Detonation bomb calorimeter 6790 series

The 6790 is a detonation bomb calorimeter that is specifically used in measuring the heat of combustible or reactive materials in oxygen or inert atmospheres. Powerful vessels often have difficulty in detonation small amounts of extremely reactive materials. The standard heat of combustion of PETN in oxygen reaches 1975 calories per gram while the heat of the detonation in vacuum peaks at 1490 cal/gram. For the 6790, its construction consists of a spherical-like detonation vessel that measures 3.2 cm in thickness and is made out of stainless steel. It possesses an inside diameter of 21.6 cm and an internal volume of 5.3 liters.
