Start off with the basic-level system containing the calorimeter, 1 x bayonet bomb vessel, air cooler and oxygen filling station, can complete up to 4 samples per hour, and grow your system as your budget grows to an standard system containing 1 air coolers (3K-2) and 2 bayonet bomb vessels (3K-5). The standard system can complete up to 6 samples per hour. Part of the CAL3K-F system is the external oxygen filling station (3K-3). The waterless cooler (3K-2) is a powerful air cooler with the ability to rapidly cool the bomb vessel, yet remain environmentally friendly. The sample repeat speed ranges between 7-8 minutes per sample, depending on the system configuration.
