Compost weighing biodegrader
Model: MODA-9
First, the use of the product
1. It can be used for biodegradability analysis of degradable plastics and other bio-based materials;
2. Meet GB/T 19277.2-2013;
3. Meet GB/T 22047-2008;
4. Meet ISO 14855.2-2018;
5. Meet ISO 17556-2012;
Second, product features
1. The sample degrades in the active compost and the air passes through the active compost under controlled conditions;
2. The released ammonia and water are removed, and the released carbon dioxide is absorbed by sodalime (sodium hydroxide);
3. The carbon dioxide released is calculated by the weight increase of soda lime;
4. The reaction column can be controlled at the temperature specified by the user;
5. Samples are weighed regularly during the test;
6. If the ISO14855-2 is satisfied, the temperature is usually kept at 58°C;

Third, the principle of the product
Under the condition of 55-60 degrees Celsius, the air that removes carbon dioxide is continuously supplied to the reaction chamber, and the sample to be analyzed in the reaction chamber is biodegraded by respiration under the action of microorganisms, and the oxygen is discharged into carbon dioxide through respiration and absorbed by soda lime, and we calculate the biodegradation rate of the sample by weighing the change in the weight of soda lime.
