Inexpensive Flow Microcalorimeter For Measuring Heat Production of Attached and Sedimentary Aquatic Microorganisms
AUTOR(ES)
Lock, Maurice A.
RESUMO
A relatively inexpensive flow microcalorimeter is described which is capable of detecting heat outputs as low as 3 μW (precision, ±2%). Its use is illustrated on river epilithon (0.8 to 6.8 μW cm−2), river sand (9.8 μW cm−3), and marine sand (15.3 μW cm−3); however, it could be used to detect the heat output from any biotic material over which a flow of water can be passed, provided that such an action would not be disruptive to chemical and biological equilibria.
