The vessel body is stainless steel (on request 316 for halogen) and a pressed on aluminium sleeve which acts as a heat sink and temperature equalizer. This sleeve performs the task of the traditional water and stirrer. The mass of the new 4K-4 vessel was increased by 30% which results in higher energy release of samples.
The 4K-4 vessel can be used in any of the DDS calorimeters and coolers for effective routine sample determination. The speed of a determination depends on the type of calorimeter it is used in, the cooling method, the number of vessels, and other system variables.
Please note that other bomb vessels like the bayonet bomb vessel were supplied with our systems prior to 2023.
Vessel testing happens every time it is inserted into the bomb well. The results are stored and reported back to the calorimeter. This is amazing. Each vessel has its own statistics, from o-ring count, firing wire change, misfires, maximum temperatures and the test results.
Another great benefit will be the machine assembled vessel control card (the "brain"). Improved quality and reliability. The vessel electronics are now tested three times in the factory - after assembly, then after 24 hours oven burn-in, and then finally after packaging. All the times are recorded in the vessel memory together with such information as : Manufacturer, Dealer/ Agent , Customer, Assigned Serial Number.
