“We bought six CSTR-5S reactors, six gas flow meters and one data logger for our pilot-scale experiments on anaerobic digestion of biowaste... All instruments are very easy to handle. We can easily set up an automatic feeding and discharging system which minimises the labour-demand for the experiment follow-up… The design of gas, liquid and solid in/outlets are suitable for our experimental needs. No blockage issue has ever been experienced. We are fully satisfied by BPC Instruments pilot scale solution, it earns us some envious looks from colleagues :-)”
