Calorimeter for the continuous study of the heat production of microbial systems

Abstract

The calorimeter described is suitable for the continuous study of the heat production of microbial systems. The instrument is self-balancing, heat production in a reaction vessel being simulated by electrical heating of an identical balance vessel. A continuous record of the electrical heat supplied to the system is presented on a strip chart. Provision is made for stirring, sampling and maintenance of a controlled atmosphere. The vessels may be sterilized and are inert towards the systems to be studied.
