Environmental Express MicroVials provide quality COD test results at a savings for your laboratory. Using MicroVials for COD analysis is quick and easy. Simply add two milliliters of sample to the vial, digest at 150°C for two hours and then read results directly on a spectrophotometer.
If you currently use the micro-COD digestion method, Environmental Express vials will provide equivalent results using equivalent calibration curves to the vials you currently use - no method modification necessary!
MicroVials are packaged in spectrally uniform 16mm glass cells that fit directly in all commercially available COD reactors and spectrophotometers. In fact, results provided by MicroVials will read directly on Hach® spectrophotometers without any method changes. Each lot of MicroVials is checked against NIST standards and against competing brands of COD vials. Best of all, Environmental Express MicroVials are priced up to 25% less than competing brands of vials. Vials are packaged in boxes of 100 and provided with MSDS, instructions and transmittance curves. Download EPA Method 410 in the News section of this website.
