I was reading a intertesting synth. that used a piece of equipment called "Carius tube" as a reaction vessel for 2 reagents that are allowed to react at 20-30 celsius. Does anyone know what this look like and what is it used for specificly? I googled some but with no result. Please help. Thank you.

Carius tube (bomb tube). A hard, glass thick-walled tube, sealed at one end, that is approximately 40 cm long.

Carius tubes are only useful to chemists that also are glassblowers, but fortunately there's a substitute available
Pressure Vessel, Griffin-Worden
Sealed-Tube Reactions: As a substitute for the Carius-type tube with the advantages that sealing with a torch is not required. Pressure release is conveniently and safely achieved prior to opening by means of a valve.

I believe that Carius tubes were used in the olden days before instrumental analysis as part of the procedure for determining the structure of a sugar wherein the sugar is reduced to a hydrocarbon by the action of aqueous HI at elevated temperature and pressure. I once found some (just very heavy wall pyrex tubing) in a stockroom where they had been laying untouched for perhaps decades.
All those moments will be lost in time, like tears in rain.

These four pages from Cohen's Practical Organic Chemistry; on using a sealed tube for an analytical procedure should bee quite helpful to any bee wishing to know how to work with such tubes for other procedures
