product key technologies
Model COD-25 and COD-9 digesters are special laboratory instrument for sample digestion with QW-COD-T/B chemical oxygen demand analyzer. It is mainly used for sample digestion reaction in chemical oxygen demand (COD) analysis, and is also suitable for other uses.
1. The structure is compact, and the digestion reaction of 25(or 9) samples can be carried out at the same time, which greatly reduces the energy consumption.
2. The digestion method of sealed micro-reflux is adopted, and there is no need for condensation of condensation water.
3. The digestion temperature can be set arbitrarily from 45 to 190 ℃, and there is an over-temperature alarm device, which is convenient to use.
4. The digestion time 0-720 minutes can be set arbitrarily, and it will be automatically closed after the reaction is over, so the operation is simple.
5. Each tube has passed the pressure and heat resistance test, which is safe and reliable.
