A fluid handling system with finger-tightened connectors for biological studies at kiloatmosphere pressures.

We present a high-pressure fluid handling system based around a simple-to-construct seal for applications in the biologically relevant kiloatmosphere range. Connectors are compact and finger tightened, as compared to the wrench tightening required of cone-type seals commonly used. The seal relies on an O-ring compression, and the system has been tested up to 2000 atm. While the system was designed for biological studies, it should be versatile enough for a wide range of applications, thus contributing finger-tightened convenience to the kiloatmosphere range.
