Abstract
A sampling container assembly includes a sample receiving residue tube, a residue tube cap, inner and outer pipes, a container cap, a fixture block, and a supply conduit. The residue tube cap is assembled with the residue tube and defines inlet and outlet ports. The inner pipe has a lower end sealingly mounted to the fixture block and surrounding the residue tube to define an inner cavity for receiving a heat transfer fluid. The outer pipe has a lower end sealingly mounted to the fixture block and surrounding the inner pipe to define an outer annulus, with the container cap sealingly assembled with an upper end of the outer pipe. The supply conduit extends through the fixture block and the outer annulus and is connected with the inlet port of the residue tube cap for providing a sample fluid to the residue tube. The fixture block defines a passage extending to the outer annulus for supplying a chilling fluid to the outer annulus for chilling the heat transfer fluid in the inner cavity.
