Reactor Glass Liners

Many reactions need to run under pressure or at high temperature in a metal reactor or autoclave, but the metal can contaminate sensitive products or be corroded by aggressive chemistry. A glass liner solves both problems: it drops inside the metal vessel and gives the reaction an inert borosilicate surface, while the metal vessel still provides the pressure containment.

So the liner pairs the chemical inertness of glass with the mechanical strength of a steel reactor — the product only ever touches glass, and the expensive reactor is protected from corrosion.

A cylindrical borosilicate 3.3 liner sized to fit the cavity of a specific metal reactor or autoclave. It provides the inert wetted surface; the metal vessel provides pressure containment. Dimensions are matched to the reactor so the liner seats correctly and the lid or seal closes over it.

The liner is not itself a pressure vessel — it relies on the metal reactor for containment, so pressure and temperature limits are set by the reactor system, not the glass. Fit the liner to the matching reactor, avoid thermal shock by heating and cooling gradually, and inspect for cracks between runs, since a flawed liner can fail and expose the metal to the reaction.

Formed from borosilicate 3.3 into a cylinder sized to the target reactor cavity, then annealed. Dimensional accuracy (so it fits the reactor and seals correctly) and wall integrity are the key checks; liners are made to suit specific reactor models.
