Medical research involves the cultivation of bacteria and other substances in culture flasks. These flasks must isolate the culture from outside influences during the cultivation process that might take some time.
The manufacturing process for the culture flash involves sonic welding of plastic components. It is important that the weld joints be leak tight to prevent the invasion of a culture experiment by foreign elements.
Cincinnati Test Systems incorporated the flexible Sentinel I24 pressure decay instruments to a manually loaded test stand. The fixtures position the flasks for sealing and confine their shape from excessive expansion during the low pressure leak test.
