Overview
The COD-25 digestion instrument is a COD rapid digestion instrument under the QIWEI brand. It is mainly used for sample digestion reaction during chemical oxygen demand (COD) analysis when matched with the QW-COD-T/B chemical oxygen demand analyzer. The instrument has a compact structure and can handle 25 samples simultaneously. It is also suitable for Miscellaneous applications that require digestion reactions.
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 uses the digestion method of sealing microreflux to heat and digest the sample. After the user sets the required digestion temperature (45-190 ° C) and time (0-720 minutes), the instrument thermostatic heats the sample, completes the digestion reaction under sealing conditions, and automatically stops working after the reaction is over.
Applications
Chemical Oxygen Demand (COD) Analysis Sample Digestion and Laboratory Application of Miscellaneous Digestion Reaction
Steps
1. Set the required digestion temperature (45-190 ° C).
2. Set the required digestion time (0-720 minutes).
3. Place the sample and start the instrument for digestion reaction.
4. After the reaction is completed, the instrument automatically shuts down.
Notice
• Ambient Temperature should be between 5 and 40 ℃.
• Working environment relative humidity should be ≤ 85% RH.
• Power supply voltage should be AC220V +/- 10% (50Hz +/- 2Hz).
