Liners

Removable, open top, cylindrical liners made either of borosilicate glass or PTFE can be furnished to fit most Parr reactors and general purpose vessels. These liners slide into the cylinder and require no additional fittings, but they may not coordinate with some alternate accessories and stirrers. Although they will not keep corrosive vapors from reaching the surfaces of the cylinder and head, they make it much easier to add and remove liquid reactants, and they give some protection to the cylinder when working with corrosive solutions. It must be noted, however, that adding a PTFE liner will slow the heat transfer rate into and out of the vessel, and it may be necessary to adjust the temperature control method to prevent overheating.
