Weighing method biodegradation instrument

Brand:Thmorgan
Model:M1200W

Use of a product

1. Meet the test requirements of GB/T19277.2 standard;

2. Can be used for composting biodegradability detection;

3. Weighing method to detect carbon dioxide production;

4. Suitable for biodegradability determination of bio-based, plastic and other products;

 

Two product characteristics

1. Carbon dioxide emission of the sample was determined by gravimetry;

2. Air bath temperature control, temperature adjustment accuracy up to ±0.1℃;

3. Carbon dioxide generation is determined by weighing method;

4. 12-channel detection system, high experimental efficiency.

 

Principle of three products

This experiment system simulates the process of biodegradation of bio-based materials under aerobic composting conditions. Under aerobic environment, microorganisms consume oxygen and produce inorganic substances such as carbon dioxide and water by using bio-based materials as carbon sources. The generated carbon dioxide is absorbed by alkaline absorption column, and the increased weight is the carbon dioxide released by biodegradation of the sample. The biodegradation rate is the percentage of the carbon dioxide released by the sample biodegradation and its theoretical carbon dioxide release.
