer: Dissolve 8.5 g KH2P04, 21.75 g K2HP04, 33.4 g Na2HP04(7H20, and 1.7 g NH4Cl in approx. 500 ml reagent water

A COD standard solution (100 mg/L) in water obtained from VWR was used to test the accuracy and precision of this method. An oven (or thermoreactor) was preheated to 148 oC. After removing the screw cap from a COD vial, 2.0 ml of the 100 mg/L COD standard was placed in the vial, the cap replaced, and the contents mixed vigorously.

Kits contain leak-proof vials. Caps provide a positive seal that traps volatile material and ensures complete digestion. Reagents are premixed, minimizing dangerous spills and handling of corrosive and toxic chemicals. Small reagent volumes mean less silver and mercury waste. Pack of 25 reagent vials. ACCESSORIES.

24. Hach Company Chemical Oxygen Demand (COD) TNTplus Vial Test, LR (3-150 mg/L COD), 25 Tests. Hach TNTplus COD vial test reagents are incredibly simple to use and cut down significantly on waste generation compared to other COD test kits. TNT821 is based on Hach Method 8000 for virtually any type of water sample.

Pre-filled with COD reagents, these digestion vials come in either EPA-approved or mercury-free versions for low-, standard-, and ultra-high-range analysis. Each lot is tested to ensure superior quality from the cap and vial to the chemical contents. Glass vials are 16 mm x 100 mm to work with your existing COD reactor and spectrophotometer.

COD & BOD. Chemical and biological oxygen demand are used extensively in the waste water industry to measure the amount of organic compounds in waste water. Items 1 - 16 of 192. Show.

Reagents are chemicals formulated to react with specific ions causing them to change color. For the purpose of water quality analysis, test samples are put in a cuvette (sample container) to which reagents are added. If the compound specific to the reagent is present, the reagent will turn it a color.

High quality COD reagent vial factory water analysis 16mm Test Tube COD Glass Vial with Screw cap and septa Product Description The Chemical Oxygen Demand ( COD ) test is widely used as a measure of organic contamination by determining the quantity of oxygen required for oxidation of reduced species including organic matter, in a water sample

HI839800 COD Test Tube Heater using the HI93754C-25 High Range COD Reagents. The sample is prepared for titration the same way as for a colorimetric test: a blank is prepared by adding 0.2 mL of deionized water to a reagent vial, and samples are prepared by adding 0.2 mL of sample to a reagent vial. Both the blank and
