Abstract
A residue tube assembly includes a residue tube having an open upper end and a cap assembly including a cap sealingly secured with the open upper end and an adjustable member assembled with the cap and defining an outlet passage extending into the residue tube to define a fill limit of the residue tube, and an overflow passage extending radially outward and downward of the open upper end of the residue tube. The adjustable member is vertically adjustable in the cap to adjust the fill limit of the residue tube.
Claims17
A residue tube assembly comprising:
- a residue tube including an open upper end;
- and
- a cap assembly including a cap sealingly secured with the open upper end and an outlet tube installed through an opening in the cap and adjustably secured through a coupling assembled with the cap, the outlet tube defining an outlet passage extending into the residue tube to define a fill limit of the residue tube, and an overflow passage extending radially outward and downward of the open upper end of the residue tube;
- wherein the outlet tube is vertically adjustable in the cap to adjust the fill limit of the residue tube.
A sampling container assembly comprising:
- a residue tube including an open upper end;
- a pipe surrounding the residue tube to define an inner cavity for receiving a heat transfer fluid;
- and
- a cap assembly sealingly secured with the open upper end of the residue tube, and defining an outlet passage extending into the residue tube to define a fill limit of the residue tube, and an overflow passage extending radially outward and downward of open upper end of the residue tube, the cap assembly comprising:
- a male threaded sleeve received around the residue tube in abutment with an outer lip at the open upper end of the residue tube;
- and
- a female threaded cap in threaded engagement with the sleeve to compress a gasket against the outer lip of the residue tube.
A sampling container assembly comprising:
- a residue tube including an open upper end;
- an inner pipe surrounding the residue tube to define an inner cavity for receiving a heat transfer fluid;
- an outer pipe surrounding the inner pipe to define an outer annulus;
- and
- a cap assembly sealingly secured with the open upper end of the residue tube and defining an outlet passage extending into the residue tube to define a fill limit of the residue tube, and an overflow passage extending radially outward and downward of the open upper end of the residue tube, into the outer annulus between the inner pipe and the outer pipe.
