BIOSCIENCE CHEMICAL
OXYGEN DEMAND
For determination of the quantity of oxygen required to oxidize reduced
compounds, including organic matter, in a water sample using
EPA-approved micro C.O.D. method (US EPA Method 410.4). Test involves
mixing sample with a specific oxidizing agent and catalyst, digesting 2
hrs. at 150°C, followed by spectrophotometric measurement of absorbance.
The 16mm O.D. borosilicate glass digestion tubes are of high optical
quality with uniform glass walls. Come pre-filled with sufficient
digestion reagent for low, standard or high C.O.D. range samples.
Supplied with leak-resistant screw caps. Tubes are packed in modular
packs for easy stacking.
Designed for samples with low chloride and ammonia levels. Mercury-free
reagents are available for non-reporting purposes. Sturdy, compact
C.O.D. heater blocks automatically maintain correct digestion
temperature of 150° ±2°C, (302° ±3.6°F) and operate with simple on/off
power switch. Available for 15 or 30 tubes. Use screw-cap digestion
tubes. 16mm tube adapters for popular spectrophotometers and C.O.D. data
management software sold separately. Heater Block Dimensions, 15 Tube:
22.2W x 21.4D x 9.2H cm (83/4 x 81/2 x 35/8”) 30 Tube: 21.6W x 29.8L x
8.9H cm (81/2 x 113/4 x 31/2”) Electrical: 110V or 220V, 50/60Hz, 150W |
