the cod-25 digestion apparatus is a laboratory apparatus specially equipped with qw-cod-t chemical oxygen demand analyzer for sample digestion.
main features of the instrument
with compact structure, 25 sample digestion reactions can be performed simultaneously, which greatly reduces energy consumption.
only 3ml water sample and 7.5ml special reagent in the test tube can save a lot of reagents.
the solution method of sealing micro-reflux is adopted without condensation of condensed water.
digestion temperature 45-190 ℃ set arbitrary, and overtemperature alarm device, easy to use.
the digestion time is 0 to 720 minutes, and it will be automatically closed after the reaction. the operation is simple.
each tube has been tested for resistance to pressure and heat and is safe and reliable.
