Labware to handle hot aqueous NaOH This question regarding appropriate handling of hot concentrated aqueous $\ce{NaOH}$ - with particular concern for avoiding dissolution of borosilicate glassware and contamination of the $\ce{NaOH}$ solution and other reagents - led me to think of two possible solutions:


Coat the glassware with a silane, providing say a polyfluorinated or other inert protective coat
Avoid using glass, choose instead metal or plastic, if possible


Is either of these choices reasonable or common, or is there a better alternative? If so, which is best (considering chemical inertness, safety, complexity (including potentially cost), in that order of priority)?

In the case of choice 2, what commercial sources are there for such labware (for handling hot caustic solution for extended period). A cursory search - eg google and Merck website - did not turn up such products.

Note this question is about relatively small-scale labware (benchtop), not for reactors and the like. Volume max $\pu{5 L}$, $\pu{1 M}$ $\ce{NaOH}$, $\pu{&gt;100^oC}$, exposure time >1 h.
Instead of glassware, you might have to think about metallic containers. A 1 M NaOH solution should not be that harsh for stainless steel for a short period of time. Imagine, in the chlor-alkali industry, nothing is made of glass. The electrodes are made of titanium as far as I remember. If we were rich, a platinum lined crucible would have worked! Titanium might work too, very resistant to bases.

Regarding silanes, the Achilles heel is not the perfluoro functional group on the silane but the siloxane bond itself- i.e., the Si-O-Si ---- (functional group). Base will chew this bond apart into pieces even at pH 8-9. This is the biggest drawback of HPLC silica columns. We have not been able to synthesize any base stable silica bonding.
