Plastic Biodegradation Analyzer

MultiTalent PX2 The biodegradation analyzer can be widely used in various testing standards and is professionally applied to the aerobic environment degradation of plastics by microorganisms. It meets relevant domestic and foreign standards in various aspects such as experimental design, sample and inoculum processing, material sampling and storage, measurement principles, measurement indicators, experimental measurement devices, data collection, and data analysis and calculation. Directly test the oxygen consumption or determine the amount of carbon dioxide released, and calculate the biodegradation rate of the tested material by comparing it with the theoretical value.

Overall control throughout the experiment

This software supports users to monitor the status of each group of experiments in real-time during the experimental process. Users can also start, pause, and stop ongoing experiments and collect experimental data at any time with a simple operation.

Users can observe the cumulative aerobic curve and dynamic degradation curve trends of each reactor through the operation interface, and the data displayed on the graph has been calibrated to standard conditions (1 atmosphere, 0 ℃, 0 moisture content). With the help of the built-in Linux server application in the system software, users can monitor the progress of experiments and the running dynamics of each reaction bottle in real time from anywhere.
