Biometer, measuring carbon dioxide

Figure 3. Biometer for Measuring Carbon Dioxide Evolution in Biodegradation Testing.

Biodegradation testing was done in the biometer described in Figure 3. The environments of choice were mixed with the plastic or degradation products and the rate and degree of carbon dioxide evolution measured by capture in the reservoir of caustic soda solution. 

Biodegradation experiments were carried out in compost and soil environments using the biometer shown in Figure 3 to follow and measure the rate and extent of degradation through monitoring carbon dioxide evolution.
