convenient testing Capped 16-mm vials provide a self-contained package for mixing and measurement. Easy ordering All necessary reagents and vials are contained in the package. Perform digestions and photometric measurements in the same

The vials are allowed to cool in a vial rack, after which time they can be measured using a photometer or spectrophotometer that accepts 16mm diameter cells. CHEMetrics COD vials can be directly used in our V-2000 multi-analyte photometer , CHEMetrics' single analyte COD photometers , as well as in many Hach† spectrophotometers and colourimeters (see pdf below for complete list).

Chemical Oxygen Demand (COD Vials) LR COD: 0 - 150 mg/L HR COD: 0 - 1500 mg/L HR+ COD: 0 - 15,000 mg/L SAFETY INFORMATION COD reagent vials contain sulfuric acid, which causes severe burns. Read the SDS (available at www.chemetrics.com)

Wet Chemistry: Chemical Oxygen Demand (COD) Environmental Express offers COD Standards in 1,000 and 10,000 ppm. Standards are made from primary standard grade potassium hydrogen phthalate and can be used with both the EPA approved vials and

Oxygen Demand, Chemical Oxygen Demand, Chemical Page 3 of 10 Calculate the multiplication factor All dilutions require that the ratio of sample to sulfuric acid remain at 9:1. For other dilutions that are not listed in the Multiplication factors table, add the sample volume and the deionized water

Tubes and vials are supplied in a range of heights, diameters, wall thicknesses, bottom shapes (round or flat), rim and closure styles in capacities from a few microlitres up to 25mL. Closures can be simple stoppers, screw-tops, push-tops, snap-tops or crimp-tops.

Specifications. Description. 16mm Hach vials for vials for Chemical Oxygen Demand ( COD ) determination. Results displayed as O2 mg/l. Please note a reactor is required for sample digestion. The tube tests are in high-quality glass and the reagent tubes are shipped in special packaging to protect them during transport.
