Glass mass-flow sensors

Preparations, conducted at 40°C, take place in a stirred glass vessel equipped with sensors (pH, temperature, torque motor measurement of the stirrer shaft) allowing the control of the diffrrent steps of the preparation. Reactants pretreated at Ae preparation temperature, are introduced in the reactor at defined mass flow rates by means of calibrated peristaltic pumps. Reactants can be introduced in the reactor, successively (batch process) or simultaneously (semi-continuous process). In the later case reactants are mixed in the feeding pipe.
