Overview
The CD-9 Digester is a 9-well Digester from the QIWEI brand. It is mainly used for sample digestion reactions with the QW-CD-T/B chemical oxygen demand analyzer. It is suitable for chemical oxygen demand (COD) analysis and is also suitable for other applications.
Features
Compact in structure, 25 sample digestion reactions can be performed simultaneously, greatly reducing energy consumption.
2. The digestion method of sealing micro-reflux is adopted, and no condensation water is required.
3. Digestion temperature 45-190 ℃ arbitrary setting, and over-temperature alarm device, easy to use.
4. The digestion time can be set arbitrarily from 0 to 720 minutes, and it will automatically turn off after the reaction, which is easy to operate.
5. Each testtube has been tested for pressure and heat resistance, which is safe and reliable.
Principle
The instrument adopts the digestion method of sealing microreflux to heat the sample under the set temperature and time conditions.
Applications
Chemical Oxygen Demand (COD) Analysis, Miscellaneous Sample Digestion
Steps
1. Set the required digestion temperature (45-190 ° C).
2. Set the required digestion time (0-720 minutes).
3. Start the instrument for digestion reaction.
4. The instrument automatically shuts down after the reaction.
Notice
• Ambient Temperature should be between 5 and 40 ℃.
• The relative humidity of the working environment should be ≤ 85RH.
• Power supply voltage should be AC220V +/- 10% (50Hz +/- 2Hz).
• The instrument has an over-temperature alarm device, please pay attention to the safety of use.
