The COD-25 digestion instrument is a laboratory instrument designed specifically for sample digestion in conjunction with the QW-COD-T chemical oxygen demand analyzer. It is mainly used for the digestion reaction of samples during chemical oxygen demand (COD) analysis and is also suitable for other purposes.

Main characteristics of the instrument

1. The structure is compact and can simultaneously perform 25 sample digestion reactions, greatly reducing energy consumption.

2. Only 3ml of water sample is needed, and only 7.5ml of specialized reagent needs to be added to the test tube, which can save a lot of reagents.

3. Adopting a sealed micro reflux digestion method without the need for condensation water.

4. The digestion temperature can be set arbitrarily between 45-190 ℃, and there is an over temperature alarm device for easy use.

5. The digestion time can be set arbitrarily between 0-720 minutes, and it will automatically turn off after the reaction is complete, making the operation simple.

6. Each test tube undergoes a pressure and heat resistance test, ensuring safety and reliability.
