The C 1 static jacket oxygen bomb calorimeter represents a giant leap forward in calorimeter technology by featuring a high degree of automation in a compact design; the smallest calorimeter footprint available. It operates according to DIN 51900 and ISO 1928. The temperature readings are analyzed according to the classical isoperibol method of Regnault Pfaundler. The traditionally known, comparably heavy screw threaded decomposition vessel, has been replaced by a light and easily attachable combustion chamber. Due to the variety of different interfaces (PC, balance, printer) this unit is easily adaptable depending on the customers specific application needs. Further adaption to data management and LIMS is possible with our calorimeter software C 6040 Calwin (Accessory). The C 1 Package 1/10 contains the C 1 Calorimeter (inclusive standard combustion chamber C 1.10) and the cooling water supply unit KV 600 NR. The unit contains all parts necessary to set up the unit. We also supply wear parts and consumables for the first approximately 500 experiments including 25 calibrations. The C 1.10 combsution chamber is equipped with the C 5010.5 large crucible holder and C 6 large quartz crucible.
